Photosynthesis

Question 1

basic equation for photosynthesis

Answer 1

6CO2 + 12H2O → C6H12O6 + 6H2O + 6O2

Question 2

process whereby green plants convert the radiant energy of light into chemical energy that is then stored in food molecules

Answer 2

Photosynthesis

Question 3

photosynthesis to occur must be present

Answer 3

light, a green pigment and carbon dioxide

Question 4

who are dependent on the products of photosynthesis for their energy, for the raw materials necessary for growth and repair

Answer 4

All living things

Question 5

Photosynthesis

Answer 5

takes place in chloroplasts

Question 6

the main product of photosynthesis

Answer 6

Glucose

Question 7

photosynthesis, follows three different pathways

Answer 7

1) it is converted into other chemical substances required by plant cells (e.g., cellulose in cell walls);

2) it is converted into starch, a storage molecule that can be broken down to glucose again when the plant requires it; and

3) it is broken down during cellular respiration to release energy needed by plants for growth and development.

Carbon Dioxide as a Requirement for Photosynthesis

Answer 9

dilute phenol red solution experiment
