Alborosie

Answer:

The correct statements are:

  • Meiosis results in four haploid daughter cells.  
  • During meiosis, the 2N mother cells produce N daughter cells.  
  • In both processes, DNA replication must occur.  
  • Mitosis is responsible for genetic continuity; in higher organisms, it is essential for growth and repair.  

Mitosis is a type of cell division in which a parent cell is divided into two identical daughter cells. Each daughter cell contains identical genetic material as that of the parent cell.  

It plays important role in growth and repair of cells and tissues in multi-cellular organisms.

Meiosis is a type of cell division in which a parent cell is divided to produce four daughter cells. Each daughter cell contains exactly half the genetic material (chromosomes) as that of parent cells

It plays important role in the production of gametes (eggs and sperms) in sexually reproducing organisms.

Before either cell division, the DNA is replicated in the S or synthesis phase of the cell cycle.
