Osmosis

Question 1

What is the definition of osmosis?

Answer 1

This is the movement of water from an area of high water potential to and area of low water potential through a semi - permeable membrane.

Question 2

What is the equation for water potential?

Answer 2

Water potential of cell = solute potential + pressure potential

Question 3

What is turgidity?

Answer 3

Turgidity is a cellular state in which plants cells have absorbed water. Plant cells rely on turgor for support, it strength limits the expansion of cell membrane as water moves in by osmosis, the opposing forces of the cell membrane and cell wall create turgor to support each other.

Question 4

What is it called when the cell membrane is close to losing contact with the cell wall?

Answer 4

This is known as incipient plasmolysis

Question 5

What is it called when a plant loses to much water?

Answer 5

Plasmolysis

Question 6

…

Answer 6

Turgidity is a cellular state in which plants have absorbed water. Plant cells rely on turgor for support, it strength limits the expansion of the cell membrane as water moves in by osmosis, the opposing forces of the cell wall and cell membrane create turgor to support each other.

Question 7

….

Answer 7

Turgidity is a cellular state in which plants have absorbed water. Plant cell rely on turgor for support, it strength limits the expansion of the cell membrane as water moves in by osmosis, the opposing forces of the cell wall and cell membrane create turgor to support each other.

Plasmolysis is the state just before the cell wall and cell membrane are about to split due to losing to much water.

Question 8

Where are spindle fibres formed?

Answer 8

In G2 phase

Question 9

What is turgidity?

Answer 9

A cellular state where plants absorb water

Question 10

What does turgidity do?

Answer 10

It strength limits the expansion of a plant cell wall as water moves in by osmosis, it supports cell wall.
Opposing forces of cell wall and cell membrane create turgor to support each other.
