Breanna Reynosa Cell Structure
Across
- 2. in eukaryotic cells, all cellular contents outside the nucleus; in prokaryotic cells, all of the cells' contents
- 4. cell organelle consisting of RNA and protein found throughout the cytoplasm in a cell; the site of protein synthesis
- 7. property of biological membranes that allows some substances to pass across it while others cannot; also called semipermeable membrane
- 12. 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
- 13. specialized structure that performs important cellular functions within a cell
- 14. cell organelle that converts the chemical energy stored in food into compounds that are more convenient for the cell to use
- 15. unicellular organism that lacks a nucleus
- 16. organelle found in cells of plants and some other organisms that captures the energy from sunlight and converts it into chemical energy
- 17. thin, flexible barrier that surrounds all cells; regulates what enters and leaves the cell
- 18. cell organelle that stores materials such as water, salts, proteins, and carbohydrates
Down
- 1. cell organelle that breaks down lipids, carbohydrates, and proteins into small molecules that can be used by the rest of the cell
- 3. flexible double-layered sheet that makes ups the cell and forms a barrier between the cell and its surroundings
- 5. the center of an atom, which contains the protons and neutrons; in cells, the structure that contains the cell's genetic material in the form of DNA
- 6. basic unit of all forms of life
- 8. organism whose cells contain a nucleus
- 9. internal membrane system found in eukaryote cells; place where lipid components of the cell membrane are assembled
- 10. network of protein filaments in a eukaryotic cell that gives the cell its shape and internal organization and is involved in movement
- 11. organelle in cells that modifies, sorts, and packages proteins and other material from the endoplasmic reticulum for storage in the cell or release outside the cell
- 12. strong, supporting layer around the cell membrane in some cells
