- Name four plant structures that move water from soil to the air above the forest canopy (through a tree). For each named structure, describe how it works to move water into/within/out of the plant. In your answer, focus on how these structures allow a tree to move water high into the air without a mechanical pump; illustrate how this is possible with your answer.arrow_forwardMany woody plant species are capable of growing to incredible heights, despite the need to transport water throughout the length of the plant. The ability of these tall plants to transport water to their tops is a direct result of of water molecules. Group of answer choices Cohesion Water's High Specific Heat Adhesion Evapotranspirationarrow_forwardDescribe the pathway water would follow from the soil to the stem of a plant. Describe the water's movement through the cells, tissues, and systems of the plant body.arrow_forward
- Cation Exchange capacity is: Group of answer choices a. The amount of cations that can be held by a given mass of soil. b. Affected by soil texture c. Affected by the amount of organic matter/Humus in a soil. d. Affected by the amount of clay in a given soil e) All of the abovearrow_forwardIn plants, water is transported through vessels called xylem. The cohesiveness of water molecules allows them to travel up the walls of the vessel. However, for most plants this is not enough to move the water all the way to the top of the plant. How do plants overcome the force of gravity and move water to their upper tissues?arrow_forwardDescribe how water molecules move into the plant from the soil. Give an example that includes the concept of water potential.arrow_forward
- Choose the statements that apply to transpiration in the cohesion-tension theory. (Check all that apply) Check All That Apply The H-bonds in water allow for cohesion. Water pressure builds in roots to drive water up the plant. Exposed water in leaves evaporates into drier air. Water forms a continuous stream from leaf into the root. In addition to water, heat is lost cooling the plant during transpiration.arrow_forwardAn important factor for plants is the amount of water lost for each molecule of carbon dioxide absorbed. How could the plant be harmed if it loses a lot of water for each carbon dioxide molecule, that is, if the ratio is high? Would this be more important for a plant in a rainy habitat or one in a desert?arrow_forwardExamine the sketch of the xylem elements below (they are displayed horizontally to save page space), these elements are from top to bottom A, B, C, and D.

- Describe the pathway water would take up the stem to the leaf of a plant. Describe the water's movement through any cells, tissues, and/or systems of the plant body.arrow_forwardSelect all that are true regarding soil a. the most abundant element of soil is inorganic mater b. plants passively acquire cations by using ATP to pump H+ into the soil c. soil plays key roles in water regulation and buffering of pollutants d. soil is an essential source of carbon for plants e. plants use H+ from photosynthesis to acquire cations f. anions are unbound in the soil and freely travel into plant roots with water g. cation exchange is required because cations are bound to negatively charged soil particles h. H+ works well for the cation exchange because it is a small molecule with a strong charge 2. Select all that apply to plant nutrition a. green manure can restore minerals to soil but is to expensive for farmers to use b. mineral deficiencies cause symptoms like chlorosis, a browning and death of plant tissue c. fertilizers typically contain nitrogen, potassium, and phosphorus,…arrow_forwardExplain the difference between the adhesion and cohesion properties of water molecules, and discuss how the adhesion-cohesion mechanism affects the process of water transport in plants.
