3. _________ apparatus: modifies, sorts and packages proteins / other materials from the E.R. for storage or shipment
4. ___________ permeable, property allowing some substances to pass across while others cannot pass
5. network of protein filaments that gives the cell its shape and internal organization, also helps in movement
6. breaks down lipids, carbohydrates and proteins into small molecules that can be used by the cell
9. strong, supporting layer around the cell membrane in some cells
11. fluid portion of the cell outside the nucleus
12. specialized structure that performs important cellular functions within a eukaryotic cell

1. stores materials such as water, salts, proteins and carbohydrates
2. cell organelle consisting of RNA and protein found in the cytoplasm; site of protein synthesis
5. found in cells of plants, captures energy from sunlight and convers it into chemical energy
7. ____________ reticulum, internal membrane system where lipid parts of a cell are assembled
8. converts chemical energy in food into compounds that cell can use "powerhouse"
10. flexible double-layered sheet that makes up the cell membrane and forms a barrier between cell and surroundings
