DENDROLOGY

Detailed explanation-1: -Photosynthesis occurs in the chloroplasts, whereas cellular respiration occurs in the mitochondria. Photosynthesis makes glucose and oxygen, which are then used as the starting products for cellular respiration.

Detailed explanation-2: -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-3: -Photosynthesis occurs only in the chloroplasts of a cell. Cellular respiration is the opposite process where plants and animals break down oxygen and glucose into water, carbon dioxide, and ATP used for energy. Cellular respiration happens in the mitochondria of both plants and animals.

Detailed explanation-4: -While most aerobic respiration (with oxygen) takes place in the cell’s mitochondria, and anaerobic respiration (without oxygen) takes place within the cell’s cytoplasm.
