A) All bacteria, fungi and algae
B) Fungi, algae and green plant cells
C) Some bacteria, algae and green plant cells
D) Viruses, fungi and bacteria
Correct Answer: C
Solution :
[c] Some photosynthetic bacteria such as Rhodopseudomonas can prepare carbohydrates. But during this type of food synthesis \[{{O}_{2}}\] does 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 after molecules by the process of photolysis of water, i.e., \[{{O}_{2}}\] is released during this type of food synthesis.
