G₀ or quiescent phase is the stage wherein cells remain metabolically active, but do not proliferate unless called to do so. Such cells are used for replacing the cells lost during injury. For more answers visit to website: https://www.tiwariacademy.com/ncert-solutions/class-11/biology/chapter-10/

Interphase involves a series of changes that prepare a cell for division. It is the period during which the cell experiences growth and DNA replication in an orderly manner. Interphase is divided into three phases. 1- G1 phase 2- S phase 3- G2 phase G1 phase – It is the stage during which the cell gRead more
Interphase involves a series of changes that prepare a cell for division. It is the period during which the cell experiences growth and DNA replication in an orderly manner. Interphase is divided into three phases.
1- G1 phase
2- S phase
3- G2 phase
G1 phase – It is the stage during which the cell grows and prepares its DNA for replication. In this phase, the cell is metabolically active.
S phase – It is the stage during which DNA synthesis occurs. In this phase, the amount of DNA (per cell) doubles, but the chromosome number remains the same.
G2 phase – In this phase, the cell continues to grow and prepares itself for division.
The proteins and RNA required for mitosis are synthesised during this stage.
Cytokinesis:- (i) Cytokinesis is the biological process involving the division of a cell’s cytoplasm during mitosis or meiosis. (ii) It is divided into four stages – prophase, metaphase, anaphase, and telophase. Karyokinesis:- (i) Karyokinesis is the biological process involving the division of a ceRead more

Karyokinesis:-
(i) Karyokinesis is the biological process involving the division of a cell’s nucleus during mitosis or meiosis.
(ii) Stages such as prophase, metaphase, anaphase, and telophase are not present in karyokinesis.
