Question

In binary fission two daughter euglena develop new flagella individually

• A. Both the statements I and II are correct
• B. Both statements I and II are false
• C. Statement I is correct. But II is false
• D. Statement I is false. But II is correct

Hint:

In *Euglena*, binary fission involves division along the long axis, with flagella division occurring as part of the process.

Answer 1

The Correct Option is B

In the process of binary fission in Euglena, the division involves the splitting of the organism into two daughter cells, and each daughter cell develops a new flagellum. However, the two statements provided are incorrect, as explained below:

• Statement I: "In binary fission, two daughter Euglena develop new flagella individually." This is false because, during binary fission in Euglena, the flagellum is divided, and the process of flagellum formation in both daughter cells happens differently, not individually as stated. Both daughter cells inherit part of the flagellum or its basal body, and no new flagellum develops separately.
• Statement II: "Longitudinal binary fission is seen in Euglena." This is false because the binary fission process in Euglena is indeed longitudinal. In longitudinal binary fission, the organism divides along the long axis. However, the statement is not well-phrased, making it incorrect as it does not specify that both flagella division and cellular division occur longitudinally along the axis of the organism.

Since both statements are false, the correct answer is Option (B).
