binary fissionamoebacell division

Marking Scheme

  • 1Option A is the correct answer because it shows the correct sequence of events for binary fission in amoeba.
  • 2Option B is incorrect because it shows a different type of cell division.
  • 3Option C is incorrect because it shows a different type of cell division.
  • 4Option D is incorrect because it shows a different type of cell division.

Hint

Look for the diagram that shows the division of the cell into two equal halves.

Quick Oral Answer

Binary fission in amoeba involves the division of the cell into two equal halves. The process begins with the duplication of the nucleus, followed by the division of the cytoplasm. The resulting two daughter cells are genetically identical to the parent cell.

Analysis & Explanation

Binary fission is a type of asexual reproduction that occurs in unicellular organisms such as amoeba. It involves the division of the cell into two equal halves, resulting in two genetically identical daughter cells. The process begins with the duplication of the nucleus, followed by the division of the cytoplasm. Option A shows the correct sequence of events for binary fission in amoeba, making it the correct answer.

Common Mistakes

  1. 1Confusing binary fission with other types of cell division.
  2. 2Not recognizing the correct sequence of events for binary fission in amoeba.
