Cell Transportation

Question 1

What are the three types of passive transport?

Answer 1

1. Simple diffusion
2. Facilitated diffusion
3. Osmosis

Question 2

What are the two types of active transport?

Answer 2

1. Endocytosis
2. Exocytosis

Question 3

What happens within active transport?

Answer 3

1. Helps molecules that need to move against against their concentration gradient into the cell
2. This requires ATP, a by product of respiration

Question 4

What are the two types of endocytosis?
active transport

Answer 4

1. Phagocytosis
2. Pinocytosis

Question 5

What happens within endocytosis?

Answer 5

1. Large molecules are able to enter the cell; the membrane shape is changed due to ATP

Question 6

What happens within exocytosis?
active transport

Answer 6

1. Exocytosis allows waste materials and cellular products to be removed

Question 7

What happens within phagocytosis?

Answer 7

1. The plasma membrane surrounds a molecule and engulfs it
2. A vacuole is created where enzymes digest the molecule

Question 8

What happens within Pinocytosis?

Answer 8

1. The plasma membrane surrounds droplets or fluid and engulfs it
2. The droplets of fluid are held in a vesicle and contain solutes that the cell needs
