DENDROLOGY

Detailed explanation-1: -Photosynthetic cells are quite diverse and include cells found in green plants, phytoplankton, and cyanobacteria.

Detailed explanation-2: -Chlorophyll is found in virtually all photosynthetic organisms, including green plants, cyanobacteria, and algae. It absorbs energy from light; this energy is then used to convert carbon dioxide to carbohydrates.

Detailed explanation-3: -Plants, algae, and cyanobacteria, known as photoautotrophs, are the only organisms capable of performing photosynthesis.

Detailed explanation-4: -Green plants have the ability to make their own food. They do this through a process called photosynthesis, which uses a green pigment called chlorophyll.
