Match organelles to their functions in animal and plant cells.
Classify cell structures as found in animal cells only, plant cells only, or both.
Explain how the structure of the red blood cell relates to its function.

Warm Up

Match each term to its definition

Draw a line connecting each organelle or structure on the left to its correct function on the right. Or write the matching letter next to each term.

Organelle / Structure	Your answer	Function
Nucleus		A. Provides a rigid outer layer that supports and protects the cell
Mitochondria		B. Contains the cell's genetic instructions (DNA)
Cell membrane		C. Controls what enters and leaves the cell
Cell wall		D. Releases energy from glucose for the cell to use
Chloroplasts		E. Stores water, salts and waste materials
Large central vacuole		F. Makes proteins for the cell
Ribosomes		G. Capture light energy and use it to make food (photosynthesis)
