The nucleolus also known as the nucleole is the darker circle in the center of the nucleus. Just like any other organelle it is very important.
The structure of this unique organelle is very complex. This organelle is a non-membrane structure. The structure of this non-membrane structure is composed of proteins and nucleic acids. The nucleolus usually will get the proteins and nucleic acids from the nucleus. Ribosomal RNA is also assembled in the nucleolus. There are also three main components to the nucleolus. These three components consist of the fibrillar centers (FC), the fibrillar component that is dense (DFC), and granular components (GC).
In the nucleus the volume that is taken up by the nucleolus consists of 25%. The main function that the nucleolus is responsible for is to rewrite ribosomal RNA and combine it with proteins. This combined substance will then be turned into DNA.

Ribosomes
Typically for ribosomes there are two location that you can find. One is usually suspended in the cytosol and the other is usually bounded to the endoplasmic reticulum. These two ribosomes are called free ribosomes and bound ribosomes.
These special little ribosomes are found in both prokaryotes and eukaryotes. The structure to ribosomes are somewhat simple. The structure of ribosomes are composed of mRNA and polypeptide chains. These two together then form a polysome structure. The ribosomes main functions consist of assembling amino acids to make a specific protein and producing proteins.

Lysosomes
Lysosomes these little digustive miracles are found scattered throughout the cytoplasm. Cytoplasm is located near the nucleus so therefore so whould the lysosomes. Lysosomes are also found in nearly every animal cell.
The structure of a lysosome is basically just a specialized vesicle. This vesicle usually just holds a wide variety of enzymes. The enzymes inside this vesicle are made in endoplasmic reticulum. These proteins are then packaged and sent to the Golgi apparatus. The main function of lysosome is to digest food. When the cell absorbs or eats food the lysosome will attach to this material and release an enzyme. These little miracle workers still will work even if there is no food in the cell.

Mitochondria
Mitochondria are strong little producers of energy. The mitochondria is normally not located in one place. Usually you will find the mitochondria floating freely throughout the cell. The known exact place of mitochondria are found in muscles because they need the energy.
Mitochondria is composed of double-membrane. The outer membrane of the mitochondria is made of a bilayer of phospholipids that contain protein structures called porins. The inner membrane is a very complex structure. These two membranes then create Intermembrane space. Matrix and crista are also present. Mitochondria's main function is to produce energy. It also helps with building certain parts of the blood, and also helps with building hormones. Organelle works with: the cell |
