Introduction:
Many factors are required for the proper plant growth and maintenance. Nutrients that are essential to plants for their growth are called as essential nutrients. Essential nutrients are classified as macronutrients and micronutrients. Macronutrients are the nutrients that are required in higher amounts (carbon, nitrogen, oxygen, phosphorous, sulfur, potassium, hydrogen, and calcium). The micronutrients are the nutrients that are required in lesser amount (zinc, copper, boron, chlorine, manganese, iron, and molybdenum). These nutrients cannot be obtained through different sources such as water, soil, air, and through fertilizers (applied in the field) in different forms.

Statement 1 is wrong, Statement 2 is correct d. Statements 1 and 2 are both wrongarrow_forwardAn increase in temperature will _______ transpiration. An increase in humidity will ______ transpiration. Select one: a. increase, increase b. increase, decrease c. decrease, increase d. decrease, decreasearrow_forwardCation 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_forward
- Select 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_forwardPatchouli essential oil comes from the patchouli plants of tropical East and Southeast Asia; it is: Choose one answer. a. steam distilled from the leaves b. extracted via enfleurage c. steam distilled from the flowers d. macerated from the leavesarrow_forwardWhich one of the following does not affect the rate of transpiration ?

- Soil pH affects availability of nutrients for root absorption. The following statements are true except* a. Low pH results in an increase in Aluminum toxicity. b. Low pH results to unavailability of major nutrient elements. c. Toxic metals are more available in acidic soil. d. Low pH results in slow activity of soil-inhabiting microorganisms.arrow_forwardUse of synthetic fertilizers often leads to the contamination of groundwater with nitrates. Nitrate pollution is also a suspected cause of anoxic "dead zones" in the ocean. Which of the following processes is most likely to help reduce nitrate pollution?
