Which cell division is responsible for the growth of tissue and individuals :–
1 Amitosis
2 Mitosis and meiosis
3 Meiosis
4 Mitosis
Explanation:
Mitosis usually results in the production of diploid daughter cells with identical genetic complement. The growth of tissue and individuals is due to mitosis.

Assertion : Cancer cells are virtually immortal until the body in which they reside dies. Reason : Cancer is caused by damage to genes regulating the cell division cycle.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Both Assertion and Reason are incorrect.
Explanation:
Cancer is caused by damage to genes regulating the cell division cycle. It results due to an uncontrolled growth of the cells. The cancer cells show uncontrolled cell growth. They have lost their cell differentiation ability. The also do not exhibit contact inhibition anymore. All these factors make the cancer cells immortal. Hence, these are virtually immortal cells until the body in which they reside dies.

Which of the following is not a characteristic feature during mitosis in somatic cells?
1 Chromosome movement
2 Synapsis
3 Spindle fibres
4 Disappearance of nucleolus
Explanation:
Synapsis is the process of association of homologous chromosomes. It takes place during zygotene stage of prophase I of meiosis. This stage is not seen during mitosis.

Statement A : In animals, mitotic cell division is only seen in the diploid somatic cells with few exceptions. Statement B : In plants, mitotic divisions is seen in both haploid and diploid cells.
1 Statement-A is correct but Statement-B is incorrect.
2 Statement-A is incorrect but Statement-B is correct.
3 Both Statements are correct.
4 Both Statements are incorrect.
Explanation:
In animals, mitotic cell division is only seen in the diploid somatic cells. However, there are few exceptions to this where haploid cells divide by mitosis, for example, male honey bees. Against this, the plants can show mitotic divisions in both haploid and diploid cells.

Mitosis usually results in the
1 Production of diploid daughter cells
2 Growth of multicellular organisms
3 Production of haploid daughter cells
4 All of the above
Explanation:
Mitosis is exhibited by diploid cells with a few exceptions (Haploid - lower plants, social insects). Mitosis usually results in the production of diploid daughter cells with identical genetic complement. The growth of multicellular organisms is due to mitosis.
