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 on the inside flaps. Flower Structure Flower Functions Open your foldable and label it like this on the inside flaps. Leaf Structure Leaf Functions Stem Structure Stem Functions Root Structure Root Functions

Label your foldable like this on the back cover. Make sure you draw lines to separate. Flower Adaptations Leaf Adaptations Stem Adaptations Root Adaptations

Fill in your foldable with the notes provided. The notes are separated by ORGAN name. Only write under that ORGAN’s flaps for slides AFTER the Organ Name.

Top Flap Organ: Flower

Anther plant sperm Pollen Stigma Style Ovary produces pollen Structure Anther Pollen Stigma Style Ovary Function produces pollen plant sperm Sticky top of style where pollen lands. Tube that 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.

Second Flap Organ: Leaves

Cuticle Stomata Chloroplast Structure Function Wax to prevent water loss Gas exchange and Transpiration (water loss High to Low- osmosis) Photosynthesis

Adaptation to Environment Thick cuticle in dry climates. WHY? Fewer stomata. WHY? Reduced surface area(ex. Cactus) WHY?

Third Flap Organ: Stems

-vascular tissue (tubes) carries water UP the plant - roots to leaves Structure Xylem Phloem Function -vascular tissue (tubes) carries water UP the plant - roots to leaves Vascular tissue (tubes) Carries sugar down the plant to be stored in roots. Can go up and down stem

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

Last Flap Organ: Roots The Anchors

Fibrous Roots Root hairs Taproots Roots that are web like Structure Fibrous Roots Root hairs Taproots Function Roots that are web like Extensions of fibrous roots to increase surface area for water One large root with root hairs to store carbs

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.

What organ is primarily used for photosynthesis and why?

What is the difference between xylem and phloem?

What is an adaptation roots can have to store sugar?

Why would a plant need color or nector?

What is transpiration?

Why do plants have cell walls?

Why would plants have thicker cuticles? Where would these plants live?
