HORTICULTURE

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.

Detailed explanation-2: -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-3: -Explanation: For photosynthesis to occur in a cell, the cell must have chlorophil. Such cells are found in the plants, algae & certain bacteria to harness energy from sunlight & turn it into chemical energy.

Detailed explanation-4: -The primary cellular structures that ensure photosynthesis takes place are chloroplasts, thylakoids and chlorophyll. Photosynthesis takes place inside the chloroplasts that sit in the mesophyll of the leaves.

Detailed explanation-5: -During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose.
