break down of very long chain fatty acids through oxidation

Question 18

chroloplasts

Answer 18

found in plants that allow them to make their own food

Question 19

mitochondria

Answer 19

power house of cell

Question 20

cytoskeleton

Answer 22

animal

Question 23

large central vacuole

Answer 23

plant

Question 24

substance enter cells either

Answer 24

passively or actively

Question 25

passive transport

Answer 25

doesn’t require energy

Question 26

active transport

Answer 26

use ATP or energy

Question 27

diffusion

Answer 27

movement of material from high concentration to an are of low concentration

Question 28

osmosis

Answer 28

diffusion of water across a selectively permeable membrane

Question 29

hypotonic solution in animal

Answer 29

lysed (high concentration of of solute in the cell

Question 30

hypotonic in plant

Answer 30

turgid or normal (high solute concentration in the cell

Question 31

isotonic animal

Answer 31

normal (equal concentration

Question 32

isotonic in plant

Answer 32

flaccid (equal concentration

Question 33

hypertonic in animal

Answer 33

shriveled (more concentration of solute outside the cell

Question 34

hypertonic in plant

Answer 34

plasmolyzed (more solute concentration out of the cell

Question 35

facilitated transport (diffusion)

Answer 35

allows diffusion of large membrane insoluble compounds like sugar
particles move from high to low concentration

Question 36

facilitated transport

Answer 36

substance pass through channel proteins like water through aquaporins

Question 37

Active transport

Answer 37

requires specific membrane transport proteins ( sodium potassium pump

Answer 39

into cell membrane pass through plasma membrane

Question 40

exocytosis

Answer 40

out of the cell through plasma membrane

phagocytosis

Answer 41

involves engulfing of large particles by the cell

Question 42

pinocytosis

Answer 42

involves the engulfing of liquids or very small particles
