Fungi

Neither plants or animals.

Has cell walls (like plants) but no

chlorophyll

Heterotrophic (like animals)

A fungus obtains nutrients from its food

source by secreting enzymes onto it,

breaking it down so that it can be

absorbed. Plays an important role in the

decomposition of organic matter in the

environment.


2/11

Fungi use spores to reproduce

4 main groups based on shape ofspore producing structures:

1. Threadlike Fungi (~600 knownspecies ofmold)

2. Sac Fungi (~30,000 species

including yeast and mildew)

3. Club Fungi (25,000 species.Includes mushrooms)

4. Imperfect Fungi (25,000 species.Includes Penicullium from whichcame the discovery ofpenicillin andantibiotics)

Monerans

Unicellular (No nucleus)

- Smallest and simplestlifeforms

Bacteria and Archaea Bacteria (millions of

different species, 20,000alone in 1 litre of seawater)500-1000 species in the

human digestive system,very important for thebreakdown of food andnutrients.


4/11

Archaea evolved separately frombacteria (different cell wall structure,etc)

They exist in extreme environments:

Thermophiles in geysers

Halophiles in hypersaline salt lakes

Methanogens produce methane andcannot survive in oxygenatedenvironments

Protists

Single or multi-cellular

More complex than monerans

3 categories Animal-like,fungus-like & plant-like

Animal-like protists

(protozoans) are able to moveand obtain their food

(heterotrophic, unicellular)


6/11

Fungus-like protists have all

the trademarks of fungi (cell

walls, spores, etc) but they canmove

Plant-like protists arecommonly called algae, which

are autotrophic and use

photosynthesis for energy.

Plants

4 main groups


8/11

1. Confiers and Cycads

Produce seeds on scales of a woody cone.

Contain cells that transport food and wateraround the plant


9/11

2. Angiosperms

higher plants, well developed systems and

diversity in structure and function.

Ability to live in variety of climatic conditions Flower is the part where fertilization occurs

and seeds are formed

Contain cells that transport food and wateraround the plant


10/11

3. Ferns

Do not produce seeds

They reproduce through spores which develop

on cases under their leaves Contain cells that transport food and water

around the plant


11/11

4.Mosses and Liverworts

Do not have well developed transport system

or true roots

Generally found in cooler moist environments
