3. STOMATA exchange O2 and CO2 for photosynthesis
STOMATA exchange O2 and CO2 for photosynthesis. They’re REGULATED by GUARD CELLS that open and close the stomata.

4. DERMAL TISSUE
OUTER layer
Like skin
Waxy coating on leaves and stems

5. GROUND TISSUE Makes up the INSIDES Supports the plant Stores glucose
Contains chloroplasts!
Photosynthesis happens here

6. MERISTEMATIC TISSUE Located only at the root tips
Uses mitosis to extend the roots of the plant

7. VASCULAR TISSUE Like the veins + arteries
Transports water, sugar and nutrients
2 TYPES:
XYLEM = moves WATER from roots  leaves
PHLOEM = moves SUGAR from leaves  stems and roots

9. TRANSPIRATION = H20 vapor evaporates through the stomata via the XYLEM
TRANSPIRATION = H20 vapor evaporates through the stomata via the XYLEM. ROOTS  STEM  LEAVES
REQUIRES THE USE OF: 1. ADHESION (water to water)
2. COHESION (water to the xylem)
