Ambient temperature is 21°C, winds are calm and humidity is 45%. If each plant is transpiring at the rate you calculated for ambient/normal conditions how many liters of water is lost from the field each hour due to transpiration? Show your calculation below. rate = 014 mi /30 minThrough what structure(s) do plants obtain most of their water? roots stomata interior cells leavesImagine yourself as a water molecule in the soil solution of aforest. In a short essay (100–150 words), explain what pathwaysand what forces would be necessary to carry you to the leaves ofthese trees.
- The ability of plants to grow tall and still transport water from their roots to their shoots is a result of evapotranspiration. Evapotranspiration is possible due to the of water molecules. O Cohesion Specific heat Density O AdhesionWhich of the following processes enables a plant to extract nutrients from the soil? O Nutrient anions (sulfate, phosphate, nitrate, etc) are replaced by Cl on soil particles. Released nutrients become available in the soil water. Anions exchange places with cations during anion exchange, which confuses roots and turns HATS into LATS, after which the endodermis synthesizes a caspian endothelium O Cation exchange facilitates the breaking of covalent bonds between nutrients and soil particles O Protons replace nutrient cations on soil particlesTurgor pressure in a plant is directly related to the amount of water within the chloroplasts of the plant cell. how quickly nutrients can be absorbed from the soil. the amount of water within the central vacuole of the plant cell. the number of vacuoles within a plant cell. how quickly water can be absorbed through the roots.

He weighed a willow shoot andplanted it into soil that he had also weighed. After 5 years of addingnothing but water to the plant, he found that the soil had lost only alittle weight, while the plant had grown from 2 kg to about 76 kg. Hetherefore concluded, incorrectly, that water was the sole source of theadded plant material. What other source did he fail to consider in hisexperiment?Unlike the movement of water in the xylem, phloem sap movement is not defined by gravity. It can move upward and downward in the plant. During very hot weather, when the plant root is converting sugar to store as starch, state the role of root and leaves. Tidak seperti pergerakan air di dalam xilem, pergerakan sap floem tidak ditentukan oleh graviti. la boleh bergerak ke atas dan ke bawah dli dalam tumbuhan.
