Cell Processes

3. The diffusion of water through a selectively permeable membrane
7. A process by which a cell takes material into the cell by infolding of the cell membrane
10. Organelle that is found in the cells of plants and some other organisms that captures the energy from sunlight and converts it into chemical energy (photosynthesis)
12. The movement of specific molecules across cell membranes through protein channels
14. A tiny, nonliving particle that invades cells and reproduces while inside of them
15. The fluid portion of cytoplasm
18. The idea that all living things are composed of cells, cells are the basic units of structure and function in living things, and new cells are produced from existing cells
20. A thin, flexible barrier around the cell that regulates what enters and leaves the cell
21. A tiny opening or pore that is used for gas exchange
22. The basic unit of structure and function in living things
23. The movement of molecules from an area of higher concentration to an area of lower concentration

1. A type of cell that lacks a membrane-enclosed nucleus and membrane-enclosed organelles; these cells can be found only in the domains Bacteria and Archaea
2. Having the same solute concentration as another solution
4. The movement of substances through the cell membrane without using any energy
5. A rigid layer of nonliving material that surrounds the cells of plants and some other organisms
6. A type of cell with a membrane-enclosed nucleus and membrane-enclosed organelles. Protists, plants, fungi, and animals all are made up of Eukaryotic cells
8. Having a higher concentration of solute than another solution
9. A long, whip-like structure that allows a cell to move
11. The movement of substances through a cell membrane using energy
13. Cytoplasmic organelle where proteins are created
16. A cell organelle that stores materials such as water, salts, waste, proteins, and carbohydrates
17. A process by which a cell releases large amounts of material
19. A small ring of DNA that carries accessory genes separate from those of the bacterial chromosome
