osmosis(the actually important part)

Question 1

What is osmosis?

Answer 1

Net movement of water from high water potential to low water potential through a semi permeable membrane

Question 2

requirements for osmosis

Answer 2

Partially permeable membrane, water potential difference, water molecules

Question 3

what happens when an animal cell is placed in a isotonic solution?

Answer 3

The animal cell’s shape remains the same as before.

Question 4

what happens when an animal cell is placed in a hypotonic solution?

Answer 4

The animal cell becomes swollen and lysed as water enters the cell.(big joe’s cells)

Question 5

what happens when an animal cell is placed in a hypertonic solution?

Answer 5

The animal cell crenates as water leaves the cell

Question 6

what happens when a plant cell is placed in a isotonic solution?

Answer 6

The plant cell is flaccid as water is neither entering the cell nor exiting(0 net movement)

Question 7

what happens when an plant cell is placed in a hypotonic solution?

Answer 7

The plant cell is turgid as water is entering the cell(the cell cannot lyse as it has a cell wall and is in the optimum state)

Question 8

what happens when an plant cell is placed in a hypertonic solution?

Answer 8

The plant cell becomes plasmolysed as water leaves the cell

Question 9

why is the hypotonic state ideal for plants?

Answer 9

The vacuole exerts a lot of turgal pressure onto the cell wall and pushes it outwards when in the hypotonic state. This allows plants to stay upright as they have no skeleton.
