Cell structure and function in animal euokaryotic cell

An animal cell is the unit of creation for the animal kingdom. It definitely can't be seen unless you use a microscope. It is surrounded by a double layer membrane called plasma membrane which is mainly formed from phospholipids along with embedded proteins and cholesterol.

The plasma membrane unit consists of two sides, a hydrophobic one and a hydrophilic one. Inside the cell we can find a semifluid matrix called cytoplasm in which all the organelles of the cell and the molecules contained are floating. It's formed mainly from water.

In the center of the cell you can find the "cell brain and controller" which is the nucleus which is surrounded by a double layered membrane nuclear envelope in Eukaryotes. It contains all the chromatin material that hold the chromosomes that determine your genetic traits through a molecule called DNA.

Under a microscope you can find a dark spot inside the nucleus called the nucleus which participates in the formation of ribosomes. Ribosomes are non-membranous organelle that are involved mainly in protein formation inside the cell. 

Other important organelles inside the cell are SER and RER, smooth and rough endoplasmic reticulum. Rough endoplasmic reticulum holds ribosomes on its surface so it's involved in protein formation, while SER is involved in lipid formation. You can also find the centrosome which consists of  two centrioles which play an important role in the formation of the spindle fibers during cell division.

Mitochondria is the powerhouse of the cell in which cellular respiration occurs and it produces a great amount of ATP which is the energy currency in the cell. Lysosomes, Golgi body and vacuoles are also found in the cell.
