Across
- 3. They are primarily responsible for locomotion, either of the cell itself or of fluids on the cell surface.
- 5. any cell or organism that possesses a clearly defined nucleus.
- 6. (ER), Golgi apparatus, and lysosomes. Vesicles also allow the exchange of membrane components with a cell's plasma membrane.
- 9. is the basic unit of lifeāthe building block for all plants and animals on the planet.
- 13. are complex cellular structures found in all cells and are responsible for making proteins.
- 14. are plant cell organelles that convert light energy into relatively stable chemical energy via the photosynthetic process.
- 15. is a thick solution that fills each cell and is enclosed by the cell membrane. It is mainly composed of water, salts, and proteins.
- 16. called chloroplasts allow plants to capture the energy of the Sun in energy-rich molecules.
Down
- 1. are hairlike structures,made primarily of protein, found on the surfaces of cells and used for movement by microorganisms.
- 2. are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell's biochemical reactions.
- 4. apparatus found in plant cells are called dictyosomes-Dictyosomes refers to stacks of flat, membrane-bound cisternae which together.
- 7. are membrane bounded organelles found in animal and plant cells. They assist with degrading material taken in from outside the cell and life expired components from within the cell.
- 8. is a biological membrane that separates the interior of all cells from the outside environment which protects the cell from its environment.
- 10. is a unicellular organism that lacks a nuclear membrane-enclosed nucleus.
- 11. wall is a structural layer surrounding some types of cells, just outside the cell membrane.
- 12. is a highly specialized organelle that serves as the information and administrative center of the cell.
