Cellular Trasport

Question 1

Diffusion -

Answer 1

particles tend to move from an area where they are
more concentrated to an area less concentrated.

Question 2

passive transport

Answer 2

In cells, substances can diffuse across membranes WITHOUT
requiring the use of energy.

Question 3

Osmosis

Answer 3

diffusion of water across a selectively permeable
membrane

Question 3

*Osmosis affects cells depending on the type of solution they are
placed in:

Answer 3

Isotonic, hypertonic or hypotonic.

Question 4

homeostasis

Answer 4

enables cell membrane to regulate cells internal
environment

Question 5

Facilitated diffusion -

Answer 5

molecules that cannot diffuse on their own,
moves through protein channels in membrane.

Question 6

Active transport -

Answer 6

transport protein (carrier) protein requires
ENERGY to help move particles across the membrane against a
force (concentration gradient)

Question 7

Endocytosis VS Exocytosis

Answer 7

Endocytosis: large particles are engulfed, then enclosed by cell membrane - moves into cell.

Exocytosis: large particles are released from cell by secreting them or expelling them out.
