1. B; the
Cells A and B are the same size, shape and temperature, but cell A is
diffusion
metabolically less active than cell B, and cell B is actively converting
gradient in
oxygen to water in cellular respiration. Oxygen will diffuse more
cell B is
rapidly into Cell because .
steeper
2. endocytosis procedure that cells use to import large molecules across their plasma
membrane
3. active transport Used to move small molecules against a concentration gradient.
4. passive transport involves small molecules that require no special assistance in
crossing the mem- brane.
5. exocytosis used to move products outside of the cell
6. osmosis type of passive transport that involves the movement of water across a
membrane
7. 30 If a cell contains 60 chromatids at the start of mitosis, how many
chromosomes will be found in each daughter cell at the completion of
the cell cycle?
8. anaphase stage of mitosis in which the chromatids of each chromosome have
separated,
and the daughter chromosomes are moving to the poles of the cell.
9. prophase stage of mitosis in which the chromatin condenses into discrete
chromosomes
visible with a light microscope, the mitotic spindle begins to form, and the
nucleolus disappears but the nucleus remains intact.
10. prometaphase stage of mitosis in which the nuclear envelope fragments and the
spindle micro- tubules attach to the kinetochores of the chromosomes.

11. metaphase stage of mitosis in which the spindle is complete, and the chromosomes
attached to microtubules at their kinetochores are all aligned at the
metaphase plate.
12. telophase stage of mitosis in which daughter nuclei are forming and cytokinesis has
typically begun.
13. What are the 4 phases of the cell cycle?

M phase, Inter-
phase, G1
phase, S phase,
and G2 phase
14. M phase (mitotic) phase of the cell cycle that includes mitosis and cytokinesis
15. inteprhase phase of cell cycle when the cell isn't dividing; cellular activity is high,
chromo-
somes and organelles duplicate and cell size increases; cell spends most of its
time in this phase
16. G1 Phase the growth phase of the cell cycle; consists of portion of interphase before
DNA
synthesis begins.
17. S phase synthesis phase of the cell cycle; portion of interphase during which DNA is
replicated.
18. G2 phase second growth phase of the cell cycle consisting of the portion of interphase
after DNA Synthesis occurs
19. CO2 is released What also occurs when pyruvate is converted to acetyl CoA before the citric
acid
and NADH is syn- cycle?

21. photosynthesis process by which plants use sunlight, water, and carbon dioxide to create
oxygen and energy in the form of sugar.
