• Cytokinesis in plant cells takes place by cell plate formation whereas in animal cells cytokinesis is accomplished by furrow formation.
• Plant cells have a rigid cell wall. So In-plant cell wall development begins in the middle of the cell and develops outward to connect the existing lateral walls.
• This involves the laying of a cell plate which characterises the middle lamella among the cell walls of adjacent cells.
• Cell plate develops centrifugally. Animal cells lack a cell wall. Hence cytokinesis involves the development of a furrow in the cell membrane. This grows centripetally and connects ultimately in the center of the cell and the cytoplasm is split into two.Answered by Pragya Singh | 1 year ago
Analyse the events during every stage of cell cycle and notice how the following two parameters change
(i) number of chromosomes (N) per cell
(ii) amount of DNA content (C) per cell
Can there be mitosis without DNA replication in the ‘S’ phase?
Discuss with your teacher about
(i) haploid insects and lower plants where cell-division occurs.
(ii) some haploid cells in higher plants where cell-division does not occur.
What is the significance of meiosis?
Distinguish anaphase of mitosis from anaphase 1 of meiosis.
