Cell Structure and Function

2. Helps the cell maintain its shape and involved in movement.
7. The portion of the cell outside the nucleus.
10. Large sack that stores water, salts, and organic molecules.
12. Produce proteins by following coded instructions from DNA.
14. Endoplasmic Reticulum is a internal membrane system where lipids and __________ are assembled.
15. Lipid ____________ is what a cell membrane consists of.
18. Contains the same concentrations of solute.
21. ___________________ apparatus is an organelle that modifies, sorts and packages proteins.
22. Contains tubulins and helps organize cell division in animal cells.
23. An organ ___________ a group of organs that work together to perform essential tasks.
24. Cell ______________ is a thin flexible barrier surrounding all cells.
25. Higher concentration of solute causing cells to shrink.
26. _______________ permeable is when the cell membrane allows some substances pass through, but not others.
28. Cells that enclose their DNA in nuclei.

1. The Powerhouse of the cell, converts chemical energy into usable energy.
3. Uses enzymes to break down large molecule that are no longer useful.
4. _____________ diffusion is when special protein channels are used to move molecules across the membrane.
5. ______________is the facilitated diffusion of water through a selectively permeable membrane.
6. Lower concentration of solute causing cells to swell.
8. The process in which particles move from high to low concentration without using energy.
9. Cells that do not enclose their DNA in nuclei
11. ______________organisms maintain homeostasis by growing, responding to environment, transforming energy, reproducing.
13. Structures that have specialized functions in eukaryotic cells.
16. A group of tissues working together to perform essential tasks.
17. The process of converting sunlight into food for plant cells.
19. The basic unit of life.
20. A large membrane-enclosed structure that contains DNA.
27. Cell__________ comes from discoveries by German scientists Schleiden, Schwann and Virchow.
29. Used to respond to a chemical signal, to which the signaling molecule can bind to.
30. A group of similar cells that perform a particular function.
