At the time of cytoplasmic division, organelles like ______ and plastids get distributed between the two daughter cells
2 of 15
In some organisms karyokinesis is not followed by cytokinesis as a result of which ______ condition arises leading to the formation of syncytium (e.g., liquid endosperm in coconut).
3 of 15
Mitosis or the equational division is usually restricted to the ______ cells only. However, in some lower plants and in some social insects ______ cells also divide by mitosis.
4 of 15
Mitosis usually results in the production of diploid daughter cells with identical ______ complement.
5 of 15
The growth of multicellular organisms is due to mitosis. It very significant contribution of mitosis is ______ . The cells of the upper layer of the epidermis, cells of the lining of the gut, and blood cells are being constantly replaced.
6 of 15
Cell growth results in disturbing the ratio between the nucleus and the cytoplasm. It therefore becomes essential for the cell to divide to restore the ______ ratio.
7 of 15
Mitotic divisions in the meristematic tissues-the apical and the ______, result in a continuous growth of plants throughout their life.
8 of 15
______ is the production of offspring by sexual reproduction includes the fusion of two gametes, each with a complete haploid set of chromosomes.
9 of 15
Gametes are formed from specialised diploid cells. This specialised kind of cell division that reduces the chromosome number by ______ results in the production of haploid daughter cells.
10 of 15
Meiosis ensures the production of haploid phase in the life cycle of sexually reproducing organisms whereas ______ restores the diploid phase
11 of 15
meiosis during ______ in plants and animals. This leads to the formation of haploid gametes.
12 of 15
The key features of meiosis are as follows: • Meiosis involves two sequential cycles of nuclear and cell division called meiosis I and meiosis II but only a single cycle of DNA replication. • ______ is initiated after the parental chromosomes have replicated to produce identical sister chromatids at the S phase.
13 of 15
The key features of meiosis are as follows: • Four ______ cells are formed at the end of meiosis II
14 of 15
Prophase I: Prophase of the first meiotic division is typically longer and ______ when compared to prophase of mitosis
