Question

Study the following and pick up the correct statements:
I. As the binary fission in Paramecium occurs parallel to longitudinal axis of the body, it is called homotheogenic fission.
II. As the daughter Paramecia formed after binary fission are like mirror images, the fission is called symmetrogenic fission.
III. Multiple fission in Amoeba is called sporulation.
IV. Union of pronuclei of the gametes is called amphimixis.

• A. I, II
• B. II, III
• C. III, IV
• D. I, III

Hint:

Understanding different types of cellular reproduction is fundamental in microbiology and can help elucidate how genetic diversity is achieved in simple organisms.

Answer 1

The Correct Option is C

To solve the problem, we need to analyze the given statements about binary fission and select the correct ones.

1. Analyzing the Statements:

Statement I: "As the binary fission in Paramecium occurs parallel to the longitudinal axis of the body, it is called homothetogenic fission." This statement is incorrect. The correct term is "binary fission," not "homothetogenic fission."
Statement II: "As the daughter Paramecia formed after binary fission are like mirror images, the fission is called symmetrogenetic fission." This statement is incorrect. The correct term is "binary fission," and the daughter cells are typically identical, not mirror images.
Statement III: "Multiple fission in Amoeba is called sporulation." This statement is correct. In Amoeba, multiple fission is indeed called sporulation, where the organism forms spores.
Statement IV: "Union of progametes in the gametes is called amphimixis." This statement is correct. Amphimixis refers to the fusion of gametes during sexual reproduction, which is an essential process in many organisms.

2. Analyzing the Correct Combination:
The correct statements are III and IV.

Final Answer:
The correct option is (C) III, IV.
