Options

A. all bacteria, fungi and algae
B. fungi, algae nd green plant cells
C. some bacteria, algae and green plant cells
D. viruses, fungi and bacteria

Answer

C

Explanation

(c) Some photosynthetic bacteria such as Rhodopseudomonas can prepare carbohydrates. But during thes type of food synthesis `O_(2)` is not evolved because , in this case hydrogen donor is other than `H_(2)O`. Algae (green and blue-green) and all green plant cells prepare their food (carbohydrate) through photosynthesis. Here, hydrogen ions are donated by water molecules by the process of photolysis of water, i.e. `O_(2)` is released during thes type of food synthesis.
