Sacs bound by a single membrane that contain enzymes to break down large molecules or damaged organelles. Found in animal cells only.

The site of cellular respiration that produces an energy rich molecule called ATP

Small structures free in the cytoplasm or associated with the endoplasmic reticulum that carry out protein synthesis (make proteins)

Stores, modifies and packages proteins for export from the cell

The area where DNA resides that directs the activities of the cell

A region inside the cell where the organelles occur

Storage organelles that are membrane bound and have many possible functions

Rigid outer layer of a plant cell

Captures energy from the sun and uses it to produce organic molecules through photosynthesis in plant cells

Found inside the nucleus and produces ribosomes
