- Plants obtain water and nutrients from the soil.a. What structure in a plant uses water in a metabolic reaction? What is this metabolic process called? b. Describe in detail two mechanisms by which water can move from the roots to this location c. If a plant was exposed to saltwater, how would it affect the above processes? Be specific, including a discussion of water potential d. How do plants absorb minerals from the soil? Does this process require energy?arrow_forwardAs scientists research and develop biofuels, they are faced with many tradeoffs. A plant's usefulness for biofuels depends on how much energy can be collected from the plant matter. In addition, growing plants on a large scale requires energy—such as the gasoline and power needed to run tractors and other harvesting equipment or the energy needed to create and distribute fertilizers and pesticides. An efficient biofuel would maximize the ratio of energy output to energy input. The following graph illustrates the results of a 10-year study analyzing three different crops used in biofuel production. The data show how much energy was required to grow each crop on 1 hectare of land (energy input) and how much energy was recovered from the total crop on each hectare of land (energy output). A hectare is a measurement of an area of land and is roughly the same as 2.5 acres. What was the estimated energy input of the grass? A. kcal x 10^6 B. 2kcal x 10^6 C. 8kcal x 10^6arrow_forwardAs scientists research and develop biofuels, they are faced with many tradeoffs.
