Chloroplast
  1. In plants, chloroplasts are the essential organelles for carrying out photosynthesis.
  2. Chloroplasts are found in all green plants.
  3. Chloroplast occurs mainly in the mesophyll cells of leaves.
  4. Typical chloroplasts are disc shaped.They are covered by two membranes.
  5. Chloroplasts are filled with colourless area called stroma.
  6. Stacks of thylakoid membranes (called grana) are located in the stroma and are connected by stroma lamellae.
  7. The chlorophyll and other pigments of the chloroplast are fat soluble and are located in the lipid part of the thylakoid membrance.
  8. Chlorophyll and other accessory pigment molecules are situated in the thylakoid membranes and organized to form the reaction centres called photosystem I and photosystem II.
