C — Chloroplasts
The green dots seen in leaf cells under a microscope are chloroplasts, the cell organelles that contain chlorophyll and are responsible for photosynthesis.
Chloroplasts are green-coloured plastids found in plant cells, especially in leaves. They appear as small green dots under a microscope. Mitochondria are colourless; vacuoles store cell sap; stomata are pores on leaf surface — none appear as green dots. Examiners expect direct identification of the organelle by its defining feature (green colour, photosynthesis).
