Eukaryotic (nucleus) Cell Wall (cellulose) Multicellular Autotrophic § Photosynthesis § Chloroplasts

Plants Nonvascular Vascular Angiosperms Monocots Dicots Gymnosperms

NONVASCULAR PLANTS Early Plants have no vessels, no roots, no stems or leaves. Examples: Mosses & Liverworts

VASCULAR PLANTS Modern Plants have vessels to transport food and water. They have roots, stems and leaves. Most reproduce by seeds. Example: Grass, corn, trees, flowers, bushes

GYMNOSPERMS § "naked seeds" § cone bearing (seeds grow on cones) § needle like leaves § usually stay green year round § wind pollinated § Examples: pine trees & evergreens

ANGIOSPERMS § flowering plants § Seeds enclosed in a fruit § most pollinated by birds & bees § have finite growing seasons § Examples: grasses, tulips, oaks, dandelions § Divided into two main groups: Monocots & Dicots

Ex. Lilies, onions, & corn Ex. Trees & ornamental flowers

Parts of the Plant

Foldable Instructions § Fold a WHITE piece of paper in half § On the cover draw a flower (include flower, stem, leaves, and roots)

After drawing the flower, cut the drawing in 3 sections (flaps) § one for the flower § one for the stem and leaves § and one for the roots

§ Then under each flap you will be writing the corresponding information for each part.

Flower § Reproductive organ of the plant § § § Flowers are usually both male and female PETAL: Leaf like flower organs, usually brightly colored. STAMEN: Male reproductive organ of a flower consisting of an anther and a filament. § ANTHER: Pollen producing structure located at the tip of a flower’s stamen. § PISTIL: Female reproductive organ of a flower

DRAW IN INB, LEFT SIDE.

Stems – complete on foldable § Organ that provides support and growth; transport water through xylem and nutrients through phloem; organ from which leaves grow, can serve as storage. § Two types of stems: herbacious and woody § Xylem: vascular plant tissue made up of tubular cells that transport water and dissolve minerals from roots to the rest of the plant § Phloem: Vascular plant tissue made up of tubular cells joined end to end; transport sugars to all parts of the plant.

Leaves – complete on foldable § Photosynthetic organ of the plant, used to convert sunlight into food § Photosynthesis Equation: Parts Stomata: pores that let CO 2 in and O 2 out. Cuticle: waxy layer on upper surface that protects against water loss. Veins: Veins transports water, nutrients and food. Made of xylem and phloem. Cuticle Veins Stomata

Functions of Roots 1. 2. 3. 4. Anchor & support in the ground Absorb water & minerals Hold soil in place Two types: taproots fibrous roots Taproot Fibrous Roots
