Across
- 1. Specialized structure that preforms important cellular functions within a eukaryotic cell
- 6. process by which molecules tend to move from one area where they are more concentrated to one where they are less
- 12. energy requiring process that moves materials across a cell membrane against a concentration difference
- 14. separate roles for each type of cells in multicellular organisms
- 16. when comparing two solutions, the solution with the lesser concentration of the solutes
- 19. cell organelle filled with enzymes needed to break down certain materials in the cell
- 21. process by which a cell takes material into the cell by infolding of the cell membrane
- 22. One of two tiny structures located in the cytoplasm of animal cells near the nucleus envelope
- 24. material inside the cell membrane-not including the nucleus
- 25. internal membrane system in cells in which lipid components of the cell membrane are assembled and some proteins are modified
- 26. network of protein filaments within some cells that helps the cell maintain its shape and is involved in many forms of cell movement
- 28. system group of organs that work together to preform a specific function
- 29. collection of living matter, basic unit of life
- 30. process in which extensions of cytoplasm surround and engulfs large particles and take them into the cell
- 33. when comparing two solutions, the solution with the greater concentration of the solutes

Down
- 2. double layered sheet that forms the core of nearly all cell membranes
- 3. Small particle in the cell on which proteins are assembled, made up of RNA and protein
- 4. cell organelle that stores materials such as water, salts, proteins, and carbohydrates
- 5. stack of membranes in the cell that modifies, sorts, and packages from the endoplasmic reticulum
- 7. movement of specific molecules across cell membranes through protein channels
- 8. when the concentration of a solute is the same throughout a solution
- 9. cell organelle that converts the chemical energy stored in food into compounds that are more convenient for the cell to use

- 22. The mass of solute in a given volume of solution
- 23. organelle found in cells of plants and some other organisms that capture energy from sunlight and convert it into chemical energy
- 26. granular material visible within the nucleus, consists of DNA tightly coiled around proteins
- 27. Small dense region within the most nuclei in which the assembly of proteins begins
- 30. single-celled organism lacking a nucleus
- 31. organism whose cells contains a nucleus
- 32. process of which a cell releases a large amount of material
- 34. The center of the atom which contains the protons and neutrons
