Question

A greenhouse is filled with air that contains more carbon dioxide than normal air has. how might photosynthesis and plant growth be affected?

Answer 1

The greenhouse filled with air containing more carbon dioxide than the normal air will promote the growth of the plant by increasing the rate of the photosynthesis. The water loss by the process of transpiration is reduced considerably, and the water-use efficiency is increased. This will result in a elevated growth of the greenhouse plants.

Hence, the answer is 'the photosynthesis rate will be increased which will increase the plant growth'.
