Inventions and Discoveries in Physics.

Plant CellAnimal Cell
A plant cell has a rigid wall on the outside.Cell wall is absent.
It is usually larger in size.An animal cell is comparatively smaller in size
It cannot change its shapeAn animal cell can often change its shape
Plastids are found in plant cells.Plastids are usually absent.
Plant cells exposed to sunlight possess chlorophyll containing plastids called chloroplasts. Chlorophyll is absent
A mature plant cell contains a large central vacuole.An animal cell often possesses many small vacuoles.
Nucleus lies on one side in the peripheral cytoplasm.Nucleus usually lies in the center.
Mitochondria are comparatively fewer.Mitochondria are generally more numerous.
Cristae are tubular in plant mitochondria.Cristae are plate - like in animal mitochondria.
Plant cells do not burst if placed in hypotonic solution due to the presence of cell wall. Animal cells usually burst if placed in hypotonic solution unless and until they possess contractile vacuoles.
Centrioles are usually absent except in lower plants.Centrioles are found in animal cells.
Golgi apparatus consists of a number of distinct or unconnected units called dictyosomes.Golgi apparatus is either localized or consists of a well connected single complex.
Lysosomes are rare. Their activity is performed by specialized vacuoles. Typical lysosomes occur in animal cell.
Glyoxysomes may be present.They are absent.
Crystals of inorganic substances may occur inside the cell.Crystals usually do not occur in animal cells.
Reserve food is generally starch and fat.Reserve food is usually glycogen and fat.
Adjacent cells may be connected through plasmodesmata.Adjacent cells are connected through a number of junctions.
