How Cells Multiply

In this post I will show me knowledge of asexual reproduction, sexual reproduction, and the stages of mitosis.

Asexual Reproduction

Asexual Reproduction is when a organism can create offspring without the need of a other organism. The offspring is always genetically identical to the parent.

 

Some of the good things about asexual reproduction include :

  • No energy required to find a mate.
  • Can reproduce large amounts of offspring quickly.

Only one parent is needed to produce offspring.

 Disadvantages

 

  •  If the parent has a mutation, all offspring will have the same mutation.
  • Can be hard for the offspring to adapt if they are born in different conditions than the parent is used to.
  • Overpopulation could be an issue.

 

Sexual Reproduction

Sexual Reproduction is when two parents are need to create offspring. The offspring is more than not similar to the parents, getting a X and Y chromosome from each parent. But develop their own features also.

 

Advantages

 

  • The offspring can adapt to the environment around them

If one parent has a mutation the offspring has a chance to not be affected by the mutation.

 

Disadvantages

 

  • Sometimes lots of time and energy are needed to find a mate.
  • Can not reproduce as fast as asexual organisms.
  • Although the chance is lower, mutations can still be passed to offspring through sexual reproduction.

 

Mitosis Stages

Mitosis, is used in asexual reproduction                                                                                                    .Image result for mitosis Cell cycle"

Meiosis is used in sexual reproduction.

The cell cycles for Mitosis and Meiosis are similar but not quite the same.

With mitosis, the daughter cells are genetically identical to the parent cell. Which has some disadvantage and advantages as I have stated above.

With meiosis the daughter cells are a mix of the two parents cells. This also has different advantages and disadvantaged as I have stated above.

Growth of organisms.

You and me, right now, are growing. Organisms grow because of mitosis and meiosis. But in me and you, meiosis is going on. Our cells are multiplying at a supersonic rate, everyday billions of cells are made and billions of cells die. The very reason we get taller, and mature is because of our cells rapidly multiplying within our body.

 

I’m aware this is late but please mark it.
