Question 5

highly folded membrane system in eukaryotic cells that is the site for protein and lipid synthesis

Answer 5

Question 9

organelle that plays a role in cell division and is made of microtubules

Answer 9

centrioles

Question 10

double-membrane organelle that captures light energy and converts it to chemical energy through photosynthesis

Answer 10

chloroplast

Question 11

in plants, the rigid barrier that surrounds the outside of the plasma membrane, is made of cellulose, and provides support and protection to the cell

Answer 11

cell wall

Question 12

long, tail-like projection with whiplike or propeller motion that helps a cell move

Answer 12

flagella

Question 13

short, hairlike projection that functions in cell movement

Answer 13

cilia

Question 14

net movement of particles from an area of higher concentration to an area of lower concentration

Answer 14

diffusion

Question 15

condition of continuous, random movement of particle but no overall change in concentration of materials

Answer 15

dynamic equilibrium

Question 16

passive transport of ions and small molecules across the plasma membrane by transport proteins

Answer 16

facilitated diffusion

Question 17

diffusion of water across a selectively permeable membrane

Answer 17

osmosis

Question 18

a solutions with the same concentration f water and solutes as inside a cell, resulting in the cell retaining its normal shape because there is no net movement of water

Answer 18

isotonic solution

Question 19

a solution that has a lower concentration of solute outside than inside the cell, causing water to flow into the cell by osmosis

Answer 19

hypotonic solution

Question 20

a solution that has higher concentration of solute outside than inside a cell, causing water to leave the cell by osmosis

Answer 20

hypertonic solution

Question 21

energy-requiring process by which substances move across the plasma membrane against a concentration gradient

Answer 21

active transport

Question 22

energy-requiring process by which large substances form the outside environment can enter a cell

Answer 22

endocytosis

Question 23

energy-required process by which a cell expels wastes and secretes substances at the plasma membrane

Answer 23

exocytosis
