To determine: The plant’s roots that removed the most selenium.
Introduction: Soil is a thin layer of Earth’s crust and consists of inorganic minerals, gases, liquids, and organic matter. They are in large numbers where different types of organisms colonize in the soil. Almost all the essential nutrients, water, and minerals for the growth of plant are directly obtained from the soil.
To determine: What should be done to the plants after they have absorbed selenium.

- 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_forwardDescribe how water molecules move into the plant from the soil. Give an example that includes the concept of water potential.arrow_forwardPlease explainarrow_forward
- (a) Younger plant parts/materials decompose faster compared to older more lignified plant parts/materials; (b) Materials with narrow C:N ratio will decompose more easily compared to materials with wider C:N ratio. A. If statement A is true B. if statement B is true C. both statement A and B are true D. statement A nor B are truearrow_forwardBy which thing the difference in concentration of ions between roots and soil is eliminated?arrow_forwardWhich of the following statements is CORRECT?Aquaporins:a. play an active role in the regulation of water movement in the xylem during mild droughtb. are proteins embedded in the cell walls that transport waterc. play an active role in the regulation of water movement outside the xylem during mild droughtd. are proteins embedded in the mesophyll and bundle sheath apoplast that transport waterarrow_forward
- What is the conclusion of the Experiment on Absoprtion of Water by Roots? A. Cup 1 - with half water and the lid is tightly close to ensure the evaporation of water. B. Cup 2 - with half water and few drops of oil while the plant sample's roots are immersed. C. Cup 3 - with half water and drops of ink while another plant sample's roots are immersed. D. Cup 4 - with plant sample but the roots do not reach the water.arrow_forwardIn which layer would plants find the most nutrients? SOILLAYERS OL A: Humus & Top soil B: Subsoil( Clay) C: Parent Rock Humus Top soil Subsoil D: Bedrock Parent rock Bedrockarrow_forwardChoose all the correct statements for the graph above: A.in a mutant plant that makes TWICE the normal number of stomata on the leaf, we would expect the line to shift down (i.e. water potential would become more negative). B. During the period starting with time B and ending with time D, the water potential in the leaf is increasing. C.Transpiration rates are the highest around time B. D.At time A we expect to see the greatest volume of water moving up the xylem to this leaf.arrow_forward
- The loss of water from a plant by transpiration cools the leaf. Movement of water in transpiration requires both adhesion to the conducting walls and wood fibers of the plant and cohesion of the molecules to each other. A scientist wanted to increase the rate of transpiration of a crop species to extend its range into warmer climates. The scientist substituted a nonpolar solution with an atomic mass similar to that of water for hydrating the plants. What do you expect the scientist's data will indicate from this experiment? The rate of transpiration will be the same for both water and the nonpolar substance. Transpiration rates will fall to zero as nonpolar compounds do not have the properties necessary for adhesion and cohesion. Transpiration rates will increase as nonpolar compounds undergo adhesion and cohesion with wood fibers more readily than water. The rate of transpiration will be slightly lower with the nonpolar substance as the plant will not have evolved with the nonpolar…arrow_forwardPhytoremediation is the utilization of plants in the clean up of a polluted area. In a maximum of four sentences, using a flow chart for illustration, outline the process of phytoremediation. Please include a picture of the flow chart.arrow_forwardExplain how the movement of water molecules from inside the roots to the air space around the mesophyll cells in the leaves is an example of an emergent property.arrow_forward
