Across
- 2. Membrane-enclosed organelle that is a system of sacs and tubes extending from the nuclear envelope. Smooth ER makes phospholipids, stores calcium, and has additional functions in some cells; ribosomes on the surface of rough ER make proteins.
- 5. Rigid but permeable structure that surrounds the plasma membrane of some cells.
- 6. Organelle that modifies proteins and lipids, then packages the finished products into vesicles.
- 8. Membrane-enclosed organelle; different kinds store, transport, or break down their contents.
- 9. Junction Cell Junction that forms a closable channel across the plasma membranes of adjoining animal cells.
- 12. Protein Type of energy-using protein that interacts with cytoskeletal elements to move the cell's parts or the whole cell.
- 13. This eukaryotic organelle specializes in producing ATP.
- 19. Reinforcing cytoskeletal element that functions in cell movement; a fiber of actin subunits .
- 22. Multifunctional network of membrane-enclosed organelles (endoplasmic reticulum, Golgi bodies, vesicles)
- 26. Structure that connects a cell to another cell or to extracellular matrix
- 27. In a cell a dense irregularly shaped region where ribosomal subunits are assembled.
- 28. Community of microorganisms living within a shared mass of secreted slime.
- 29. Small circle of DNA in some bacteria and archaea.
- 30. Barrel-shaped organelle from which microtubules grow.
- 31. Cell Junction that fastens together the plasma membrane of adjacent animal cells; collectively prevents fluids from leaking between the cells.
- 32. Organelle of protein synthesis.
- 33. Organelle of photosynthesis in the cells of plants and photosynthetic protists.
Down
- 1. Viscous fluid enclosed by the nuclear envelope.
- 3. Of a eukaryotic cell, organelle with a double membrane that holds the cell's DNA.
- 4. Large, fluid-filled vesicle that isolates or breaks down waste, debris, toxins, or food.
- 7. Enzyme-filled vesicle that breaks down cellular waste and debris
- 10. Enzyme-filled vesicle that breaks down fatty acids, Amino acids, and toxic substances.
- 11. Semifluid substance enclosed by a cell's plasma membrane.
- 14. A relationship in which the volume of an object increases with the cube of the diameter, and the surface area increases with the square.
- 15. Theory that all organisms consist of one or more cells, which are the basic unit of life; all cells come from division of pre-existing cells; and all cells pass hereditary material to offspring.
- 16. Membrane that encloses a cell and separates it from the external environment.
- 17. Cell Junction that fastens an animal cell to another cell, or to basement membrane. connect cytoskeletal elements inside the cell; Composed of adhesion proteins.
- 18. Matrix (ECM) Complex mixture of cell secretions; it's composition and function vary by cell type.
- 20. Long, slender cellular structure used for motility.
- 21. Structure that carries out a specialized metabolic function inside a cell.
- 23. Cytoskeletal element involved in movement; hollow filament of tubulin subunits.
- 24. Of a bacterium or archaeon, region of cytoplasm where the DNA is concentrated.
- 25. One of several types of double membranes organelles in plants and algal cells; for example, a chloroplast or amyloplast.
- 30. Network of protein filaments that support, organize, and move eukaryotic cells and their internal structures.
