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
Which of the following statements is True?
(1) Cell plate represents the middle lamella between the walls of two adjacents cells
(2) At the time of cytokinesis, organelles like mitochondria and plastids get distributed between the daughter cells
(3) Cytokinesis in plant cell is centrifugal and takes place by cell-plate formation while animal cells by furrowing / cleavage and is centripetal
(4) All are correct
Mark the correct statement:
1 The stage between two successive meiotic division is generally long lived
2 In plant cells, wall formation starts in the centre of the cell and grows outward to meet the existing lateral walls
3 Meiosis results in conservation of specific chromosomes number of each species across generations in asexually reproducing organisms
4 Telophase - I can last for months or year
Identify the symbols A, B and C in the figure given below
| A | B | C |
(1) | G0 | Prophase | Cytokinesis |

Cytokinesis in animal cell takes place by _______; in _______ direction while in plant cell by _______; in _______ direction:
(1) Furrowing, centrifugal, cell plate, centripetal
(2) Furrowing, centripetal, cell plate, Centrifugal
(3) Cell plate, centrifugal, furrowing, centripetal
(4) Cell plate, centripetal, furrowing, centrifugal
The end of which of the following mark's completion of Mitosis?
1. Cytokinesis
2. Karyokinesis
3. Interkinesis
4. Telophase
Plant cells do not divided their cytoplasm by forming a furrow in cell membrane like animal cells rather they divide by cell plate because
(1) Plant cell do not have centrioles
(2) Cell wall formation beings with formation of cell plate
(3) Cell plate represents middle lamella between the walls of two adjacent cells
(4) Plant cells are enclosed by a relatively inextensible wall
