Chloroplasts are a type of membrane-bound plastids that contain a network of membranes embedded into a liquid matrix and harbor the photosynthetic pigment called chlorophyll. It is this pigment that imparts a green color to plant parts and serves to capture light energy....

Answer:

Function of chloroplast are

  1. Chloroplasts are the sites for photosynthesis, which comprises a set of light-dependent and light-independent reactions to harness solar energy and convert it into chemical energy.
  2. The components of chloroplast participate in several regulatory functions of the cell as well as in photorespiration.
  3. Chloroplasts also provide diverse metabolic activities for plant cells, including the synthesis of fatty acids, membrane lipids, isoprenoids, tetrapyrroles, starch, and hormones.
  4. Plants lack specialized immune cells—all plant cells participate in the plant response.
  5. The chloroplasts with the nucleus and cell membrane and ER are the key organelles of pathogen defense.
  6. Chloroplasts can serve as cellular sensors

Structure of chloroplast are.

  1. Chloroplasts found in higher plants are generally biconvex or planoconvex shaped.
  2. In different plants, however, chloroplasts may have different shapes, varying from spheroid, filamentous saucer-shaped, discoid or ovoid-shaped.
  3. They can be found in the cells of the mesophyll in plant leaves. They are vesicular and have a colorless center.
  4. The average size of the chloroplast is 4-6 µ in diameter and 1-3 µ in thickness.
