Q2 · 1 mark · MCQHow do Organisms Reproduce?

Identify the type of reproduction shown in the diagram given below:

  1. (A)Budding
  2. (B)Fragmentation
  3. (C)Spore Formation
  4. (D)Binary Fission

Figure in the paper: A sequence of amoeba-like single cells left to right: a cell with a nucleus gradually elongates, the nucleus divides into two, the cell constricts in the middle, and then splits into two separate daughter cells shown with arrows pointing to upper-right and lower-right. See it in the official paper.

Hints

Open one hint at a time and try again before the next.

Hint 1

Count how many daughter cells are formed and compare their sizes.

Hint 2

One cell dividing into two equal cells has a special name.

Step-by-step solution

Each step shows the marks it earns, as an examiner would award them. Checked by an independent re-solve from the question paper.

  1. The figure shows a single amoeba-like cell. Its nucleus divides into two, the cell constricts in the middle, and it splits into two equal daughter cells.

  2. A parent cell splitting into two equal halves is binary fission. Budding would show a small outgrowth, and spore formation would need sporangia. Correct option: (D).
