Expert Answer
1. (i)Chloroplasts contain chlorophyll that absorb light energy for photosynthesis so more chloroplasts means a higher rate of photosynthesis.
(ii)Leaves are very thin to allow carbon dioxide to get into the leaf cells more easily.
2. RuBisCO is the most abundant plant protein.
3. Plants carry out respiration throughout the day and night like other living beings. Hence, they keep on emitting carbon dioxide all the time. Photosynthesis takes place only in the presence of light and hence, oxygen is released by plants only during the day.
