What is photosynthesis?
Synthesizing molecules of water
Synthesis of ATP
The process by which a living plant makes food in presence of chlorophyll, light, water, and CO2, releasing O2
Which of these is NOT a factor affecting photosynthesis
Light intensity
Water content
CO2 concentration
Siza of vacuoles
What is translocation?
The movement of food to various parts of the plant via phloem
The loss of water in a plant through cuts
The upward movement of water through the xylem
None of the above
Which of these is NOT an adaptation made in leaves to facilitate photosynthesis?
Large surface area
Needle-like leaves
Numerous stomata
Higher concentration of chloroplasts
Pick the correct order of options:
1- CO2 diffuses into the leaf through stomata and water is taken in through the roots
2- 6CO2 + 6H2O → C6H12O6 + 6O2
3- Chlorophyll is activated and photolysis occurs
4- H+ ions are picked up by NADP

What are the products of photosynthesis?
lipids
carbs and reactants essential for aerobic respiration

What is the role of Chlorophyll in photosynthesis?
It breaks the hydrogen bonds in water molecules
It converts light energy into chemical energy contained in bonds
It releases absorbs green light waves and reflects all of the other ones
it provides energy for the light dependent reactions
