LS Ch 2 Cell Structure

4. Organelle in eukaryotic cells that makes most of the cell's ATP
6. membrane surrounded structure in eukaryotic cells that have specific functions
7. Small structure that assembles proteins found in both prokaryotic and eukaryotic cells
8. Group of similar cells that work together
10. Jelly-like material inside of a cell
13. Slimy layer surrounding some bacteria that protects them from harmful substances
14. Smallest working unit of an organism
16. Process in organisms of breaking down molecules to produce ATP
17. Whip-like structure that some cells use to propel themselves through their environment
18. Group of tissues that work together
22. Movement of molecules across a membrane without the cell doing any work
23. molecule a cell uses to power many processes in the cell that need chemical energy
24. describes a process that does not use oxygen
26. Protein that speeds up or slows down chemical reactions
27. Structure that contains a cell's DNA
28. plants use energy from the sun to turn carbon dioxide and water into glucose

1. Organelle in eukaryotic cells that modifies many proteins and packages them into vesicles
2. Network of tubes in eukaryotic cells that produce and transport proteins
3. Organism that can make its own food, typically through photosynthesis
5. Structure that surrounds all cells and regulates what comes in and goes out
9. long and thin fibers anchored to various parts of the cell that help maintain its shape
11. Small organelle in eukaryotic cells that act as the demolition crew within a cell.
12. Rigid structure that surrounds and protects some cells
14. Green pigment that absorbs sunlight for photosynthesis
15. Molecule that contains important information for making proteins and regulating cellular processes
16. Model of the cell that states cells make up all living things
19. Movement of molecules across a membrane that requires the cell to do work
20. Movement of molecules through a membrane as a result of a concentration gradient
21. describes a process that uses oxygen
25. Movement of water across a semipermeable membrane
