LIFE SCIENCE

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: -Plant chloroplasts are large organelles (5 to 10 m long) that, like mitochondria, are bounded by a double membrane called the chloroplast envelope (Figure 10.13). In addition to the inner and outer membranes of the envelope, chloroplasts have a third internal membrane system, called the thylakoid membrane.

Detailed explanation-3: -Mitochondria play host to one of the most important processes in your body, called cellular respiration. Taking in glucose and oxygen, mitochondria produce energy, which they capture and package as energy-rich molecules of ATP.

Detailed explanation-4: -Chloroplasts are small green, bean-shaped organelles. They are the sites of photosynthesis, allowing the plant to convert light (radiant) energy into chemical energy which is used to make food.
