Mitosis & Meiosis

In science class this week, we've been learning about cell reproduction. What is Cell division? What is Mitosis? What is Meiosis? How are they alike? How do they differ? All of these amazing questions will be answered, if you decide to read on.

The Cell Cycle

A life cycle begins with an organism’s formation, followed by its growth and development, and the production of offspring that will repeat the cycle, before ending in death. Right now, I am in a stage in the life cycle called adolescence, which is a period of active growth and development. Similar to the life cycle, cells undergo a cycle too. It’s called the cell cycle. The cell cycle is a series of events that take place from one cell division to another.

A human life cycle and a cell cycle have many things in common. The main thing they have in common is that they’re both cycles. They both help in the areas of reproduction and growth. Although they have things in common, they also differ. One thing they have different is that at the end of a life cycle, the organism dies however; the cell cycle continues to reproduce. In the cell cycle, cells can reproduce asexually and sexually, but in the human cycle, humans reproduce sexually. This is how the cell cycle and the human cycle compare and contrast.

Cell Division

What is cell division? Well, cell division is the term that describes cell reproduction. Cell division is also the process in which cells reproduce. In cell division, there are two ways cells divide: mitosis with body cells and meiosis with sex cells. Mitosis is the process in which the nucleus divides to form 2 identical nuclei. Each new nucleus is also identical to the original nucleus. Mitosis is asexual reproduction. Asexual reproduction is the process in which one parent cell produces two daughter cells that are genetically identical to each other and the parent.

How do body cells divide? Well, body cells divide to multiply in the cell cycle. There...
