Biology Study Guide CH 7 Cell Structure & Function

1. ____________________ was one of the first people to identify & see cork cells.

2. All plants and animals are made of cells…summarizes the work of ______________ & ____________.

3. List three principles of the cell theory.

4. The cell theory applies to _________________________________.

5. Prokaryotes lack a(n)________________________.

6. Define eukaryote…be sure to also include three things that they contain….

7. _________________ are prokaryotes (what organism?).

8. _________________-stores DNA, controls most of the cell’s processes, & contains information needed to make proteins.

9. The _________________ is important to cells mainly because it contains coded instructions for making proteins.

10. _______________ are organelles/structures found in the cytoplasm.

11. _______________-cell organelle that breaks down food into molecules the cell can use.

12. _______________-cell organelle/structure which makes protein using coded instructions from the nucleus.

13. _______________-organelle that converts the chemical energy stored in food into compounds that are more convenient for the cell to use.

14. _________________&________________ are “energy organelles”…which help to provide a cell with energy.

15. ______________ is an energy organelle you would expect to find in plant cells but not in animal cells.

16. The ___________________helps a cell keep its shape…

17. ____________________& _____________________ are structures that help the cell to carry out cell movement…(cilia & flagella are NOT the answer for this particular question);

18. The _______________________helps the cell maintain shape, helps the cell move & helps organelles within the cell move.

19. The main function of the ________________ ____________________ is to support & protect the cell.

20. Unlike the cell membrane, the cell wall is usually made of tough ________________.

21. The _________________ ______________________ serves as the cell’s boundary from its environment in most cells.

22. The function of the ___________________ ____________________ is to regulate what materials enter & leave the cell.

23. Diffusion is the movement of molecules from an area of_______________ concentration to an area of _________concentration.

24. What do the molecules do on each side of the membrane when the concentration of molecules on each side of the membrane is the same?

25. _______________ transport is a means of particle transport that REQUIRES ENERGY.

26. The DIFFUSION of WATER across a selectively permeable membrane is called _____________.

27. An animal cell that is surrounded by fresh water will_______________because the osmotic pressure causes water to move into the cell.

28. ____________________ ____________________refers to cells having different jobs in an organism.

29. __________________-a group of similar cells that perform a particular function. List an example.

30. What is an organ system?

31. List the levels of organization in a multicellular organism from simplest level to most complex beginning with cells.

32. If a cell contains a nucleus, it must be a(n) __________________.

33. The assembly of ribosomes begins in a small dense structure called the ______________.

34. Ribosomes stud the surface of the _________________________________________.

35. Cilia & flagella are made of protein filaments called ________________________.

36. According to the cell theory, all cells come from existing ________________.

37. In a eukaryote, the material between the cell membrane & the nucleus is called the _______________.

38. During cell division, chromatin condenses to form ________________, which are thread-like structures containing genetic material.

39. Define diffusion.

40. Be able to distinguish an animal cell from a plant cell by looking at an unlabeled diagram.

41. From a diagram…be able to label (you have to be able to recognize/identify structures!) & tell the function of cell structures: nucleus, mitochondrion, ribosome, cell membrane, smooth endoplasmic reticulum, rough endoplasmic reticulum, nucleolus, golgi apparatus, cytoplasm;

34 multiple choice, 5 modified true/false; 3 completion; Using Science Skills….Cell Diagram…
