Sample Questions

1multiple correct

Which of the following are essential elements required for plant growth?

Show answer

Nitrogen (N), Phosphorus (P), Potassium (K)

NPK (Nitrogen, Phosphorus, and Potassium) are the three most important essential elements for normal growth and development of plants. Sodium is not an essential element.

2true false

Imbibition is the process of adsorption of water molecules by dry hydrophilic colloids.

Show answer

True

Imbibition is indeed the process of adsorption of water molecules by dry hydrophilic colloids due to surface attraction. Examples include swelling of seeds and wooden doors.

3multiple choice

What happens when a cell is placed in a hypertonic solution?

Show answer

Cell becomes flaccid

In a hypertonic solution (higher solute concentration), water leaves the cell by exosmosis, making it flaccid and shrunken.

4multiple correct

Which of the following are functions of water in plants?

Show answer

Serves as a solvent, Raw material for photosynthesis, Helps in transpiration, Facilitates gas exchange

Water serves multiple functions: solvent for substances, raw material for photosynthesis, helps in transpiration, and facilitates gas exchange by dissolving gases. Structural support is provided by turgidity, not water directly.
