Transpiration
A)the tubes that carry water and minerals from the roots of a plant to its leaves
B)openings in the skin of a plant, used for gas exchange
C)the process by which water is given off from plants
D)having to do with the tubes that form the circulatory system of plants
E)a strong, central root
C) the process by which water is given off from plants.
Phloem
A)the tubes within a plant which distribute sugars to all the cells of the plant
B)living more than one year
C)openings in the skin of a plant, used for gas exchange
D)hair-like; having to do with fibers
E)having to do with soft, as opposed to woody, plants
A) the tubes within a plant which distribute sugars to all the cells of the plant.
The correct answer is C) the process by which water is given off from plants.
To arrive at this answer, we can break down the options and analyze them individually:
A) the tubes that carry water and minerals from the roots of a plant to its leaves. This refers to xylem, which transports water and nutrients from the roots to the rest of the plant. It does not specifically relate to transpiration.
B) openings in the skin of a plant, used for gas exchange. These are called stomata, and while they are related to transpiration, they are not equivalent to the process itself.
C) the process by which water is given off from plants. This is the correct definition of transpiration. Plants lose water through small openings called stomata on the leaves, stems, and other plant surfaces. Transpiration helps to transport water and nutrients from the roots to the rest of the plant and also aids in cooling the plant.
D) having to do with the tubes that form the circulatory system of plants. This description more closely matches the xylem and phloem, which constitute the plant's vascular system. While transpiration is part of the overall functioning of the vascular system, it is more accurately defined as the process of water loss.
E) a strong, central root. This is not related to the term transpiration, as it refers to a structural feature of plants and not a physiological process.
Therefore, option C) the process by which water is given off from plants is the correct answer for the definition of transpiration.
