After completing this study unit you will be able to:
- Identify eukaryotic cells and name their contents.
- Recognize their individual cellular organelles.
The cell is the smallest, independently functioning unit of an organism. Eukaryotic cells are typically divided into cell membrane and cytoplasm. The cell membrane represents a barrier between the intracellular and extracellular spaces so that the exchange of substances between the cell and its environment can take place in a controlled manner. The cytoplasm is the fluid matrix of the cell. Here you can find the cytoskeleton and many different cell organelles.
The cytoskeleton is a network of filaments that gives the cell stability and allows it to move and transport cell components. The cell organelles are small cellular subunits, some of which are membrane-bound, and with their own very specific function. For example, the cell nucleus, which contains DNA (deoxyribonucleic acid) and mitochondria, which are essential for energy production in the organism, are particularly important here. Other major cell organelles include the endoplasmic reticulum, Golgi apparatus and lysosomes.
