Question

Scientists conducted an experiment to determine how different wavelengths of light affected photosynthesis. They used two groups of the same plants. The leaves of group 1 were covered with transparent green plastic. The results show that the pants photosynthesized best when their leaves were not covered in any plastic. Which hypothesis do the results support?

a. If leaves are uncovered, then their chloroplasts will produce more oxygen than the leaves that are covered in green plastic.
b. If leaves are covered in green plastic, then their mitochondria will absorb more carbon dioxide than the mitochondria of uncovered leaves.
c. If leaves are uncovered, then their chloroplasts will release more carbon dioxide than the chloroplasts of leaves covered in green plastic.
d. If leaves are covered in green plastic, then their mitochondria will produce more oxygen than the leaves that are uncovered.

Answer 1

The correct answer is a if leaves are uncovered,then their chloroplast will produce more oxygen than the leaves that are covered in green plastic.

Step-by-step explanation:

The photosynthesis process is affected by different wave length of light because different pigments absorb different wave length of light.

If the leaves of one plant are covered with transparent green plastic,then there will be no problem for the plant to absorb different wave length of light as the plastic is transperant.

But after photosynthesis less oxygen will be released from the leaves covered by green plastic because here the green plastic will act as a barrier in the diffusion of oxygen from the plastic covered leaves to the atmosphere.
