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, the organelles responsible for photosynthesis, are in many respects similar to mitochondria. Both chloroplasts and mitochondria function to generate metabolic energy, evolved by endosymbiosis, contain their own genetic systems, and replicate by division.

Detailed explanation-3: -A chloroplast is a type of plastid (a saclike organelle with a double membrane) that contains chlorophyll to absorb light energy.

Detailed explanation-4: -Parts of the chloroplast Thylakoids are disc-shaped and collect photons from a light source (usually the sun). They consist of a thylakoid membrane that surrounds the lumen. The lumen is where processes like oxygen evolution, plastocyanin-mediated electron transfer, and photoprotection occur during photosynthesis.
