Module 19 Lesson 2

Functions are: Storage Photosynthesis gas exchange protection tissue repair and replacement

Functions are: Support Transport materials

Functions are: Support for surrounding tissues providing flexibility for plant tissue repair and replacement

where the plant is growing, spreads throughout the plant

layer of cells that makes up outer covering of a plant, protects plant

transporting water, food, and dissolved substances throughout plant

boundary from outside to help protect cell, controls what goes in and out

Opens and closes to allow gases in and out of plant

Cells that open or close the opening of the stomota

Protects plant from predators by guarding leafs with toxins, reflects light, etc.

Transports water from roots to leafs Made from vessel element and Tracheids that are both tubular and cylinder plant cells allowing different materials to move through them

Transports glucose from photosynthesis Made from sieve tube members and companion cells

Anchors the plant and absorbs nutrients and water from the soil

protects the roots tissues and the meristem Located at tips of roots

Green and flexible

Harder and more durable

transports materials, support the leafs and reproductive structures

process in which water evaporates from the inside of leaves to the outside through stomata.

Photosynthesis

Provide space for gas exchange needed for photosynthesis

Captures light and converts energy into glucose LOTS OF CHLOROPLASTS

Plants growth response to external stimulus

growth toward light source

positive downward growth or negative upward growth
