Consider the following statements: 1. Meiosis is a process where a single cell divides into two identical daughter cells. 2. Mitosis is a process where a single cell divides twice to produce four cells. Which of the following statements given above is/are correct?

Consider the following statements: 1. Meiosis is a process where a single cell divides into two identical daughter cells. 2. Mitosis is a process where a single cell divides twice to produce four cells. Which of the following statements given above is/are correct? Correct Answer Neither 1 nor 2

The correct answer is Neither 1 nor 2.

Key Points

• Meiosis is a process where a single cell divides twice to produce four cells containing half the original amount of genetic information. Hence statement 1 is incorrect.
  • During meiosis, one cell divides twice to form four daughter cells.
  • These four daughter cells only have half the number of chromosomes of the parent cell – they are haploid.
  • Meiosis produces reproductive cells- eggs in females and sperm in males.
• Mitosis is a process where a single cell divides into two identical daughter cells (cell division). Hence statement 2 is incorrect.
  • During mitosis, one cell divides once to form two identical cells.
  • The major purpose of mitosis is for growth and to replace worn-out cells.

Additional Information

• Cells are the basic structures of all living organisms.
  • Cells provide structure for the body, take in nutrients from food and carry out important functions.
  • Cells group together to form tissues, which in turn group together to form organs, such as the heart and brain.
• They contain a number of functional structures called organelles.
  • These organelles carry out tasks such as making proteins, processing chemicals and generating energy for the cell.
• The nucleus is based at the centre of the cell and is the ‘control room’ for the cell.
  • The genome is found within the nucleus.
