Question

A student observes a small disc-like green organelle in a plant cell. Which organelle is the student most likely viewing?

mitochondria

vacuole

Golgi apparatus

chloroplast

Answer 1

The student is most likely observing a chloroplast within the plant cell.

Answer 2

Answer: Chloroplast

The plant cells have only one type of green colored organelles, that is chloroplast. This is because the green color is imparted by the green colored pigment- chlorophyll. Also, these organelles are disc-shaped, stacked in a bundle. Mitochondria, vacuole and golgi apparatus are different in shape, as compared to chloroplast.
