Structure and Function of

Plants Review and Foldable

Fold your sheet in half along the crease line.

Cut flaps on folds by cutting the first layer only.

Open your foldable and label it like this.

Structures Functions

Fill in your foldable with the notes provided. Structure will go on one side and function will go on the other. Adaptations to the environment will go on the back.

Flowers

Structure

AntherPollen

Stigma & Style

Ovary

Function

-produces pollen-haploid male gametes (sex cells)-Sticky top of style where pollen lands. The Style transports it to the ovary. ----------Female organ which produces female gametes

Adaptation to Environment

1. Bright colors and sweet nectar to attract pollinators.2. Development of Fruit for seed dispersal.

Leaves

Structure

Upper EpidermisPalisade LayerSpongy LayerLower Epidermis

Function

-contains cuticle prevents water loss-Light reactions of photosynthesis.

-Calvin cycle (stores CO2)

-Lets CO2 in and O2 and water out (stomata)

Adaptation to Environment1.Thick cuticle in dry climates.2.Few stomata to prevent water

loss.3.Reduced surface area to

prevent water loss. (Cactus)

Stems

Structure

Xylem

Phloem

Function

-vascular tissue (tubes) that carry water from the roots to the leaves for photosynthesis and to other parts of the plant.-Vascular tissue (tubes) that carry sugar from the leaves to other parts of the plant.

Adaptation to the Environment

1.Stiff cell walls for trunks and branches. Dead Xylem becomes the wood on the inside of tree trunks.

2. Can be modified to store food. Ex. Tubers (potatoes) and Bulbs

Roots

Structure

Epidermis and root cap

Root hairsRoot tips (apical meristem)

Function

-protection and absorption of water and minerals.-increase surface area for absorption- tip of root that is growing into the soil (area of mitosis).

Adaptation to the Environment1.Can be modified to store

starch and sugar. (Carrots, Beets, Turnips)

2. In dry climates root systems can be extremely long to reach water.
