Transpiration is the process of evaporation of water from the upper surface of the leaves.
(A)Low transpiration indicates the low level of water evaporated and the water potential is negative.
(B)Excessive absorption indicates the entering of the molecule to bulk phase and the water potential is negative.
(C)Excessive transpiration indicates the high level of water evaporated and the water potential is negative.
(D)Guttation occurs due to root pressure. It is the loss of water through leaves in the absence of photosynthesis. Due to root pressure water moves upwards and at this point, the amount of water is more in leaves than the atmosphere so water potential is positive.
So, the correct answer is 'Guttation'.
(A)Low transpiration indicates the low level of water evaporated and the water potential is negative.
(B)Excessive absorption indicates the entering of the molecule to bulk phase and the water potential is negative.
(C)Excessive transpiration indicates the high level of water evaporated and the water potential is negative.

Water Potential in Leaf Tissue During Guttation
During guttation, water potential in leaf tissue is positive, or near zero. This occurs due to the accumulation of water in the leaf tissue, which causes the water potential to become less negative.
Explanation
Guttation is the process by which excess water is exuded from the leaf tips or margins of some plants. It occurs when the rate of water absorption by roots exceeds the rate of transpiration through leaves. This typically occurs at night when the stomata are closed, and the humidity is high.
During guttation, water is forced out of the leaf cells and into the spaces between cells due to the build-up of root pressure. This pressure forces water through the plant's xylem and into the leaf cells, causing the water potential to become less negative. As a result, the water potential in the leaf tissue becomes positive or near zero.
Significance
The positive water potential in leaf tissue during guttation helps to prevent wilting and dehydration of the plant. It also allows for the accumulation of nutrients and other solutes in the leaf tissue, which can be beneficial for plant growth and development.
Conclusion
Water potential in leaf tissue is positive or near zero during guttation due to the accumulation of water in the leaf cells. This process helps to prevent wilting and dehydration of the plant and allows for the accumulation of nutrients in the leaf tissue.
