Cells

5. Network of proteins, such as microtubules and microfilaments, inside a eukaryotic cell that supports and shapes the cell
7. Interconnected network of thin, folded membranes that produce, process, and distribute proteins
10. Organelle that contains enzymes; digests old/worn out cell organelles
11. Organelles that link amino acids to form proteins
12. Cell that can be divided for long periods of time while remaining undifferentiated
13. Stack of flat, membrane-enclosed spaces containing enzymes that process , sort, and deliver proteins
15. Double-layer of phospholipids that form a boundary between the cell and the surrounding environment and controls the passage of materials into and out of a cell
17. Jelly-like substance inside cells that contains molecules and in some cell organelles
18. Inside the nucleus; makes ribosomes
20. Organelle that is used to store materials, such as water, food, or enzymes, that are needed by the cell.

1. Small cylinder-shaped organelle made of protein tubes arranged in a circle; aids mitosis
2. Cell that has a nucleus and other membrane-bound organelles
3. Small organelle that contains and transports materials within the cytoplasm
4. Organelle composed of numerous membranes that are used to convert solar energy into chemical energy; contains chlorophyll
6. Circular piece of genetic material found in bacteria that can replicate separately from DNA of the main chromosome
8. Cell that does not have a nucleus or other membrane-bound organelles
9. Bean-shaped organelle that supplies energy to the cell and has its own ribosomes and DNA; produces ATP
14. Long, continuous thread of DNA that consists of numerous genes and regulatory information
16. Organelle composed of a double membrane that acts as a storehouse for most of the cell’s DNA
19. Rigid structure that gives protection, support, and shape the cells in plants, algae, fungi, and bacteria
