Term
Stoma/stomata
Definition
where gases diffuse
Term
xylem
Definition
carries water from roots to the leaves
Term
Phloem
Definition
Carries food/glucose from the leaves to the roots
Term
Why do leaves change color?
Definition

Chlorophyll breaks down

Due to lack of light

To save energy

Term
List the limiting factors
Definition

Light

Temperature

Carbon dioxide

water

Term
light as a limiting factor
Definition
If there is NOT enough light, then the light-dependent reaction will not happen
Term
Temperature as a limiting factor
Definition
The warmer the temperature the faster the molecules move, meaning the reaction can happen faster
Term
Carbon dioxide as a limiting factor
Definition
If there is NOT enough carbon dioxide, then the plant won't have enough carbon to make glucose
Term
Water as a limiting factor
Definition
If there is NOT enough water, then the plant won't have enough hydrogen to make glucose
