Solution

The correct option is B B and C
There are 8 types of aquaporins present in the cell membrane
Water potential is given by the total sum of pressure potential and solute potential.
Guttation is the process of release of water droplets from pores on plant surface due to high root pressure and humidity. This occurs to remove excess water.
Minerals enter root by active absorption.
So the correct answer is ' B and C'.

Q. If you ignore the factors which are negligible and universal, which are the main components that determine water potential?

Absorption of minerals by the epidermal cells of root and root hair causes the water to enter from surrounding soil into roots. It further reaches the root xylem. Thus, due to a continuous uptake of water by root cells, a water pressure is created in the root xylem. This pressure is called as________
