• Water
• Light
• Oxygen

• Carbon dioxide
• NADPH and ATP from LR
• Sugars

abiotic environment --> plants --> herbivores, omnivores, carnivores --> detrivores

A pore complex that opens when turgid and lets gas enter (importantly O2 and CO2 for respiration and photosynthesis) and closes when flaccid.

1. Hexose Phosphates -->

• 2a. Sucrose (glucose-fructose) ~ transport
• 2b. Cellulose
• 2c. Starch ~ storage
• 2d. Pentose Phosphate -->

3. DNA, RNA, Lipids, etc

• 1. Carboxylation:
•    
•     R1,5BP + CO2 + H2O --> (2) 3PG

2. Reduction

•     3PG + ATP + NADPH --> G3P
•     G3P --> triose phosphate --> etc

3. Regeneration

    G3P + ATP --> R1,5BP

Chlorella

Lollipop (continuous strains of algae grown and light shined on it. 14C injected and algae content analyzed)

Two dimensional paper chromatography where after 2 hours, the paper rotated 90 degrees (gives difference in height AND length).
