Question 50 is based on the following passage.Insectivorous (insect-eating) plants are amongthe most fascinating members of the plantkingdom. They combine the characteristics of aplant with those of an animal. These plants havehighly specialized leaves that capture and digestinsects. The proteins of the digested insectsupply the plant with nitrogen, which is usuallyunavailable in the poor soils in which theseplants grow.The Venus's-flytrap of North and South Carolinais an example of an insectivorous plant. Theleaves of this plant are hinged along the middleand swing upward and inward. An insect landingon the leaf triggers a sensitive motor mechanismthat closes the leaf blades. The captured insectis then slowly digested by enzymes secreted bycells in the leaves.50. According to the passage, what is theprobable effect of growing insectivorousplants in richer soils?A. Plants grow to a much larger size. ndB. Plants are unable to take larger insects.C. Plants are able to obtain nitrogen from2s sources other than insects.D. Plants bloom in more frequent cycles.E. Plants grow with deeper roots.

Insectivorous plants are the most unique plants in the plant Kingdom because they rely on the…

Plants make their own essential elements to complete their life cycle. We have figured out which elements are essential by using hydroponic culture, which involves growing plants in clay instead of soil. Micronutrients of plants include carbon, oxygen, and hydrogen. Plants only require a small amount of macronutrients which include zinc, copper, and iron. There are 4 mistakes in this paragraph, rewrite it to be correct.
Anna conducted an experiment that aimed to determine the deficiency symptoms of tomato plants placed in a hydroponic solution. Six bottles were prepared, and each bottle, except for the positive control, lacked a certain micronutrient. In the positive control, all nutrients were provided. Unexpectedly, the control setup still showed symptoms of micronutrient deficiency. Students later on found out that the relative humidity in the room was very high and transpiration was affected. 1.Explain the appearance of these symptoms in the positive control set-up in lieu of the importance of transpiration? 2.Theoretically, how will thermoregulation of tomato plants be affected if transpiration will not occur 3. Discuss internal factors that could affect the rate of transpiration of the tomato plant.

The Sonoran desert receives some low volume rains during the winter months of January and December while in the summer months of July and August are characterized by violent monsoon-light thunderstorms. The plants in this climate are adapted to aridity (dryness). Several of these plants are adapted to quickly soak up rainfall for longer-term storage. And, plants are well-spaced and photosynthetic area of leaves are small to limit evaporation. With reference to the geochemical cycles of this ecosystem, what particular is particularly limited for primary producers?

Describe the two metabolic pathways that plants use to assimilate N, whether the source is from symbiotic associations with rhizobial bacteria or from direct uptake of nitrate. Your answer must include the name of the primary enzyme involved in each metabolic pathway.

If false, correct them:(a) Boron deficiency leads to stout axis.(b) Every mineral element that is present in a cell is needed by the cell.(c) Nitrogen as a nutrient element, is highly immobile in the plants.(d) It is very easy to establish the essentiality of micronutrients because theyare required only in trace quantities.

Two groups of tomatoes were grown under laboratoryconditions, one with humus added to the soil and one acontrol without humus. The leaves of the plants grownwithout humus were yellowish (less green) compared withthose of the plants grown in humus-enriched soil. The bestexplanation is that(A) the healthy plants used the food in the decomposing leavesof the humus for energy to make chlorophyll.(B) the humus made the soil more loosely packed, so waterpenetrated more easily to the roots.(C) the humus contained minerals such as magnesium andiron needed for the synthesis of chlorophyll.(D) the heat released by the decomposing leaves of the humuscaused more rapid growth and chlorophyll synthesis.
Some plants actually thrive in soils that most plants find challenging. One example is the California redbud which grows on serpentine soil (a soil type high in toxic magnesium and nickel but low in calcium). Some of these species even need to be grown in the unusual soils to survive. Others can tolerate more standard soil conditions. If you wanted to grow some of these unusual plants in their native soil, what is one risk to you as the gardener? How does tolerance to such (normally toxic) soil help the plant?
