Gas Exchange Requirement

Plants need to exchange gases (CO2CO2 and O2O2) for photosynthesis and respiration.

2
New cards

Primary Gas Exchange Structure

Gas exchange primarily occurs through structures called stomata.

3
New cards

Stomatal Density

Number of stomata per unit area on a leaf.

4
New cards

Importance of Stomatal Density

Affects the rate of gas exchange and transpiration.

5
New cards

Factors Influencing Stomatal Density

Light availability, CO2CO_2 concentration, water availability.

6
New cards

Xylem Function

Vascular tissue transporting water from roots to leaves.

7
New cards

Transpiration

Loss of water vapor through stomata.

8
New cards

Cohesion-Tension Theory

Water is pulled upward due to transpiration; cohesion and adhesion help move water.

9
New cards

Adaptations to Arid Environments

Thick cuticle, sunken stomata, CAM photosynthesis.

10
New cards

Adaptations to Salty Environments

Salt excretion glands, selective ion uptake.
