on tomspination through
leaves and emponction of water from leaves.
Answers
Answer:
The water eventually is released to the atmosphere as vapor via the plant's stomata — tiny, closeable, pore-like structures on the surfaces of leaves. Overall, this uptake of water at the roots, transport of water through plant tissues, and release of vapor by leaves is known as transpiration.
Answer:
Explanation:
Evaporation accounts for the movement of water to the air from sources such as the soil, canopy interception, and waterbodies. Transpiration accounts for the movement of water within a plant and the subsequent loss of water as vapour through stomata in its leaves.In actively growing plants, water is continuously evaporating
from the surface of leaf cells exposed to air. This water is replaced by additional
absorption of water from the soil. Liquid water extends through the plant from the soil
water to the leaf cell surfaces where it is converted from a liquid into a gas through the
process of evaporation. The cohesive properties of water (hydrogen bonding between
adjacent water molecules) allow the column of water to be ‘pulled’ up through the plant
as water molecules are evaporating at the leaf surface. This process has been termed the
Cohesion Theory of Sap Ascent in plants.
