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: -Most plants, algae, and cyanobacteria perform photosynthesis; such organisms are called photoautotrophs. Photosynthesis is largely responsible for producing and maintaining the oxygen content of the Earth’s atmosphere, and supplies most of the energy necessary for life on Earth.

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: -Photosynthesis occurs only in some bacteria such as cyanobacteria, which is a diverse group of cyanobacteria. They are also known as blue-green bacteria. In higher-order plants, photosynthesis occurs in the chloroplast. Bacteria do have chloroplasts.
