The question seems incomplete. Here is the complete question:

Transpiration in plants requires all of the following except

A) Adhesion of water molecules to cellulose

B) Cohesion between water molecules

C) Evaporation of water molecules

D) Active transport through xylem cells

E) Transport through tracheids

Answer:

A) Adhesion of water molecules to cellulose

Explanation:

Transpiration is the process whereby water is moved through a plant and evaporation occurs from parts such as leaves, stems and flowers. Leaf surfaces are filled with pores called stomata. Transpiration cools plants. They are two factors that can influence the rate of flow of water from the soil to a plant's roots: The hydraulic conductivity of the soil and the magnitude of pressure gradient through the soil. Water is transported into the plant's roots and then, into the xylem. The forces of cohesion and adhesion cause water molecules to take the shape of a column in the xylem. Water is moved from the xylem to the mesophyll cells then it evaporates from their surfaces and leaves the plant through diffusion through the stomata. Xylem tissue has tracheids and vessel elements. The transpiration organ in a plant is the epidermus. The stomata are a part of the epidermal system in plants.

active transport through xylem cells.

Explanation:

Transpiration in plants is the loss of water from the aerial organs in the form of steam, it is a natural consequence of the fundamental anatomical characteristics of plants. The cells of the aqueous parenchyma or mesophyll have a wet surface in contact with the intercellular spaces and these, in turn, communicate with the external environment through the stomata, so that the water from the cells of the evaporating mesophyll passes into the air. through the intercellular spaces, and on the other hand the water lost by the leaf parenchyma is replaced by that which comes from the roots through the conductive vessels of the xylem.

The flow of water in the plant depends on the internal anatomy of the plant and the properties of the water. As the transpiration process of the plant becomes more intense (the flow of water through the xylem is greater) the pressure of the xylem decreases, then the difference between atmospheric pressure and xylem pressure increases, which favors the perspiration process.
