Both plant and animal cells are eukaryotic i.e. they contain a nucleus and organelles, and are enclosed by a plasma membrane. Protozoa, fungi, plants and animals have Eukaryotic cells.
Plant cells are unique among eukaryotic cells for several reasons. For maintenance of structural support, plants have reinforced, relatively thick cell walls that are made mostly of cellulose and help. Where animal cells do not have such structures, they have only a plasma membrane.
For storage and maintaining the shape of the cell, plant cell contains a large, singular vacuole. In contrast, animal cells have many, smaller vacuoles.
Both plant and animal cells have mitochondria, but only cells of plant have chloroplasts. They don’t create their sugar from food eating, so they need to make sugar from sunlight. This process (photosynthesis) takes place in the chloroplast.
