DENDROLOGY

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: -Chloroplasts are plant cell organelles that convert light energy into relatively stable chemical energy via the photosynthetic process.

Detailed explanation-3: -Chloroplasts produce energy through photosynthesis and oxygen-release processes, which sustain plant growth and crop yield.

Detailed explanation-4: -Mitochondria are tiny organelles inside cells that are involved in releasing energy from food. This process is known as cellular respiration. It is for this reason that mitochondria are often referred to as the powerhouses of the cell.
