Across
- 2. The organelle in eukaryotic cells that modifies many proteins and packages them into small, bubble-like structures called vesicles
- 5. The usually membrane surrounded structure found inside a eukaryotic cell that perform special functions
- 7. Allowing some substances to pass while keeping others out
- 8. The movement of molecules through a membrane as a result of a concentration gradient
- 11. A small structure that assembles proteins found in both prokaryotic and eukaryotic cells
- 13. A protein that speeds up chemical reactions
- 15. The movement of molecules across a membrane without the cell doing any work as in osmosis and diffusion
- 18. A structure that contains a cell's DNA
- 19. A group of tissues that work together
- 20. The molecule that contains the information for making the different proteins that have different jobs to do
- 21. The molecule that a cell uses to power many processes in the cell and need chemical energy
- 23. The material inside of a cell excluding the nucleus
- 25. A whip like structure that some cells use to propel themselves through their environment
- 26. A small organelle in eukaryotic cells that act as the demolition crew within the cell
- 27. The organelle in eukaryotic cells that makes most of the cell's ATP energy
- 28. The difference in the number of a certain type of particles (Such a K ions) on each side of a membrane
- 29. A group of similar cells that work together
- 30. The green pigment that absorbs sunlight for photosynthesis
- 31. The structure that surrounds all cells and regulates what comes in and goes out
Down
- 1. The model of the cell that states that cells make up all living things, come from preexisting cells and perform the functions of living things
- 3. Describes a process that does not use oxygen
- 4. A rigid structure that surrounds and protects some cells not all
- 6. The process in organisms of breaking down molecules of glucose to make ATP
- 9. The movement of molecules across a membrane that requires the use of work (uses energy)
- 10. The movement of water across a semipermeable membrane
- 12. Several types of long and thin fibers anchored to various parts of the cell that the help the cell maintain and change its shape
- 14. A slimy layer surrounding some bacteria that protects them from harmful substances and prevents them from drying out
- 16. A special cell that divides and matures into any type of cell needed by the body
- 17. A network of tubes in eukaryotic cells that help produce and transport proteins and other molecules throughout the cell
- 22. The process by which a plant uses energy from the sun to turn carbon dioxide and water into glucose
- 24. An organism that can make its own food typically through photosynthesis
