Imbibition

Q.

Give an illustration of imbibition.

Q.

Turgor pressure is always equal and opposite to

1. Osmotic pressure.

2. Wall pressure.

3. Osmotic potential.

4. Water potential.

Q.

Arrange the following plant materials in order of their imbibing capacity from high to low.

1. Proteins, starch, cellulose

2. Starch, proteins, cellulose

3. Cellulose, proteins, starch

4. Cellulose, starch, proteins

Q.

Why seeds kept in water swell up?

1. Diffusion pressure deficit of seed is very high.

2. OP of water is high.

3. Water potential gradient develops between the seed coat and water.

4. OP inside the seed is low.
