Fungi Kingdom Fungi are multicellular non vascular and

have cell walls made of chitin not cellulose as in plant cells

Many fungi play a key role in decomposition recycling nutrients since they secrete enzymesto digest their food source externally absorbing the required nutrients

Some fungi are unicellular such as yeast cells

Multicellular fungi are composed of tinyfilaments that are tube like structures called hyphae

Masses of these hyphae form mycelium which is the body of the fungus Thousands of these tiny tubes extend into soil to absorb water and nutrients

This mass of filaments creates huge surface area to volume ratio particularly advantageous for plants Why

The fungal filaments and the roots of plants form mycorrhizae This increases the absorption of minerals and water gt90 of all terrestrial plants have a mutualistic relation with fungi for this reason

Key Features Fungi donrsquot move They grow filaments in any

directions rapidly instead

The part we see easily of fungi are their fruiting bodies (Eg Mushroom)

Fungi obtain nutrients from other organisms by decomposing feeding on living things or having mutually beneficial relations

Filaments are only one cell thick which presents a lot of surface area to allow absorption biological material in every terrestrial environment

Fungi propagate by spores that attach to animals or wind drift Spores made in great numbers (trillions)

Sexual and asexual reproduction Both involve fruiting body ejecting spores above mycelium

SexualAsexual reproduction

Classification of Fungi 5 different Phyla

Evolutionary origin of plants

Evolutionary Origin of Plants

Evolutionary Origin of PlantsThe ancestors of todays plants were photosynthetic protists probably very similar to todayrsquos algae This concept is supported by several key points of evidence

1 Use of the same chlorophyll molecules

2 Both have cellulose in their cell walls

3 Store energy in the form of starch molecules

4 DNA analysis shows close relationship

Evolutionary Origin of PlantsIt stands to reason that todays plants evolved from protists living in fresh water habitats since here the evolving plants would have to develop ways structures that would allow them to withstand changing temperatures (daily and seasonally) as well as periods of drying out (desiccation)

Ultimately the emerging protists would accumulate adaptations that would allow them to be completely terrestrial

Evolutionary Origin of PlantsThese early land inhabitants no doubt needed to be close to their watery origins Here before the development of vascular systems they could simply absorb water amp nutrients directly from the ground

The evolution of vascular tissue (tubes to carry water and food) throughout the plant body allowed for plants to grow upward towards dryer habitats

Fig 21-1 p406 Draw on paper use polarbear txt

Key Features of Plants Plants are multicellular photosynthetic organisms

Most distinctive feature is reproduction

They have alternating multicellular haploiddiploid generations

Key Features of Plants Alteration of Generations draw on board

In diploid generation portion of their lifecycle the plant consists of diploid (2n) cells and is called a sporophyte

This can produce spores (through meiosis) and these haploid cells land on the ground and grow into multicellular haploid plants called gametophytes

These produce malefemale gametes (mitosis) which join and eventually grow into 2n sporophyte plantshellip completing this cycle

Terrestrial LifeLife on land was very challenging for the first

land plants They faced

drying winds An inconsistent supply of water No mechanisms through to gather nutrients No watery medium through which the sperm

could reach the egg Difficulty supporting a plant body without the

natural buoyancy of water to hold them up

Adaptations Common

Roots (anchor absorb waternutrients)

Waxy cuticle (limit evaporation)

Pores (stomata allow gas exchange)

Conducting vessels (transport waterminerals)

Lignin (rigid polymer)

A waxy cuticle developed to help reduce the drying effect of the winds

Stoma

Stoma - singular

This required stoma to allow for movement of gases into and out of the leaf

Preventing Water Loss The cuticle does not let oxygen or carbon dioxide pass

through it Pores called stomata permit plants to exchange oxygen

and carbon dioxide Stomata extend through the cuticle and the outer layer of

cells A pair of guard cells border

each stoma Stomata open and close

as the guard cells change shape

Stoma open and close in response to current conditions

- Dry hot weather causes them to close to conserve water

- They open during normal conditions to allow CO2 to enter the plant and O2 to leave Water also escapes at this time

Roots developed so water could be drawn into the plant from the soil

(Increase Surface Area)

Vessels were needed to transport water within the plant

Development of Pollen

Pollen carry the gametes in the absence of waterFirst used wind to disperse then animals because more effective

Structural support was needed to grow upright against gravity

Lignin reinforced cell walls provided the necessary strength

Stoma open and close in response to current conditions

- Dry hot weather causes them to close to conserve water

- They open during normal conditions to allow CO2 to enter the plant and O2 to leave Water also escapes at this time

Roots developed so water could be drawn into the plant from the soil

(Increase Surface Area)

Vessels were needed to transport water within the plant

Development of Pollen

Pollen carry the gametes in the absence of waterFirst used wind to disperse then animals because more effective

Structural support was needed to grow upright against gravity

Lignin reinforced cell walls provided the necessary strength

Terrestrial LifeLife on land was very challenging for the first

land plants They faced

drying winds An inconsistent supply of water No mechanisms through to gather nutrients No watery medium through which the sperm

could reach the egg Difficulty supporting a plant body without the

natural buoyancy of water to hold them up

Adaptations Common

Roots (anchor absorb waternutrients)

Waxy cuticle (limit evaporation)

Pores (stomata allow gas exchange)

Conducting vessels (transport waterminerals)

Lignin (rigid polymer)

