Facts About Cells
Every organism on the planet is made up of cells—without them life would not exists. There is a lot to know about cells, even though they are very small and it takes many to make up an organism. Cells are so small that a microscope is required in order to view them. Cells are so important to life that it seems only fair that we pay them some attention. Cells are very intriguing, and learning a little but about them can open up facts to other studies as well.
Types of cells
On the basic level, there are two different types of cells in existence. The cells that are found the most are called eukaryotic, and occur most often because they have a nucleus as part of their anatomy. The other type, prokaryotes, has only one single cell. You will find that plants and animals are eukaryotes, while organisms like bacteria are prokaryotes. Whether single-celled or multi, the cells that create organisms are complex and interesting.
Cells exist so that life can exist, but there is much more to them than that. Cells contain and pass of genetic information, which makes cells individual to each person they are part of. The cells contain chromosomes that determine things such as a person’s gender. Cells make up the genetic structure of who we are as individuals. In plants, cells require the energy from the sun to help aid in a flower’s function. Without that energy, cells would not be able to form the plant, help it grow, or produce the food that can come from different plants.
Cells don’t last forever, and when a cell experiences some type of damage, it will go ahead and destroy itself. A cell’s life can last anywhere from a day to a year, and the age of cells depends on the organ or organism within the body that the cell forms. When cells stop reproducing and replacing themselves, cancer can develop. The death of cells is required for the development of a human’s life.
