Q. No.The furrow gradually deepens and ultimately joins in the centre dividing the cell cytoplasm into two. Here, the cell is
1.
Animal cell
2.
Plant cell
3.
Both A and B
4.
Only Root tip cells
The Cytokinesis of plant cell is not same as that of animal cell because of
| 1. | Inextensible cell wall |
| 2. | Cell membrane differences |
| 3. | Intermediate Filaments |
| 4. | Nuclear envelope |
The simple precursor of cell wall in plant cell is
1. Cell plate
2. Cell sap
3. Cell membrane
4. Cytosol
If Karyokinesis is not followed by Cytokinesis
| 1. | Multinucleated |
| 2. | Syncytium |
| 3. | Liquid endosperm in coconut |
| 4. | All of these |
Mitosis doesn't occur in
| 1. | Diploid cell |
| 2. | Haploid cell of lower plants |
| 3. | Haploid cell of social insect |
| 4. | Haploid cell of animals |
Mitosis results in
| 1. | Diploid daughter cells |
| 2. | Cells of identical genetic complement |
| 3. | Both A and B |
| 4. | Haplo- Diploidy |
Mitosis doesn't perform which of the following functions?
| 1. | Cell repair |
| 2. | Growth of multicellular animals |
| 3. | Restoration of nucleus to cytoplasmic ratio |
| 4. | Continuation of cell growth |
Which of the following cells are not constantly replaced?
| 1. | Blood cells |
| 2. | Cells of inner lining of gut |
| 3. | Brain cells |
| 4. | The cells of the upper layer of Epidermis |
Mitotic divisions which result in continuous growth of plants throughout their life
| 1. | In the meristematic tissue |
| 2. | Apical and lateral cambium |
| 3. | Both A and B |
| 4. | Cells of maturation zone of root |
The specialized kind of cell division that reduces the chromosome number by half results in the production of haploid phase in the life cycle is
1. Meiosis
2. Mitosis
3. Amitosis
4. Karyomitosis
