Cell Unit

6. organelle in cells that modifies, sorts, and packages proteins and other materials from the endoplasmic reticulum for storage in teh cell or release outside the cell
7. 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
8. structure in an animal cell that helps to organize cell division
9. the movement of ions or molecules across a cell membrane into higher concentration, assisted by enzymes and requiring energy.
11. when comparing two solutions, the solution with the greater concentration of solutes
12. process by which particles tend to move from an area where they are more concentrated to an area where they are less concentrated
15. internal membrane system found in eukaryotic cells; place where lipid components of the cell membrane are assembled
17. organelle found in cells of plants and some other organisms that captures the energy from sunlight and converts it into chemical energy
18. when the concentration of two solutions is the same
19. strong, supporting layer around the cell membrane in some cells; primarily producers

1. thin, flexible barrier that surrounds all cells; regulates what enters and leaves the cell
2. network of protein filaments in a eukaryotic cell that gives the cell its shape and internal organization and is involved in movement
3. in eukaryotic cells, all cellular content outside the nucleus; in prokaryotic cells, all the cells' contents
4. relatively constant internal physical and chemical conditions that organisms maintain
5. process of diffusion in which molecules pass across the membrane through cell membrane channels
10. when comparing two solutions, the solution with the lesser concentration of solutes
13. compound made up of carbon, hydrogen, and oxygen atoms; type of nutrient that is the major source of energy for the body
14. organism whose cells contain a nucleus
16. basic unit of all forms of life
20. macromolecule made mostly from carbon and hydrogen atoms; includes fats, oils, and waxes
