Cells And Cell Processes

Question 0

Osmosis

Answer 0

Diffusion of water across semipermeable membrane

Question 1

Hydrolysis

Answer 1

Breaking apart of peptide bond

Question 2

Hypertonic

Answer 2

Concentration of solute is greater outside cell (water diffuses out)

Question 3

Hypotonic

Answer 3

Concentration of solute greater inside cell (water diffuses in)
Plants prefer; called turgid. Allows for turgor pressure

Question 4

Isotonic

Answer 4

Equal concentration of solute in and out of cell

Animals prefer this

Question 5

Prokaryotes

Answer 5

No membrane bound organelles
No nucleus
Kingdoms Archaea and Eubacteria
Very small

Question 6

Eukaryotes

Answer 6

Opposite of prokaryotes
Kingdoms Fungi, Plants, Animals, Protists
Much larger

Question 7

Vacuole

Answer 7

Plants-used as aid in water distance

Animal- food storage

Question 8

Lysosomes

Answer 8

Breaks down material in cell

Question 9

Rough ER

Answer 9

Contains ribosomes to produce protein

Question 10

Golgi apparatus

Answer 10

Packages materials for secretion

Question 11

Plasma membrane

Answer 11

Double layer of phospholipids with embedded proteins

Bends at double bond site

Question 12

Channel proteins

Answer 12

Provide passage for diffusion of charged particles (facilitated diffusion)

Question 13

Aquaporins

Answer 13

Special channel for water

Question 14

Gated channels

Answer 14

Open and close due to changes in voltage on membrane

Question 15

Carrier proteins

Answer 15

Transports materials against concentration gradient (active transport)

Question 16

Na/K pump

Answer 16

Pushes out 3 Na plus ions and pulls in 2 K ions

Uses energy from ATP

Question 17

Endocytosis

Answer 17

Intakes particles by using plasma as vesicles

Question 18

Expcytpsis

Answer 18

Release substances when vesicles fuses with membrane

Question 19

Phagocytosis

Answer 19

Solid particles

Question 20

Pinocytosis

Answer 20

Liquid particles
