Plant Systems (Structures, Functions) & Adaptations

Fold your sheet in half.

Cut flaps by cutting the FIRST layer only. RootSystem ShootSystemReproductiveSystem Label the systems and draw the arrows. Label the parts on the front. Flower Leaf Stem Roots

Fill in your foldable with the notes provided. Structure will go on the left side and Function will go on the right. Adaptations to the environment will go on the back.

Flowers reproductive organ of a plant

StructureAntherPollenStigmaStyle Ovary (Fruit) Function - produces pollen - haploid male gametes (sex cells) - Sticky top of style where pollen lands. - Transports pollen to the ovary. - Female organ which produces female gametes. A ripened ovary is the fruit, the seed is the embryo.

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

Leaves- photosynthetic organ of a plant

StructureCuticleMesophyllVeinsStomataFunction - Prevents water loss - Photosynthesis - Xylem & Phloem - Lets CO 2 in and O 2 and H 2 O out

Adaptation to Environment 1. Thick cuticle in dry climates. 2. Few stomata to prevent water loss. 3. Thick stem to store water (cactus)

Stems

StructureXylemPhloemFunction - 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 glucose (food) from the leaves to other parts of the plant.

Adaptation to the Environment 1.Stiff cell walls for trunks and branches. 2.Dead Xylem becomes the wood on the inside of tree trunks. 3. Can be modified to store food. Ex: Tubers (potatoes) and Bulbs (garlic, onions)

Roots

Structure Epidermis & root cap Root hairs Root tips (apical meristem) Function -protection and absorption of water and minerals. -increase surface area for absorption of water & nutrients - tip of root that is growing into the soil (area of mitosis).

Adaptations to the Environment 1.Can be modified to store starch and sugar. (Carrots, Beets, Turnips) 2. In dry climates taproots form & can be extremely long to reach & store water. 3.Fibrous roots are good for preventing erosion and getting surface water due to being a thin and branching root system. 3. Fibrous roots are good for preventing erosion and getting surface water due to being a thin and branching root system. 4.Capillary Action - force that allows the roots and the stem to absorb the water up in to themselves, against the force of gravity
