What happens when the cell is without DNA


A cell in the biological sense is the smallest living unit of an organism or organ. All living things are made up of cells. Living beings that consist of only one cell are called Unicellular organisms. This can be bacteria, fungi or algae. Multi-cell consist of several cells. There are estimates that a person from 30 trillion (30 * 1012) Cells.

Not all cells are created equal. Cells that contain a nucleus are called eukaryotic cells and the living beings that are made up of such cells are called Eukaryotes (also eukaryotes). Cells without a nucleus are prokaryotic cells and the organisms that consist of such cells are called Prokaryotes (also prokaryotes). Prokaryotes always consist of one cell, i.e. they are single-celled cells, while eukaryotes can be single-cell or multi-cellular.

The cell can be thought of as a balloon filled with water. Inside the balloon in eukaryotic cells there is a second smaller balloon, the Cell nucleus. This is where the DNA is located. Prokaryotes do not have a nucleus and the DNA is exposed in the cell.

Different tissues in a living being are made up of different cells. For example, your skin is made up of a different type of cell than your heart.

Plant and animal cells are both eukaryotic cells, but differ in their structure. Plant cells, for example, have a Cell wall. The cell wall protects the cell from bursting if too much water should penetrate. It also supports the cell. In addition, plant cells have Chloroplasts. Photosynthesis takes place here, i.e. the conversion of carbon dioxide from the air into sugar and oxygen with the help of sunlight. The sugar supplies the plants with energy. Animal cells do not have a cell wall. They also do not contain chloroplasts.

However, both plant and animal cells have Mitochondria. Cell respiration takes place here, i.e. sugar is split and the released energy is used for the various cell functions.

The nucleus, chloroplasts and mitochondria are among the Cell organelles. Like organs in an organism, cell organelles fulfill various functions in the cell. Thanks to cell organelles, the cell can spatially separate various processes that could otherwise interfere with one another. Other cell organelles are the endoplasmic reticulum, the Golgi apparatus, the lysosomes, or the vacuole.
