Plant and Human Physiology: Key Concepts and Exam Questions

Water Relations in Plants Water relations in plants are crucial for productivity, absorption, and transport. The most important factor affecting plant productivity is water availability, and various properties of water are due to hydrogen bonding between water molecules. -...

Which factor mainly affects productivity in plants due to its non-availability?

Water

The various properties of water are mainly due to which type of bond between water molecules?

Hydrogen bond

Hydrogen bond

What is Imbibition?

Imbibition is a surface phenomenon where solid particles absorb water, causing them to swell. This process is crucial for initial water absorption during seed germination.

Describe the movement of water in terms of water potential.

Water moves from a region of higher water potential to a region of lower water potential. For example, if cell X has $-1$ Pascal and cell Y has $-4$ Pascal, water will move from cell X to cell Y.
