   (i) X is a PLANT cell — because it has a cell wall, chloroplasts and a large central vacuole (features absent in animal cells). Y is an ANIMAL cell — because it lacks a cell wall and chloroplasts. (ii) Mitochondria are the site of aerobic respiration — they release energy (ATP) from glucose for cell activities. (iii) Photosynthesis occurs in the chloroplast.
