eukaryotic cells: are complex cells with many organelles and other structures in the cell.
5.Plant cells have a cell wall in addition to their cell membranes while animal cells only have a surrounding membrane.
Both plant and animal cells have vacuoles but they are much larger in plants, and there is generally only 1 vacuole in plant cells while animal cells will have several, smaller ones.
6.PLASMA MEMBRANE/ CELL MEMBRANE
CYTOPLASM.
NUCLEUS.
