Q. Consider the following statements about different types of cells:
1.The somatic cells are diploid cells containing two pairs of chromosomes.
2.The stem cells can be divided through mitosis.
3.The gametes are an organism’s reproductive cells.
Which of the statements given above are correct?
Answer: D
Notes:
Explanation: All Statements are correct
Statement 1 is correct: Somatic cells are diploid cells, which contain two pairs of chromosomes, one received from each parent.
Statement 2 is correct: Stem cells are body’s raw material, i.e. cells from which all other cells with specialized functions are generated. They can divide through mitosis –> single cell divided into two identical daughter cells.
Statement 3 is correct: A cell whose nucleus unites with that of a cell of the opposite sex to form a new organism –> reproductive cell. Gametes are an organism’s reproductive cells –> sex cells.
