Cell Structure and Function

2. surrounds the organelles
3. degrades hydrogen peroxide
7. an example is bacteria
8. Apparatus, receives proteins from the rER and distributes them to other organelles or out of the cell (receiving, processing, packaging, and shipping)
9. ER, involved in the synthesis of lipids and breakdown of toxic substances (not covered with ribosomes)
11. concluded that all animals are made of cells
12. determined that cells come from only other cells
13. used for temporary storage of wastes, nutrients, and water
15. invented first microscope and observed "little boxes" which he called cells in cork
20. the first person to observe living cells
22. and Flagella, cell motility
23. only in plant cells and where photosynthesis happens
24. do not have a nucleus and are more simple

1. breaks down food particles, invading objects, or worn out cell parts
4. have a nucleus and are more complex
5. Reticulum, intercellular highway
6. ER, prominent in cells that make large amounts of proteins to be exported from the cell or inserted into the cell membrane (covered with ribosomes)
10. converts energy stored in food into usable energy for work
11. concluded that all plant are made of cells
14. Membrane, selectively permeable boundary between the cell and the external environment
16. examples are animals, plants, fungi, and protists
17. play a major role in cell division (mitosis)
18. storage center of cell's DNA
19. Wall, boundary around the plant cell outside of the cell membrane that provides structure and support
21. location of protein synthesis
