Question 1

What happens during diffusion?

Answer 1

PARTICLES GO FROM HIGHER PLACES OF CONCENTRATION TO LOWRR ONES

Question 2

What can pass through a cell membrane?

Answer 2

Small molecules, small nonpolar and polar molecules, and small lipid solubles

Question 3

What is osmosis and what does it involve?

Answer 3

Osmosis is when particles go through a semipermeable membrane but some specific particles are unable to go through the membrane. Osmosis involves diffusion.

Question 4

What is the cell membrane made up of?

Answer 4

Protein, lipids and carbohydrates.

Question 5

What happens to a cell if there is a higher concentration of water outside of the cell?

Answer 5

water moves into the cell by osmosis faster than it moves out of the cell. If to much water enters it may implode.

Question 6

What happens if there is a higher concentration of water inside the cell?

Answer 6

if there is a higher concentration of water inside the cell than outside the cell (lower concentration of solutes inside), water moves out of the cell by osmosis faster than it moves into the cell. The cell shrinks in size. If too much water leaves the cell, it may die.

Question 7

Know what a cell looks like (diagram) in Liguid solution and what happens if Solute partices cannot move through the cell membrane

Answer 7

If solute particles can’t pass through the cell membrane then it just doesn’t pass. That or that one diagram of the beaker where the water goes to where all the solutes are.

Question 8

Which particle moves through a cell by diffusion?

Answer 8

Oxygen

Question 9

How are osmosis and Diffusion different and how are they Similer.

Answer 9

Both involve particles moving around except diffusion can move around freely anywhere and osmosis is mostly about what happens in cells and how some particles can pass through a semipermeable membrane but others can’t but then for diffusion the particles just sorta go everywhere.

Question 10

Know how Watering a wilted plant cause its stem and Leaves to become fimer & Straighter (eg. Turgid)

Answer 10

When you water a wilted flower a bunch of water starts rushing into the center vacuole and cytoplasm. This causes pressure to the cell wall and then causes the cell to swell. They become turgid and then press together, causing the plant stem to stay upright. If a plant loses to much water, the opposite happens and it begins to wilt.

Question 11

What is exocytosis

Answer 11

EXPELL THE WASTE OF THE CELL
