Across
- 3. Organism whose cells contain a nucleus
- 8. Cell organelle that stores materials such as water, salts, protein, carbohydrates
- 10. Property of biological membranes that allows some substances to pass across it while others cannot; also called semi permeable membrane
- 11. Organelle found in cells of plants and some other organisms that captures the energy from sunlight and converts it into chemical energy
- 12. Organelle in cells that modifies, sorts, and packages proteins and other material from the endoplasmic reticulum for storage in the cell or release outside of the cell
- 13. Thin, flexible barrier that surrounds all cells; regulates what enters and leaves the cell
- 14. cell organelle that converts the chemical energy stored in food into compounds that are more convenient for the cell to use
- 16. Flexible double-layered sheet that makes up the cell membrane and forms a barrier between the cell and its surroundings
Down
- 1. The center of an atom, which contains the protons and neutrons in cells, the structure that contains the cells’ genetic material in the form of DNA
- 2. Unicellular organism that lacks a nucleus
- 4. Cell organelle that breaks down lipids, carbohydrates, and proteins into small molecules that can be used by the rest of the cell
- 5. Fundamental concept of biology that states that all living things are composed of cells; that cells are the basic units of structure and function in living things; and that new cells are produced from existing cells
- 6. Strong, supporting layer around the cell membrane in some cells
- 7. Basic unit of all forms of life
- 9. Network of protein filaments in a eukaryotic cell that gives the cell its shape and internal organization and is involved in movement
- 15. In eukaryotic cells, all cellular contents outside the nucleus; in prokaryotic cells, all the cells’ contents
