• Chloroplast are discoid shaped green plastids which occur in all green parts of the plants. These are the actual sites of photosynthesis .

• When plants are grown in dark , etiolation ( destruction of chloroplast) occurs . The chloroplast align themselves (by their flat surface ), parallel to the walls of mesophyll cells under optimum light intensities.

• They change their position in perpendicular to walls of the mesophyll cells where the intensity of light of high. chloroplasts contains their own dna , hence , termed as semiautonomous organelle.
