Question
Chapter 26, Problem 1CT
Summary Introduction
To explain:
The importance of nitrogen for the plants.
Introduction:
Plants are autotrophic organisms that are present on the Earth. Plants take nutrients from the soil and the environment. They require carbon dioxide and water in the presence of sunlight to make glucose. The deficiency of nutrients leads to retardation in the growth of the plant.

Nitrogen deficiency stunts plant growth and causesleaves to turn yellow and then die. Why does nitrogendeficiency cause these symptoms? Hint: Think aboutwhich biological molecules incorporate nitrogen atoms.
To determine: The causes of nitrogen deficiency in
plants.
Describe the journey of a carbon atom. Begin with it as atmospheric CO2 and end with it as part of a cell wall molecule in a root. Describe a) the structures through which the C atom moves, b) the reason it moves, and c) any cellular process with which it is involved

Why do plants seldom exhibit deficiency symptoms of carbon, hydrogen and oxygen although they are used by the plant in large quantities? And lastly, what is the role of pH in nutrient availability?arrow_forwardMatch the -troph term with the correct definition. Each term applies to only 1 definition.

- 33) True or False: Plants undergo photosynthesis to make glucose using light energy. Plants also use cellular respiration to break down glucose and convert it into energy (stored as ATP). A) True B) Falsearrow_forwardThree plants grow side by side in a pond. Glucose and starch are measured for each and shown in relative units below, along with the pH of the vacuole at dawn and at noon. Plant Glucose Starch Vacuolar pH, dawn Vacuolar pH, noon A 100 50 1 4 B 100 10 4 4 C 1,000 2 4 4 Part A:Explain what kind of photosynthesis is being done by each plant with some details about how each works. Justify your answer. Part B:Decipher which plant is biochemically defective after the light-independent reactions and explain how you deciphered this.arrow_forwardPlants 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.arrow_forward
- Which definition is INCORRECT? A) O Photoexcitation: light absorption leads to raising an electron to a higher energy state. C) O Photolysis: light absorption coupled to splitting a molecule. D) O Photophosphorylation: a form of substrate level phosphorylation used for ATP formation E) O Photosynthesis: is often photoexcitation and photolysis coupled with CO2 fixation and biosynthesisarrow_forwardThe green color of plants is explained by the wavelengths of light that are reflected, transmitted, and absorbed by the chlorophylls in the thylakoids. Which of the following statements is true? Plants appear green because chlorophylls reflect and transmit yellow and green wavelengths of light, and absorb red and violet-blue wavelengths of light. Plants appear green because chlorophylls reflect and transmit red and blue wavelengths of light, and absorb yellow and green wavelengths of light. Plants appear green because chlorophylls reflect and transmit red and blue wavelengths of light, and absorb white wavelength of light. Plants appear green because chlorophylls reflect and transmit white wavelength of light, and absorb red and violet-blue wavelengths of light.arrow_forwardChlorophyll is the green pigment found in plants. Which of the following statements can be implied regarding chlorophyll? O Chlorophyll does not absorb in the UV region. O Chlorophyll is made up of only C- H, C- C, C- N and C-O single bonds. O Chlorophyll uses the blue and red colors for photosynthesis. O Chlorophyll uses the green color for photosynthesis.arrow_forward
