Across
- 3. using vesicles to transfer materials out of the cell.
- 4. the most basic structural, functional, and biological unit of all living organisms
- 5. any of a number of organized or specialized structures within a living cell.
- 6. all the cellular material inside the plasma membrane
- 11. movement of water across a membrane, high to low
- 14. the boundary of every cell, formed by a phospholipid bilayer and embedded with proteins, lipids, and carbohydrates
- 15. a protein that uses ATP to move sodium ions
- 17. molecules are too large to go through membrane
Down
- 1. a double-membraned organelle found in plant and algal cells that uses sunlight to produce energy-rich compounds, a process called photosynthesis
- 2. a complex of vesicles and folded membranes within the cytoplasm of most eukaryotic cells, involved in secretion and intracellular transport.
- 3. material coming into the cell - the membrane surrounds the material and pinches off to form a vesicle that moves through the membrane and into the cell
- 6. a rigid, protective outer layer found in plants, fungi, algae, bacteria, and archaea
- 7. the biological process of moving molecules across a cell membrane from an area of low concentration to an area of high concentration
- 8. membrane-bound cell organelles, often called the "powerhouses of the cell," responsible for generating the majority of the cell's chemical energy, adenosine triphosphate (ATP), by converting food into usable energy
- 9. movement of molecules through cell membrance
- 10. a network of membranous tubules within the cytoplasm of a eukaryotic cell, continuous with the nuclear membrane. It usually has ribosomes attached and is involved in protein and lipid synthesis.
- 12. a vital organelle in eukaryotic cells that contains the cell's genetic material (DNA) within a membrane-bound structure called the nuclear envelope
- 13. a space or vesicle within the cytoplasm of a cell, enclosed by a membrane and typically containing fluid.
- 16. genetic material
- 18. structures in the cytoplasm where proteins are made
