Cell Biology

3. membrane-bound organelle found in eukaryotes that contains DNA; it is the site of replication and transcription.
5. a self-replicating cylindrical organelle that is involved in the process of nuclear division.
7. thick, jelly-like material which contains and supports cell organelles
9. organelle that has no ribosomes. It aids in making and transporting lipids and breaking down toxic substances.
10. category of a cell without a membrane-bound nucleus: archaea and bacteria
11. 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).
13. a thick, rigid wall that surrounds each cell, supports cell and helps plant keep shape.
14. a network of lipids and proteins that forms the boundary between a cell’s contents and the outside of the cell.
15. organelle that helps break down food/worn out parts.

1. cell organelle that stores materials such as water, salts, proteins, and carbohydrates in plants.
2. organelle embedded with ribosomes. It modifies and transports proteins WITHIN the cell.
4. "packets" of RNA that are the site of protein synthesis. It is the organelle involved in protein synthesis.
6. organisms with membrane-bound nuclei
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.
12. uses the sun's energy to produce food in the form of sugar, contains a green substance called chlorophyll.
