Except the protozoan Euglena, no animal cell possesses plastids.
Vacuoles in animal cells are many, small and temporary.
Animal cells have a single highly complex and prominent Golgi apparatus.
Animal cells have centrosome and centrioles.
PLANT CELL
Plant cells are larger than animal cells.
The plasma membrane of plant cells is surrounded by a rigid cell wall of cellulose.
They have Plastids
Most mature plant cells have a permanent and large central sap vacuole.
Plant cells have many simpler units of Golgi apparatus, called dictyosomes.
Plant cells lack centrosome and centrioles.
Hope this helps!
