Read the following statements regarding diploid cell and identify the INCORRECT one. I. It can undergo a mitotic division to allow growth to occur. II. It can undergo a mitotic division to repair a cell. III. It can undergo a reduction division to form haploid cells. IV. It is the one that possesses two complete sets of chromosomes.
Options
- AAll except II
- BOnly II
- COnly I and III
- DOnly III and IV
Correct answer
B. Only II
Step-by-step solution
A cell having two sets of chromosomes is termed as diploid cell (statement IV) which produces haploid cell via meiosis (Statement III). Meiosis is the reductional division process where the chromosome number is halved in the newly formed daughter cells. Mitosis (equational division) usually results in the production of diploid daughter cells with identical genetic complement. The growth of multicellular organisms is due to mitosis. Mitosis produces genetically identical daughter cells. It is not useful in repair of
