Factor # 10. Protoplasmic Factors:

Content: A decline in rate was observed in higher concentrations. Blackman and his co-workers claimed that after an optimum concentration is reached, the rate of photosynthesis remains constant over a wide range of carbon dioxide concentrations. ADVERTISEMENTS: It has been demonstrated experimentally that at usual temperature and light intensities, artificial increase of carbon dioxide up to a concentration of 0.5 per cent may give an increased rate of photosynthesis, but only for a limited period. It appears that the high level of carbon dioxide is injurious to plants. Factor # 3. Water: Water is one of the raw material utilized in the process of photosynthesis. In land plants, the soil is the source of water. Only about one per cent or less of the water absorbed by the roots is actually used in photosynthesis.
