Question 1

What is diffusion?

Answer 1

The process by which molecules or cells pass through a membrane that each have a different amount of a solute

Question 2

Define passive diffusion

Answer 2

Diffusion that happens, hence the name, passively, cells are able to pass through the membrane without any help and it takes no energy for it to happen. High to low concentration

Question 3

Define facilitated diffusion

Answer 3

Diffusion that requires a protein to be at the membrane to allow select cells or molecules to pass into the other side. High to low concentration, requires no energy to happen

Question 4

Define osmosis

Answer 4

Process of diffusion of water across a semi-permeable membrane

Question 5

Define hypertonic

Answer 5

Having the higher, or a lot of an amount of a solute

Question 6

Define hypitonic

Answer 6

Having the lower, or less amount of a solute

Question 7

Define isotonic

Answer 7

Both sides having equal amounts of solute in them

Question 8

Define active transport

Answer 8

A process of diffusion in which cells or molecules are going through a “protein pump” that contrarily takes them from a place with low concentration to high. This one requires energy to happen.

Question 9

Define endocytosis

Answer 9

The use of vacuoles as vehicles to bring IN a substance into a cell

Question 10

Define exocytosis

Answer 10

The use of vacuoles as vehicles to bring OUT a substance from a cell

Question 11

What is the importance of surface area to volume ratio?

Answer 11

It is important so that there is an even and quick process of exchange of resources and waste in the cell so that it may live

Question 12

Which way does a solute diffuse across a membrane

Answer 12

From higher concentration to lower until both sides are isotonic

Question 13

Which way will water diffuse across a membrane in osmosis
