The chloroplasts of non-Archaeplastida eukaryotes have three or four membrane layers.Temporal cell organelles: they are only found at specific stages of the cell’s life cycle – chromosome, centrosome, autophagosome, and endosome. 3. Cell type specific cell organelles: they only exist in the plant cells – chloroplast, central vacuole, and cell wall. Many unique cell organelles/structures only exist in specific cell types.

Photosynthesis occurs in the chloroplast, an organelle specific to plant cells. The light reactions of photosynthesis occur in the thylakoid membranes of the chloroplast. Electron carrier molecules are arranged in electron transport chains that produce ATP and NADPH, which temporarily store chemical energy.
