CH 5 Test Material

Question 1

Define Permeable

Answer 1

Allowing Passage

Question 2

Define Impermeable

Answer 2

Not allowing passage

Question 3

Define Concentration

Answer 3

refers to the amount of a substance (like solute) that is dissolved in a given amount of another substance (like solvent)

Question 4

Define Diffusion

Answer 4

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

Question 5

Define Osmosis

Answer 5

The diffusion of water across a selectively permeable membrane from an area of higher water concentration (or low solute concentration) to an area of lower water concentration (or high solute concentration)

Question 6

Define Endocytosis

Answer 6

The process by which a cell moves large amounts of material, or non-dissolved particles, into its cytoplasm from the outside environment

Question 7

Define Exocytosis

Answer 7

The process by which large amounts of material, or large non-dissolved particles, are moved from a cell’s cytoplasm to the outside environment

Question 8

Define Phagocytosis

Answer 8

A type of endocytosis in which a cell uses pseudopods to move non-dissolved solid particles into its cytoplasm from the outside environment

Question 9

How does the Cell Membrane work?

Answer 9

The cell membrane is a natural gatekeeper around a cell. The cell membrane controls the movement of materials into and out of the cell. The cell membrane is permeable to some materials and impermeable to others. The cell membrane plays an important role in keeping harmful substances out of the cell and in removing wastes.

Question 10

What is Turgor Pressure?

Answer 10

The outward pressure that is exerted on a plant cell wall by the cell contents when water is taken in by Osmosis

Question 11

What is the difference between Exocytosis and Endocytosis?

Answer 11

The process by which non-dissolved materials, or large amounts of material, are brought into the cell from the outside environment is called Endocytosis

The process by which large amounts of material, or large non-dissolved particles, are moved from the cell’s cytoplasm to the outside environment is called Exocytosis

Question 12

Why is endocytosis and exocytosis simillar but opposite?

Answer 12

they are both play a role in bringing large particles to leave and exit the cell

endocytosis- particles enter the cell
exocytosis- particles leave the cell
