Question

Choose the incorrect statements.
A. Dark reaction of photosynthesis initiates by the fixation of $C{O}_2$ with Ribulose bisphosphate and results in the formation of 3C compound and finally into 6C glucose.
B. Organic and mineral nutrients undergo multidirectional transport from leaves to different parts of the plant.
C. Nastic movements are directional movement in which the direction of response is determined by plant structure.
d. in gymnosperms, the male and female gametophytes are released from the sporophytes for fertilization.
The incorrect ones are grouped in

• A. A and D
• B. C only
• C. C and D
• D. A and B

Answer 1

Answer: (C)

C and D

• The dark reaction of photosynthesis starts with glycolysis of RuBP 1, 5 biphosphates and results in the formation of a 3 carbon compound through the C3 cycle.
• Phloem helps in the transport of food from leaves to different parts of the body to obtain proper and enough nutrition.

So, statements A and B are correct.

• In nastic movements, the direction of movements is guided by the directional stimulus. For example, the opening of a sunflower at daytime and closing at night.
• in gymnosperms, male gametes (pollen grains) are carried to female gametes through the process of pollination after fertilization takes place
• So, statements C and D are incorrect

So, option C is the correct option.
