Organisms that are made up of prokaryotic cells

Bacteria, archae and algae.

Structures found in the nucleus

Nucleolus, chromosomes, and DNA.

Which structure makes proteins using coded instructions that come from the nucleus?

Ribosomes

What structure contains digestive enzymes that break down food and old cell parts into molecules the cell can use?

Lysosomes

Which organelle converts the chemical energy stored in food into compounds that are more convenient for the cell to use?

Mitochondria

An organelle that help provide cells with energy

Mitochondria

First part of the cell theory

Basic building blocks of life

Second part of the cell theory

All life activities take places in cells.

Third part of the cell theory

New cells are produced in existing cells

What structures are found in plant cells, but not in animal cells?

Chloroplasts

Function of cytoskeleton

Helps maintain cell shape and cell motility. Internal movement is not possible without the _________.
