Title: Mitosis and amount of time spent in each phase. Introduction: The cycle of a cell roughly doubles it volume of cytoplasm and duplicates its genetic information i.e. replicated DNA. Then it divides the genetic information equally into two daughter nuclei. The cell cycle can be divided into two phases interphase and mitotic phase. The time spent in these phases depends upon the type of cell and its particular developmental or physiological state. Cells comprising rapidly growing tissues

An important step of the cell cycle is called mitosis‚ in which the cell (referred to as the parent cell) undergoes a series of steps that lead to the formation of two daughter cells. This process only occurs in somatic cells‚ which are any non-gamete cells. Gametes are haploid (containing only half of a full

The larger a cell becomes‚ the more demands the cell places on its DNA. In addition‚ a large cell is less efficient in moving nutrients and waste material across the membrane. 1b. As a cell’s size increases‚ what happens to the ration of its surface area to its volume? As a cells size increases‚ the volume increases more than the surface area. However‚ the ratio

Meiosis How does sexual reproduction lead to genetic variation? Why? Cells reproduce through mitosis to make exact copies of the original cell. This is done for growth and repair. Sexually-reproducing organisms have a second form of cell division that produces reproductive cells with half the number of chromosomes. This process is called meiosis‚ and without it‚ humans‚ oak trees‚ beetles‚ and all other sexually-reproducing organisms would be vastly different than they are today. Model
