Functions of plants Quiz 13A. Plants are supported by two related systems: cell walls- cellulose turgor pressure - water pressure inside a plant cells.

1.The leaf contains a waxy layer at the top, palisade layer, and spongy mesophyll layer. 2.Guard cells can change the size of stomata 3.The xylem carries.

Roots Roots anchor the plant. Roots absorb water and dissolved minerals from the ground. Roots may also be modified to store food. Ex. Carrots, radish,

Seed Plants Leaves- where the food making process (photosynthesis) occurs.

Plant Structure & Function

Plant Structure Root System Shoot System –Stem –Leaves –Flowers

Root System Function Anchors Absorption Transportation Storage Structure Xylem Water & minerals from roots to leaves Phloem Sugars from leaves to roots

Root Types Taproots Fibrous Roots Adventitious

Shoot System - Stems Function Supports leaves Grows toward light Transports substances between roots and leaves Structure Herbaceous Soft and green Do not survive winter Woody Increases in size due to vascular cambium Survives winter

Shoot System - Stems Herbaceous StemWoody Stem

Woody Stems Key terms to know: Vascular Cambium Sapwood Heartwood Cork/Bark Resin/oil

Shoot System - Leaves Function Photosynthesis –Uses carbon dioxide –Produces oxygen and glucose Structure Designed to capture maximum light and minimize water loss

Shoot System - Leaves Key terms to know: Cuticle Epidermis Palisade layer Spongy mesophyll Veins (xylem & phloem) Stoma & guard cells Chlorophyll (plastids) Turgor pressure

Angiosperms Known as the flowering plants Divided into two types Monocotyledons (monocots) Dicotyledons (dicots)

Monocots vs. Dicots
