Circle the Correct Answer
7. The cell wall of plant cells is made is made up of (cellulose / phospholipids).
8. Cell membranes are made up of (cellulose / phospholipids).
9. The (cell wall / cell membrane) regulates what enters and exits the cell.
10. The (mitochondria / lysosomes) release energy from glucose.
11. Without ribosomes, a cell would not be able to produce (proteins / carbohydrates).
12. Cells that have great energy needs will contain many (lysosomes / mitochondria).

1.
DIFFUSION
Moves small polar and nonpolar molecules in and out of cells along a concentration gradient.
2.
DIFFUSION
Moving molecules from an area of high to lower concentration
3.
FACILITATED DIFFUSION
Glucose moves into a cell from an area of high to lower concentration via membrane spanning
proteins.
4.
OSMOSIS
Moving water from an area of high to lower concentration
5.
DIFFUSION
Oxygen moves from the blood stream into body cells along a concentration gradient.
6.
ENDOCYTOSIS
Taking large particles into a cell
7.
EXOCYTOSIS
Moving large particles out of a cell

10. What is the hypothesis for this experiment? I hypothesize that cell size will change in solutions with different
solute concentrations.
11. What is the independent variable for this experiment? CONCENTRATION OF SOLUTE IN SOLUTION
