If a plants xylem were destroyed it would hinder its ability to ____
A
Absorb water from soil
B
Absorb water from leaves
C
Absorb sunlight
D
Conduct water to the leaves
Explanation: 

Detailed explanation-1: -Xylem is the vascular vessel which transports water from the roots to the leaves where it is used for the process of photosynthesis. In the absence of xylem, water will not reach the leaves and thus, photosynthesis won’t take place for it needs 6 H2O.As a result the plant wilts and dies.

Detailed explanation-2: -Xylem is one of the two types of transport tissue in vascular plants, phloem being the other. The main function of xylem is conduction of water from roots to the leaves via the stem.

Detailed explanation-3: -Xylem is a vascular tissue. It is used for the conduction of water. Xylem is also termed as conducting tissue. Xylem helps get water from the roots to the plant body, such as leaves and stems.

Detailed explanation-4: -Water is lost from the leaves via transpiration (approaching p = 0 MPa at the wilting point) and restored by uptake via the roots. When (a) total water potential () is lower outside the cells than inside, water moves out of the cells and the plant wilts.
