Cell Biology

5. category of a cell without a membrane-bound nucleus: archaea and bacteria
11. organelle embedded with ribosomes. It modifies and transports proteins WITHIN the cell.
13. "packets" of RNA that are the site of protein synthesis. It is the organelle involved in protein synthesis.
14. membrane-bound organelle found in eukaryotes that contains DNA; it is the site of replication and transcription.

1. a network of lipids and proteins that forms the boundary between a cell’s contents and the outside of the cell.
2. organelle that helps break down food/worn out parts.
3. thick, jelly-like material which contains and supports cell organelles
4. an organelle found in large numbers in most cells, in which the biochemical processes of respiration and energy production occur. It has a double membrane, the inner layer being folded inward to form layers (cristae).
6. category of a cell that has a membrane-bound nucleus: animals and plants
7. organelle that uses the sun's energy to produce food in the form of sugar, contains a green substance called chlorophyll.
8. a complex of vesicles and folded membranes within the cytoplasm of most eukaryotic cells, involved in secretion and intracellular transport. It is stacks of flattened sacs, and it packages and transports proteins.
9. a self-replicating cylindrical organelle that is involved in the process of nuclear division.
10. a thick, rigid wall that surrounds each cell, supports cell and helps plant keep shape.
12. cell organelle that stores materials such as water, salts, proteins, and carbohydrates in plants.
