    Ø  Specialty  of animal cell:

1) There is no any cell well.

2) There is no any plastid.

3) There is present centrism all time.

4) Some of lowest animal have central vacuole.

5) Golgi body seen by microscope.

6) Collected food of animal cell is mainly glycogen.

    Ø  Specialty  of plant cell:

1) There are present cell well which is made of cellulose.

2) There are present varieties kinds of plastid.

3) There is no centrism in plant cell.

4) There is present one more central vacuole.

5) Golgi body seen by microscope rear.

6) Collected food of plant cell is starch.
