Function
nucleus
Directs a cell’s activities
Cell membrane
Holds a cell together and separates it from its surroundings. It
can be found in both plant and animal cells.
Cell wall
Supports and protects a plant cell.
cytoplasm
chloroplast
A jellylike substance containing chemicals that help the cell stay
healthy.
Makes food for a plant cell.
vacuole
Stores food, water, or wastes.
mitochondrion
Releases energy from food.

The four types of tissue and what they do. P.244-245
o Epithelial tissue - skin, lines internal organs, lines the walls of blood vessels
o Muscle tissue - Most of the body is made up of muscle tissue. Whenever you move,
muscle tissue contracts and relaxes.
o Connective tissue – bones, cartilage, blood
o Nervous tissue – helps you think, talk, walk, and see. It is found in the brain, spinal cord,
and nerves.
Multi-celled organisms are made up of trillions of cells. Each cell carries out its own specific job.
They work together to make tissues, organs, and organ systems. A single-celled organism
functions differently. They don’t have organs or tissues. The one cell has to eat, move, and do all
the other functions necessary for survival.
The circulatory system’s main function is to carry materials, such as food and oxygen, to the cells
throughout the body.