A waxy cuticle developed to help reduce the drying effect of the winds

Cuticle waxy layer covers upper surface

Protects leaf against water loss

Vessels transports water nutrients and food

Stoma

Stoma - singular

Stomata - plural

This required stoma to allow for movement of gases into and out of the leaf

Preventing Water Loss The cuticle does not let oxygen or carbon dioxide pass

through it Pores called stomata permit plants to exchange oxygen

and carbon dioxide Stomata extend through the cuticle and the outer layer of

cells A pair of guard cells border

Tuesday Major Groups of Plants

Major Groups Two major groups

Bryophytes (nonvascular meaning cannot retain or deliver water)

Tracheophytes (vascular plants meaning water conducting)

Bryophytes Lack roots leaves and stems Are anchored by

rhizoids Rely on diffusion or poor conductive tissue to

distribute nutrients This is why they are small No stiffening agent Eg Liverwort moss

Bryophyte reproduction

Vascular Plants Distinguished from bryophytes by conducting cells

called vessels Stiffening agent called lignin

These both allow taller growth

Diploid sporophyte generation more evident than haploid gametophyte

Vascular 2 groups

Seedless vascular plants (Pteridophyte)

Seed vascular plants (Spermatophyte)

Seedless Vascular Plants Club mosses horsetails ferns

Seedless vascular plants require water for sperm They do not have seeds just spores

They used to be the dominant plants type on earth and be much larger

Today we use there ancient remains for

Club mosses and Horsetails Club mosses grow a few inches tall Resemble

mosses Commonly known as ground pine

Horsetails are less than a meter tall Only 15 species left Sometimes called ldquoscouring rushrdquo due to silica in outer layer of cells

Ferns Most diverse of seedless vascular plants (12000)

In the tropics some are still very tall like their ancestors (carboniferous)

Wednesday Seed plants

Seed Plants dominate the land Why do you think this

Pollen and seeds

Pollen are structures that carry sperm-producing cells Dispersed by windanimals Not limited to water meaning they are fully adapted to life on dry land

Seed Plants dominate the land Seeds are a protective outer layer and

embryonic plant and food supply This allows for suspended animation (dormant)

Pine Seed

Bean Seed

Seed Plants Types Nonflowering (Gymnosperms)

Flowering (Angiosperms)

Nonflowering Seed Plants (Gymnosperms) Conifers Ginkgos Cycads

Conifers Evolved before flowering plants Eg Conifers Adapted to cold and dry climates 3 ways

Conifers retain green leaves to grow all year Leaves are covered in thick substance to stop

evaporation The sap has antifreeze

Life Cycle of Pine

Ginkgorsquos and Cycads Less abundant now a days Ginkgo was probably

the first seed plant to evolve (Jurassic 208 mill) Gingko tree is either male of female The female

bears a foul smelling seed Would have been extinct but are still cultivated in

Asia Cycads are large ferns 3-65 feet tall and can live

5000years

Flowering Seed Plants (Angiosperms)

Flowering Seed Plants (Angiosperms) Dominate the earth for the last 100 million years Three major adaptations contributed to the

enormous success of angiosperms

Flowers

Fruits

Broad leaves

Angiosperms Flowers are both male and female gametophyte

Flowers probably formed when angiosperms made an association with animals (insects) by carrying pollen from plant to plant

Natural selection favored showy flowers

Angiosperms The ovary surrounding the seed of an angiosperm

matures into a fruit

Fruits entice animals to disperse seed

Some pass through digestive track unharmed others cling to fur of animals such as burrs others like maple seed fruits make propellers and use wind

Angiosperms Broad leaves capture more sunlight

When water is in short supply the leaves fall off to reduce evaporation

Have evolved defenses against animals such as thorns spines resin poison distaste

We use the chemical compounds of these defenses for medicine and food

Dicot MonocotMonocot

In monocots there is only one leaf

Corn grass tulips daffodils irises lilies and palm trees are monocots

Monocots have parallel veins in their leaves

The leaves generally lack stalks at the base

The flowers tend to have petals in multiples of three

Dicots

Buttercups peas roses sunflowers maple trees and dandelions are dicots

The leaves have branching veins

The flowers have petals in multiples of four or five

the first seed plant to evolve (Jurassic 208 mill) Gingko tree is either male of female The female

bears a foul smelling seed Would have been extinct but are still cultivated in

Asia Cycads are large ferns 3-65 feet tall and can live

5000years

Flowering Seed Plants (Angiosperms)

Flowering Seed Plants (Angiosperms) Dominate the earth for the last 100 million years Three major adaptations contributed to the

enormous success of angiosperms

Flowers

Fruits

Broad leaves

Angiosperms Flowers are both male and female gametophyte

Flowers probably formed when angiosperms made an association with animals (insects) by carrying pollen from plant to plant

Natural selection favored showy flowers

Angiosperms The ovary surrounding the seed of an angiosperm

matures into a fruit

Fruits entice animals to disperse seed

Some pass through digestive track unharmed others cling to fur of animals such as burrs others like maple seed fruits make propellers and use wind

Angiosperms Broad leaves capture more sunlight

When water is in short supply the leaves fall off to reduce evaporation

Have evolved defenses against animals such as thorns spines resin poison distaste

We use the chemical compounds of these defenses for medicine and food

Dicot MonocotMonocot

In monocots there is only one leaf

Corn grass tulips daffodils irises lilies and palm trees are monocots

Monocots have parallel veins in their leaves

The leaves generally lack stalks at the base

The flowers tend to have petals in multiples of three

Dicots

Buttercups peas roses sunflowers maple trees and dandelions are dicots

The leaves have branching veins

The flowers have petals in multiples of four or five
