Eukaryotic cells contain organelles, each of

which has specific functions

Plant vacuoles

Mitochondria

Chloroplast

Both plant and animal cells

contain mitochondria; animal

cells do not have chloroplasts.

Cytoskeleton

Nucleus

Both plant and animal cells have

cytoskeletons. Plants (and fungi) also

have a cell wall for structural support.

Chloroplasts contain chlorophyll and

infrastructure that supports the production

of energy from captured sunlight.

Plant vacuoles

perform the same

functions that

lysosomes do in

animal cells. The

central vacuole

contains water and

aids in maintaining

the cell’s rigidity.
