cells

Question 1

plasma membrane

Answer 1

movement in & out of cell

Question 2

microvilli

Answer 2

folds plasma membrane -> increases absorption

Question 3

nucleus

Answer 3

contains DNA molecules, site of ribosome synthesis

Question 4

nucleolus

Answer 4

assembly site for ribosomes, does not control cellular activity

Question 5

chromatin

Answer 5

thin strands of DNA w/ proteins within nucleus

Question 6

cytoplasm

Answer 6

area of cell that includes cytosol and organelles

Question 7

cytosol

Answer 7

fluid portion of cytoplasm

Question 8

mitochondria

Answer 8

ATP, cellular respiration

Question 9

ribosomes

Answer 9

site of protein synthesis

Question 10

rough er

Answer 10

transports proteins, synthesizes phospholipids
site for secretary and membrane protein synthesis

Question 11

smooth er

Answer 11

fatty acid+steroid synthesis; detoxifies toxic substances

Question 12

golgi

Answer 12

receives and modifies proteins from RER, sorts +transports

Question 13

secretory vesicles

Answer 13

secrete substances outside the cell by exocytosis

Question 14

lysosomes

Answer 14

enzymes digest and recycle worn out organelles

Question 15

peroxisomes

Answer 15

detoxify harmful substances

Question 16

cytoskeleton

Answer 16

3 kinds of protein filaments
-shape
-cell movement
-organelle movement

Question 17

centrosomes

Answer 17

form mitotic spindle; needed to form cilia and flagella

Question 18

cilia

Answer 18

abundant, hair-like cell projections, move particles around cell

Question 19

flagella

Answer 19

long cell projection; whip-like motion moves sperm

Question 20

interphase

Answer 20

DNA replicates

Question 21

mitosis

Answer 21

nuclear division

Question 22

prophase

Answer 22

nuclear membrane disappears, chromatin condenses into chromosomes; centrioles move opposite poles, spindle fiber forms

Question 23

metaphase

Answer 23

chromosomes line up, spindle fibers attach to centromeres of chromosomes

Question 24

anaphase

Answer 24

chromatids of chromosomes separate; move opposite poles

Question 25

telophase

Answer 25

cell reverses prophase activities, spindle breaks up, nuclear membrane reappears

Question 26

cytokinesis

Answer 26

cytoplasm division into two genetically identical daughter cells

Question 27

crenation

Answer 27

to shrink or shrivel

Question 28

hemolysis

Answer 28

destruction of red blood cells

Question 29

simple diffusion

Answer 29

high concentration to low concentration
solids, liquids, or gas is moved across plasma membrane

Question 30

tonicity

Answer 30

measure of relative solute concentration between 2 solutions

Question 31

isotonic

Answer 31

same solute

Question 32

hypertonic

Answer 32

more solute

Question 33

hypotonic

Answer 33

less solute

Question 34

osmosis

Answer 34

low concentration to high concentration

Question 35

in a dialysis bag, glucose and iodine are?

Answer 35

solutes

Question 36

passive processes use what kind of energy to move substances across plasma membrane?

Answer 36

kinetic energy

Question 37

red blood cell in hypertonic solution

Answer 37

crenate

Question 38

red blood cell in hypotonic solution

Answer 38

hemolyze
