Cell Cycle IB Biology: Complete Explanations

Cell Cycle IB Biology is the series of events that occur in a place called a cell. It is then resulting in a duplication of the DNA and the division of cytoplasm. This series of events occurring in a cell is an important one. 

A change in a body and a caterpillar turning into a butterfly is an example idea of a life cycle. Humans and other organisms are also going through the same life cycle. It is a series of development that goes on from one to another from when they are born until they reproduce. 

Cells also need to divide for the body to grow and regenerate itself. Understand it further by reading this article. 

Why Do Cells Need to Divide?

The cell cycle is a series of developmental steps from birth to reproduction. It is important for cells to grow and reach certain steps. In order to do so, cells need to divide themselves. 

Cells will need to divide themselves for the body so it can show further growth. Cells also divide to regenerate themselves to repair their body tissue. When a cell divides itself, the outer membrane will keep pinches inward. This happens until the new cells that are in the process of forming separate themselves. The process will eventually produce two new cells (daughter) from one cell (parent). 

The content of the parent cells will be copied and then divided into the two daughter cells. Before that, the nucleus of the parent cells need also to divide. The division of the nucleus is important in normal cell division. That is because it will ensure that the daughter cells will have the same genetic information as the parent cell. 

What Happens When Cells Don’t Divide?

In cell cycle IB Biology, cell division is the key to life. It is with the cell cycle we can continue to change and grow. For our bodies to grow and change, cells need to produce new cells. This will allow the old cells to die. 

Cell division is also essential when you are encountering injury. Cell division will allow bodies to produce new skin cells and heal the injury. Without cell division, you cannot grow fingernails back, heal from an injury or even reproduce. 

Moreover, a cell division that goes wrong will give dramatic results. Repeated rounds of unregulated cell division will lead to minor conditions in the body to major conditions like cancer. 

Cell division takes place in multiple stages and a strict cycle. Cell division that is not taking place in a being’s body will not allow them to reproduce. It will end the life cycle of a species. 

What is the cell cycle IB Biology?

A life is to move forward and change. This change and growth is happening in our body too without you knowing. The growth is happening from our cells to ensure that development will occur. 

A cell that wrongly develops and goes awry, will result in a certain condition from minor condition to major condition like cancer. Hence, the cell cycle is an important part of our body. 

Cell cycle IB Biology is to learn the life cycle of beings. All living beings consist of a diverse collection of cells. The cell cycle will function so it can carry out essential functions in a cell such as immunity, growth, and reproduction. 

Every cell will undergo a cell cycle. The cell cycle is happening to allow the parent cell so it can give the two daughter cells all of its information. 

Studying the life of the cell cycle will help research and discovery so it can result in treatments and cures of diseases of the cell cycle. Learning the cell cycle also allows you to understand how life becomes one and what will happen if the cell does not divide. 

Why is the cell cycle so important?

The cell cycle is part of your body that is important. A living being will most surely undergo this cycle to ensure life. A being that does not undergo a cell cycle will surely become unable to grow, develop, and reproduce. 

A being without a cell cycle will not be able to heal from injury, will not be able to bear a child, and will not be able to grow. As a result, this being will face extinction as a further result. 

This is why experiencing a normal cell cycle is important. It will allow you to grow from baby to adult. It will ensure that life will go on. 

A cell cycle that goes awry will cause a certain condition in the body. Disease or cancer is the exact example of disruption in the cell cycle. Hence, it is why cell cycle IB Biology is such an important matter. 

Two Phases of Cell Cycle  

Cell cycle IB Biology consists of two phases called interphase and mitotic phase. In the interphase, the cell cycle will go through additional sub-phases such as G1 or Gap 1, S or Synthesis, and also G2 or Gap 2. 

In the mitotic phase, the sub-phases consist of Prophase, Metaphase, Anaphase, and Telophase. Each phase and sub-phase is differentiated by the specific events of the molecule, like the below explanation.

Interphase

Interphase happens when cell growth and synthesis of DNA is happening. In this phase, there are cellular checkpoints to ensure the nutrient, transcription, and also translation. Of the important cell cycle components. 

• G1

Gap 1 is the first sub-phase of interphase. In this sub-phase the cell prepares to divide again and accumulates energy. It will also produce proteins that are required for the process of DNA replication.

• S

In the Synthesis sub-phase, the cell will synthesize a new copy of DNA. In this sub-phase the significant checkpoint is to check the DNA structure. 

• G2

Gap 2 happens when the cell organizes the genetic material and then prepares itself to divide. The cell will also continue the growth, accumulate nutrients, and then make sure the correct process is replication DNA. 

Mitotic Phase

The mitotic phase is when cell division is occurring. The sub-phases are prophase, metaphase, anaphase, telophase, and then cytokinesis when the cell division is final. 

• Prophase

The chromosomes will condense, divide into two chromatids, and then be joined by the centromere. It will then move to the opposite of the cell.

• Metaphase

In metaphase, chromatids align along the metaphase plate, anchored by centrioles, ready to be pulled apart by spindle fibers during cell division.

• Anaphase

In anaphase, the chromatids will split into two sister chromatids and they will become the daughter cells. 

• Telophase

In telophase, there is a process of indication of two new nuclear envelopes. It is formed around the chromosomes.

• Cytokinesis

In cytokinesis, the fell division is completed by physical separation of the components of cytoplasm and results in two daughter cells. 

Conclusion

Learning the cell cycle IB Biology will help you to understand the life cycle of organisms and humans. It is important to know how life should come into the world. Understanding life will give you the benefit of wisdom and knowledge.
