Turgid, Flaccid and Plasmolysed

Q.

A cell will swell up if

1. The concentration of water molecules in the cell is higher than the concentration of water molecules in the surrounding medium

2. The concentration of water molecules in surrounding medium is higher than water molecules concentration in the cell

3. The concentration of water molecules is same in the cell and in the surrounding medium

4. Concentration of water molecules does not matter

Q.

Why cant plasmolysis occur in animal cells?

Q.

Give reason for potato cubes when placed in water become firm and increase in size.

Q. A cell placed in strong salt solution will shrink because

1. cytoplasm will decompose
2. mineral salts will break the cell wall
3. salts enters the cell
4. water comes out by exosmosis

Q. Phytohormones are transported passively and unidirectionally.

1. False
2. True

Q. What would be present in between plasma membrane and cell wall in a plasmolysed cell?

1. Hypertonic solution only
2. Solutes only
3. Hypertonic solution and water lost from cell gap
4. Gases

Q. A cell kept in a hypertonic solution undergoes ________.

1. Plasmolysis
2. Osmosis
3. Transpiration
4. Imbibition

Q.

Name the cell in a fully extended condition.

Q.

What is plasmolysis in a plant cell?

Q. Plasmolysis occurs when a plant cell is placed in:

1. Isotonic solution
2. hypertonic solution
3. hypotonic solution
4. None of these

Q.

List two points of differences between the following.

Isotonic, hypotonic and hypertonic solutions.
