Carbon, hydrogen, and oxygen are _______ for plants.
- a. macronutrients d
- b. micronutrients e
- c. trace elements
- d. required elements
- e. both a and b
- f. both a and d
Introduction: Many factors are required for the proper plant growth and maintenance. The nutrients that are essential for the plants for their growth are known as essential nutrients. The essential nutrients are classified as macronutrients and micronutrients. The micronutrients cannot be obtained through different sources such as water, soil, air, and through fertilizers (applied in the field) in different forms.
Answer to Problem 1SQ
Correct answer: Carbon, hydrogen, and oxygen are macronutrients and required elements for the plants.
Hence, the correct answer is option f.
Explanation of Solution
Reason for the correct answer:
The macronutrients are the nutrients that are required in higher amounts. They include carbon, nitrogen, oxygen, phosphorous, sulfur, potassium, hydrogen, and calcium. These nutrients are also the essential elements for the plants. Water contains hydrogen in the form of H2O and plant can uptake water from the soil through its roots. Oxygen is abundant in the atmosphere. Usually, the plants release O2 to the atmosphere by taking CO2 (during day) as a part of carbohydrate synthesis. However during the night, the plants take oxygen through the opening of its stomata (respiration).
Option f. is given as, “both a and d”.
The macronutrients such as carbon, hydrogen, and oxygen are the essential elements required by the plants as they can obtain hydrogen from water and oxygen from the atmosphere (air).
Hence, the correct answer is option f.
Reasons for the incorrect answers:
Option a. is given as “macronutrients”.
The macronutrients are the nutrients that are required in higher amounts. They include carbon, nitrogen, oxygen, phosphorous, sulfur, potassium, hydrogen, and calcium. However, these nutrients are also the required elements for the plants.
Hence, option a. is incorrect.
Option b. is given as, “micronutrients”.
The micronutrients are the nutrients that are required in lesser amount. They include zinc, copper, boron, chlorine, manganese, iron, and molybdenum. These do not include carbon, hydrogen, and oxygen as they are macronutrients.
Hence, option b. is incorrect.
Option c. is given as, “trace elements”.
The chemical elements that is necessary only in small amounts by the organisms for their growth is known as trace elements. Carbon, hydrogen, and oxygen are required in higher amounts for the plants.
Hence, option c. is incorrect.
Option d. is given as, “required elements”.
Carbon, hydrogen, and oxygen are the essential elements for the plants but they are also the macronutrients.
Hence, option d. is incorrect.
Option e. is given as, “both a and b”.
Carbon, hydrogen, and oxygen are macronutrients that are required in higher amounts for the plants but they are not micronutrients.
Hence, option c. is incorrect.
Hence, options a., b., c., d., and e. are incorrect.
