Flashcards in Chapter 4 Deck (15)
1

stomata

the tiny holes on the undersurface of the leaf to take in oxygen and release carbon dioxide.

2

transpiration

the process by which plants leak water vapor into the air through the open stomata

3

Guard cells

double doors that open and close the stoma --- also protects it.

4

xylem

the type of tissue in vascular plants that provides support and conducts water and nutrients from the leaves to the middle structure of the plant

5

phloem

the tissue that conducts food in vascular plants - flows down

6

respiration

the process of taking in oxygen and releasing carbon dioxide

7

photosynthesis

the process by which plants, algae, and some bacteria use sunlight, carbon dioxide, and water to make food.

8

root hairs

some cells of the epidermis extending from the root that takes in water.

9

chloroplast

contain chlorophyll that captures energy from the sun - used to make food and is located on the upper side of the leaf.

10

chlorophyll

a green pigment that captures light energy for photosynthesis.

11

fossil fuel

a nonrenewable energy resource formed from the remains of organisms that lived long ago ---- can be burned to release energy

12

the process of photosynthesis

carbon dioxide + water - in the presence of chlorophyll and sunlight = glucose + oxygen

13

combustion

the process of burning fossil fuels.

14

decomposition

the process of decaying

15

Cuticle

a waxy outer structure that protects plants from drying out.
