PATHOLOGY

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: -Plants. Plants are multicellular photosynthetic life forms. One of the major distinctive features of plants is the presence of chloroplasts containing chlorophyll systems that collect light energy from a light source to be converted into chemical energy through photosynthesis. They are autotrophic eukaryotes.
