Answer 1

The Correct Option is A

Water potential - It is zero for pure water Solute potential - It is always negative Pressure potential - It is usually positive

Answer 2

Ans. Water and minerals are transported through conduction throughout the entire body of the plant. For transferring water and nutrients throughout their bodies, plants use a unique system. They make use of a number of water-related processes, such as translocation, absorption, storage, and utilization. Three modes of transportation are available to plants:

• Water and solute uptake and excretion inside individual cells.
• Short distances are covered by the movement of substances from one cell to another.
• Long distances are traveled by sap using the xylem and phloem.

There are three modes of transportation:

1. Diffusion: The molecules in this system travel from a high-concentration region to a low-concentration region. This procedure does not necessitate the use of any energy.
2. Facilitated diffusion: With the help of a carrier, usually a protein, the mechanism transports molecules from an area of higher concentration to a region of lower concentration. Because this process does not require any energy, it is referred to as a passive process.
3. Active Transport: With the help of membrane proteins, this mechanism transports molecules from a lower to a higher concentration region. Because it requires ATP to function, this system is referred to as active transport.

"The measure of potential energy in water that causes water to flow through plants," is the definition of water potential. In order to transfer water to their leaves, which facilitates photosynthesis, plants use their water potential. Solute potential and pressure potential are the two main parts of water potential.

The solute potential, or osmotic potential, of a plant cell is negative. The pressure potential is positive in the plant cell. The system's water potential increases with increasing water concentration.
