GENERAL HISTOLOGY

Detailed explanation-1: -In plants and algae, which developed much later, photosynthesis occurs in a specialized intracellular organelle-the chloroplast. Chloroplasts perform photosynthesis during the daylight hours. The immediate products of photosynthesis, NADPH and ATP, are used by the photosynthetic cells to produce many organic molecules.

Detailed explanation-2: -Mitochondria (singular, mitochondrion) are often called the powerhouses or energy factories of the cell.

Detailed explanation-3: -Chloroplasts are specialized organelles that are only found in plant cells. Chloroplasts contain thylakoids. Thylakoids are the specific structures responsible for photosynthesis.

Detailed explanation-4: -The Two Parts of Photosynthesis Photosynthesis takes place in two stages: the light-dependent reactions and the Calvin cycle. In the light-dependent reactions, which take place at the thylakoid membrane, chlorophyll absorbs energy from sunlight and then converts it into chemical energy with the use of water.

Detailed explanation-5: -Answer and Explanation: The plant cell performs the process of photosynthesis via the specialized organelle called the chloroplast. Chloroplasts are the structures that contain specialized pigments called chlorophyll. Chlorophyll is the green pigment present in plants that mediates the photosynthesis process.
