The following points highlight the two main types of photosynthetic pigments. The types are: 1. Chlorophylls 2. Carotenoids. Type # 1. Chlorophylls: They are the green photosynthetic pigments. Five types of chlorophylls occur in plants other than bacteria— a, b, c, d and e. Out of these only two chlorophylls occur in the chloroplasts of higher plants, a and b. [...]
The following points highlight the four main raw materials used in photosynthesis. The types are: 1. Carbon Dioxide 2. Water 3. Light 4. Chloroplasts. Raw Material: Type # 1. Carbon Dioxide: In land plants, carbon dioxide is obtained from the atmosphere through the stomata. Small quantities of carbonates are also absorbed from the soil through the roots. Hydrophytes get their [...]
