Structure and Function of Plants Foldable

Fold your sheet in half along the crease line.

Open your foldable and label it like this. Structures Functions Open your foldable and label it like this. Draw lines that match those on the front.

Cut flaps on folds by cutting the first layer only.   

Flowers Flowers

Anther -produces pollen Pollen Stigma & Style Ovary Structure Anther Pollen 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 Floral

Fertilization of a flower Stamen (male) Pistil (female) Fertilization of a flower

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

Leaves

Structure Upper Epidermis Palisade Layer Spongy Layer Lower Epidermis Function -contains cuticle; prevents water loss Light reactions of photosynthesis. Photosynthesis and storeage of CO2, O2, and H2O Lets CO2 in and O2 out and water out through stoma; controlled by guard cells

Adaptation to Environment Thick cuticle in dry climates. Few stomata to prevent water loss. Reduced surface area of leaves to prevent water loss. (Cactus spines) Leaf Adaptations

Stems 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. Vascular tissue

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

Roots

-protection and absorption of water and minerals. Structure Epidermis and root cap Root hairs Root tips 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 Environment Can be modified to store starch and sugar. (Carrots, Beets, Turnips) In dry climates root systems can be extremely long to reach water or spread out on the surface. Anchor plant into soil. Types of roots
