How Do Cells Multiply

Asexual reproduction is another way to reproduce without sex. Where the children are the exact same as there parent. Basically they are cloning them self,  (making a identical copy of its self). asexual reproduction is fast, they can store lots of food and rapid growth, you only need one parent, and the good parts of there parents are passed on. but asexual reproduction has a, lack of spreading apart, adaption to environment is unlikely, and they inherit the bad parts of there parent.

sexual reproduction is when the sperm from a male fertilizes a females eggs (sex). this combines the attributes of both the parents. in sexual reproduction the new organism formed (the parent has given birth to it) with the mixed DNA of there parents and has the chance of not getting their parents diseases passed on, a new organism is formed, sex mixes their DNA together, and there is a good chance of a unique organism getting formed. there are still some bad parts to sexual reproduction, 2 parents must be involved, it takes longer, only 50% of the population can carry a fetus in the womb from conception to birth, having to find a mate and reproduce, the male sperm has to fuse with the female egg, parent could get a STD.

Mitosis is a process that takes 5 steps of cell division. two daughter cells each having the same kind of chromosomes and the parent nucleus. Interphase: In this phase the DNA duplicates in preparation for mitosis. Prophase:This is when the chromatin condenses into a X shaped structures called chromosomes  Metaphase: the cell’s chromosomes align themselves in the middle of the cell. Anaphase: in this the replicated chromosomes split and the daughter chromatids move to opposite sides of the cell. telophase and cytokinesis: the sister chromatids reach opposite sides. The small nuclear vesicles in the cell start forming around the chromosomes at each end and then the spindle fibres start to disappear, two nuclei are formed and the cells divide.

Mitosis is a 10 step process where a cell divides twice to produce four cells containing half the original amount of DNA. the four daughter cells only have half the number of chromosomes of the parent cell. The first step in meiosis is interphase, the second is prophase l, the third stage is metaphase l, the fourth stage is anaphase l, the fifth stage in meiosis is telophase l, the sixth stage is prophase ll, the seventh stage is metaphase ll, next is anaphase ll, then telophase ll, and then cytokinesis. The difference between mitosis and meiosis is that in mitosis it only ends in 2 organisms but in meiosis it ends in 4 organisms. another difference is that meiosis is longer than mitosis. the last difference is that the daughter cells in meiosis are not identical and in mitosis they are.

for an organism to grow it uses cell division to increases the number of cells in it, this is a process that is constantly going. in this process the cells grow big divide then die and the ones it produced divide and then die so that your always growing even when it looks like you haven’t, its just you losing some. The longer you live the stronger and bigger you get by cell division. as I said above when your cells duplicate they make two or 4 of them making a endless trail of cells. this is a form of mitosis.
