Question

Why is the rate of photosynthesis higher?

1) Because leaves have chloroplasts
2) Because leaves have mitochondria
3) Because leaves have a higher concentration of carbon dioxide
4) Because leaves have a higher concentration of sunlight

Answer 1

The rate of photosynthesis is higher in leaves due to the presence of chloroplasts containing chlorophyll.

Step-by-step explanation:

The rate of photosynthesis is higher in leaves due to the presence of chloroplasts which contain the pigment chlorophyll. Chlorophyll absorbs light energy, which is essential for photosynthesis.

The rate of photosynthesis is not directly influenced by the presence of mitochondria, concentration of carbon dioxide, or concentration of sunlight in leaves.
