cell
osmosis
cellular respiration
organ
nucleus
organelles
organ system
diffusion
cytoplasm
tissue
1. Osmosis is the diffusion of water across a membrane.
2. Organelles are structures that perform specific functions in a cell.
3. Diffusion is a process that spreads substances through a gas or liquid.
4. The cytoplasm is a thick fluid between the nucleus and cell
membrane.
5. The nucleus is the cell part that directs the activities of the cell.
6. The process of breaking down glucose in cells is called cellular
respiration.
7. A group of related organs that work together to perform a specific
function is an organ system.
8. A cell is the basic unit that makes up living things.
9. A group of similar specialized cells is a tissue.
10. An organ is a group of related tissue that performs a specific
function.
11. What are four reasons that cells need energy?
Cells need energy for movement, cell division, making proteins,
and moving materials (waste).
12. What happens in cellular respiration?
In cellular respiration glucose and oxygen are changed into
carbon dioxide (gas) and water. This releases a lot of energy that
is trapped in ATP (Adenosine TriPhosphate molecule).
13. Name the parts of cell organization in the correct order.
(Organism, organs, tissues, cell, and organ systems)
Organism

14. Be sure to know what active and passive transport looks like.
Be able to explain the difference. (Look on page 19 in your science
book.)
15. Label the parts of the cell.
