Question

read part 1. jot down notes and drawings that will help you remember the meanings of these words. you can use the sketch/scribble button on the toolbar. mitosis type/draw here. diploid type/draw here. meiosis type/draw here. read it! mitosis and meiosis - part 1 in single celled organisms, cell reproduction gives rise to the next generation. in multi - cellular organisms, cell division occurs not just to produce a whole new organism, but for growth and replacement of worn out cells within the organisms. this process is called mitosis, and results in two daughter cells with nuclei that are identical to the original nucleus. these cells are diploid, meaning they have two copies of dna. meiosis on the other hand results in four daughter cells with nuclei that each have 1/2 the chromosomes of the original cell. this means the cells are haploid. meiosis only occurs in the cells that give rise to the sex cells called gametes. the genetic differences between the daughter cells in mitosis and meiosis is what makes these processes so important. for mitosis, the goal is to simply make new copies of the same cell. each new cell is a genetic copy of the old cell, a clone. in meiosis, however, the resulting daughter is genetically different. but how does this happen? in meiosis, during prophase the chromosomes can become tangled up as they pair up in preparation for metaphase. as a result, segments of the chromosomes, called alleles, are swapped or exchanged. when this happens, the genetic information is now shuffled, and at the end of

Explanation:

Mitosis is cell - division for growth and cell replacement in multi - cellular organisms, resulting in two diploid daughter cells (with two copies of DNA) that are genetically identical to the original cell. Meiosis occurs in cells that give rise to gametes, resulting in four haploid daughter cells (with half the chromosomes of the original cell) that are genetically different due to chromosome segment swapping during prophase. Diploid cells have two copies of DNA.

Answer:

Mitosis: Cell - division for growth and replacement, produces two genetically identical diploid daughter cells.
Diploid: Cells with two copies of DNA.
Meiosis: Occurs in gamete - producing cells, results in four genetically different haploid daughter cells.
