1.Cell division serves as a means of reproduction in unicellular organisms through binary fission. In multicellular organisms, cell division aids in the formation of gametes, which are cells that combine with others to form sexually produced offspring.
2.Meiosis is a specialized form of cell division that produces reproductive cells, such as plant and fungal spores and sperm and egg cells. In general, this process involves a "parent" cell splitting into two or more "daughter" cells
3.Germ cells contain a complete set of 46 chromosomes (23 maternal chromosomes and 23 paternal chromosomes). By the end of meiosis, the resulting reproductive cells, or gametes, each have 23 genetically unique chromosomes. The overall process of meiosis produces four daughter cells from one single parent cell.
4.Cell division is the process by which a parent cell divides into two or more daughter cells. Cell division usually occurs as part of a larger cell cycle. ... Meiosis results in four haploid daughter cells by undergoing one round of DNA replication followed by two divisions.
From the given question the correct answer is:
1. What is the importance of cell division in organisms?
Answer :Cell division is necessary for the growth of organisms, repair of damaged tissues, healing and regeneration, and reproduction. Single-cellular organisms: reproduction. Cell division is the process by which a parent cell divides into daughter cells.
2.Where does meiosis cell division takes place in organisms? What is formed from the daughter cells in it?
Answer : Meiosis is a cell division in which four haploid cells are formed from a single diploid cell. It usually occurs in reproductive organs or gonads of the organisms. Meiosis is also known as reductional cell division because four daughter cells produced contain half the number of chromosomes than that of their parent cell.
3.A human cell has 46 chromosomes in it. What will be the number of chromosomes in its daughter cells if it undergoes through meiosis cell division?
Answer : Germ cells contain a complete set of 46 chromosomes (23 maternal chromosomes and 23 paternal chromosomes). By the end of meiosis, the resulting reproductive cells, or gametes, each have 23 genetically unique chromosomes. The overall process of meiosis produces four daughter cells from one single parent cell.
4.What is cell division?
Answer :
The division of a cell into two daughter cells with the same genetic material is called cell division.
