Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
In which organism(s) does photosynthesis occur?
A
plants
B
algae
C
some bacteria
D
all of these
Explanation: 

Detailed explanation-1: -In terms of organisms, photosynthesis occurs in autotrophes that contain the green pigment chlorophyll. This would include the entire plant kingdom, “half” of the Protista (the algae), & “half” the Moneran Kingdom (the blue-green algae). On the multicellular level, photosynthesis occurs in the leaves of plants.

Detailed explanation-2: -Plants, algae, and a group of bacteria called cyanobacteria are the only organisms capable of performing photosynthesis (Figure). Because they use light to manufacture their own food, they are called photoautotrophs (literally, “self-feeders using light”).

Detailed explanation-3: -Photosynthesis can only occur in specific cells of the plant that contain chlorophyll such as cells of leaves. Thus, all the cells of a plant can not perform photosynthesis.

Detailed explanation-4: -For photosynthesis to take place the organism must have chlorophyll. Since animal cells do not have chlorophyll photosynthesis does not take place in them.
