sides of the cell membrane ____________ is reached.
24. Cells shrivel when they are in this type of solution.
25. Cells might swell and rupture when in this type of solution.
26. “Same strength” means this type of solution.

Answers to study guide:
1. the 1st person to identify & see cells ( he was looking at cork
cells)
2. all plants are made of cells
3. he was a Dutch lens maker and saw tiny organisms in pond
water
4. Said all animals are made of cells
5. Said that cells come from existing cells
6. a nucleus
7. a nucleus and membrane-bound organelles
8. all living things are composed of cells, cells are the basic units
of structure & function, new cells come from existing cells
9. nucleus
10.genetic material
11. attaches carbohydrates to proteins & moves them to their
final destination
12.helps a cell to keep its shape/involved in cell movement
microfilaments and microtubules
13.support & protect the cell
14.break down food particles (lipids, carbs, protiens) into
particles that could be used by the cell and can break down
other organelles that have outlived their usefulness
15.ribosomes
16.chloroplasts & cell walls
17.regulates materials that enter and leave the cell
18.protein
19.movement of particles from high to low concentration
20. active transport
21.osmosis
22. hypotonic
23. equillibrium
24. hypertonic
25. hypotonic
26. isotonic
27. hypertonic
28. endocytosis – cells take in substances [phagocytosis is when
cells take in large clumps]
exocytosis – cells move substances out
29. facilitated diffusion, osmosis, diffusion
30. active transport moves substances against the
concentration gradient (low concentration to high) and requires
energy from the cell
[facilitated diffusion is still diffusion in that the molecules are
moving from high to low concentration and is passive]
31.Phagocytosis is the movement of food into the cell and
pinocytosis is the movement of water.
32. true
