Question

Plz friends do answer. I'll also follow u if u answer right​

Answer 1

1.G1 phase is also known as Gap 1 phase. It is the first sub-phase in the interphase of the cell cycle that is seen in eukaryotic cell division. In this phase, messenger RNA (mRNA) and proteins are synthesized in the cell for the preparation of mitosis. G1 phase is the longest phase of the cell cycle, whereas G2 phase or Gap 2 phase is the second sub-phase or stage of interphase in the cell cycle that further proceeds to mitosis. G2 phase follows the proper completion of S phase of the cell cycle during which the DNA of a cell is replicated. G2 phase is shorter as compared to G1 phase, and it further leads to prophase of mitosis.

2.Karyokinesis : Division of the nucleus during the cell cycle. Karyokinesis is usually followed by cytokinesis. 
Cytokinesis : The division of the cytoplasm to form two separate daughter cells immediately after mitosis. 

3.Mitosis consists of one stage whereas meiosis consists of two stages.

Mitosis produces diploid cells (46 chromosomes) whereas meiosis produces haploid cells (23 chromosomes).

Mitosis produces two identical daughter cells whereas meiosis produces four genetically different daughter cells.

4.tonoplast is the membrane surrounding a vacoule.and plasma membrane is a membrane surrounding a cell.
