The rosette habit of cabbage can be changed drastically to vine by the application of
Which of the following physiological effects is caused by gibberellic acid in plants?
Directions: The question consists of two statements: Assertion and Reason. While answering the question you are required to choose any of the following five responses.
(A) If both Assertion and Reason are true and the Reason is a correct explanation of the Assertion; (B) If both Assertion and Reason are true, but Reason is not a correct explanation of the Assertion; (C) If Assertion is true, but the Reason is false; (D) If Assertion is false and Reason is true; (E) If both Assertion and Reason are false. Assertion: Glycolysis begins in the cytoplasm, resulting into two C-3 intermediates, then rearranges further to yield two molecules of pyruvate. Reason: During glycolysis, four ATP and two NADPH molecules are produced and the net yield is only two ATP molecules.If the CO2 content of atmosphere is as high as 300 parts per million, then
Ribulose–1, 5 diphosphate carboxylase is the initial enzyme of
What is the reason for the appearance of drought spots in apples?

Assertion (A): Of the wide range of wavelengths in the electromagnetic spectrum, plants can use only visible light for photosynthesis. Reasoning(R): About 48% of the energy in solar radiation reaching plants is in the form of ultraviolet and infrared light and these are not used in photosynthesis.
Directions: The question consists of two statements: Assertion and Reason. While answering this question, you are required to choose any one of the following five responses.
(A) If both Assertion and Reason are true and Reason is the correct explanation of Assertion; (B) If both Assertion and Reason are true but Reason is not the correct explanation of Assertion; (C) If Assertion is true but Reason is false; (D) If Assertion is false but Reason is true; (E) If both Assertion and Reason are false.
Assertion (A): Both blue and red lights are used directly for light reactions of photosynthesis. Reason (R): The absorption spectrum represents the graph plotted between the amount of CO2 consumed and different wavelengths of light absorbed by the same pigment.
Directions: The question consists of two statements : Assertion and Reason. While answering the question you are required to choose any one of the following five responses. (A) If both Assertion and Reason are true and the Reason is a correct explanation of the Assertion (B) If both Assertion and Reason are true but Reason is not a correct explanation of the Assertion (C) If Assertion is true but the Reason is false. (D) If Assertion is false and Reason is true. (E) If both Assertion and Reason are false.
Assertion: C4 plants are capable of photosynthesizing under very low CO2 concentration. Reason: RuBP carboxylase is present in them.
