Biology of a Human Cell: What Nobody Told You

What is the Biology of a Human Cell?

The biology of a human cell is the study of how cells are structured, what they do, and how they interact with their environment. These cells are responsible for all the processes that make up a human body.

Cells have changed over time and evolved to work more efficiently in different environments. They have also evolved to be more complex because of the need for better specialization when it comes to tasks such as respiration and digestion. This is why knowing the biology of a human cell is important because it helps us understand our own bodies better as well as understand our place in life on earth more completely.

The Reproductive Processes in a Cell: Mitosis, Meiosis, and Sexual Reproduction


Mitosis is an event in which the nucleus of a cell divides into two cells. In this process, each daughter nucleus contains the same DNA as the original nucleus.


Meiosis is also a nuclear division, but instead of just creating two new cells as in mitosis, meiosis results in four daughter cells with half the number of chromosomes and twice the amount of genetic variation. Sexual Reproduction:

Sexual reproduction is important because it allows for species to evolve and to create offspring that are genetically different from their parents.

The Parts of a Cell

The cell is the basic unit of life. It’s a microscopic structure that’s surrounded by a membrane and contains genetic material in the form of DNA. The human cell has the following parts:

It is made up of a cytoplasmic matrix, nucleus, mitochondria, and ribosomes.

Cytoplasm is the substance in the cell that holds all the other parts together. The nucleus is where DNA is found, and mitochondria converts energy into ATP. Ribosomes are what translate DNA into proteins so that they can be used by the cell for various purposes.

A cytoplasmic matrix consists of a combination of proteins, carbohydrates, lipids, and nucleic acids which make up most of the volume of a cell. All these substances form a gel-like matrix that surrounds every part in the cells including organelles such as mitochondria and ribosomes. The nucleus consists of a small group of chromosomes which carry genetic information for all living organisms. Mitochondria produce ATP or adenosine triphosphate which provides energy.

  • Cytoplasm is the liquid, jelly-like substance that fills the cell and its cavities. It contains many important structures like the nucleus, mitochondria, and ribosomes.
  • Cytoplasmic matrix – The cytoplasmic matrix is where proteins are synthesized. It also provides a scaffold for other proteins to be made.
  • Nucleus – The nucleus is the most central part of a cell where DNA strands are located and where all nuclear activity takes place
  • Mitochondria – Mitochondria are organelles that provide energy for cells. They take in nutrients from food and use it to produce adenosine triphosphate (ATP). Ribosomes – Ribosomes make proteins by combining amino acids into different sequences called polypept

What Happens to Cells When You Are Stressed

Stress is a natural, human response to events in the world around us. It can be emotional or physical. When we are stressed, our cells react by sending out “fight or flight” signals that will help us deal with the stress.

Do human cells get damaged by stress?

Stress has been known to cause a multitude of health problems and can lead to long term illness. A study carried out by the University of Calgary found that micro-tears in cells caused by chronic stress can lead to the development of diseases such as cancer.
