Question

match the letter with the inputs/outputs of photosynthesis.
column a
1 a
2 b
3 c
4 d
column b
a. water
b. glucose
c. oxygen
d. carbon dioxide

Explanation:

In photosynthesis, light energy (1) is absorbed by chlorophyll in the chloroplast (2). Water (entering as 2) is split, releasing oxygen (3) as a by - product. Carbon dioxide (6, 7) is used to make glucose (5).
1 is light energy, not directly matched to Column B options. But considering the process, water enters the chloroplast for the light - dependent reactions where it is split. So 2 is water. Oxygen is released as a result of water - splitting in the light - dependent reactions, so 3 is oxygen. Glucose is the end - product of the Calvin cycle (the dark reactions), so 4 is glucose.

Answer:

1. No match
2. A. Water
3. C. Oxygen
4. B. Glucose
