Explanation of Animal Cells (Part 2)
6. Lysosomes
Lysosome
Lysosomes are organelles in the form of bags attached to membranes that contain hydrolytic enzymes. It is used to control intracellular digestion in any condition. Lysosomes are found in eukaryotic cells.
Lysosomes have the following functions:
To control intracellular digestion.
As digesting material using phagocytosis.
As the destruction of organelles that have been damaged (autophagi).
As the introduction of macromulecules from outside into the cell with.
7. Peroxisomes (Micro Bodies)
Peroxisomes of Micro Bodies
Peroxisomes are organelles that have small pockets filled with the enzyme catalase. This function serves to decipher peroxide (H2O2) or metabolism that is toxic. Which can change water and oxygen that are harmful to cells. Peroxisome organelles are commonly found in liver and kidney cells.
This organelle has the following functions:
The change from fat to carbohydrate.
Describes peroxides (H2O2) from toxic metabolic remnants.
8. Ribosomes
Ribosome
Ribosomes are cell organelles that have a dense and small texture with a diameter of 20 nm. This organelle consists of 65% ribosomal RNA (rRNA) and 35% ribosomal protein (Ribonucleoprotein or RNP). Ribosomes work as translating RNA to form polypeptide chains (proteins) using amino acids during the translation process.
In ribosome cells are bound to be in the rough endoplasmic reticulum (REk), or cell nucleus membrane. Ribosomes have a function as a place for the process of protein synthesis.
9. Sentriol
Sentriol
Sentriol is an organelle structure that has an organelle tube shape which can be found in eukaryote cells. These organelles can also play a role in cell division and in the formation of cilia and flagella. In addition, a pair of centrioles can form a combined structure called the centrosome.
Sentiol has functions as:
Serves as forming cilia and flagella.
As a process of cell division in forming spindle threads.
10. Microtobules
Microtobulus
Microtubules are cell organelles found in the cytoplasm and can be found in eukaryotic cells. These organelles are long cylindrical shapes that are hollow. This organelle has a diameter of approximately 12 nm and an outside diameter of 25 nm. Apart from animals, organelles are also owned by plant cells which are exactly the same as animals.
Microtobules consist of globular globular protein molecules called tubulin. So that in an unconscious position these organelles are able to join to form cylindrical hollow in certain conditions. Besides microtobulus also has a rigid nature that can not change in shape.
This organelle has the following functions:
To protect cells.
Give cell shape.
Play a role in the formation of flagella, cilia and centrioles.
11. Golgi Body
Golgi Agency
Golgi bodies or golgi apparatus are organelles associated with cell excretion functions. Golgi bodies can be found in all eukaryotic cells. These organelles play an important role in having the function of excretion, such as the kidneys. Golgi body has a shape like a flat bag that is small to large and bound by a membrane. Each animal cell has 10-20 golgi bodies.
This organelle has the following functions:
To process protein.
Form lysosomes.
To form a plasma membrane.
Forms vesicles (sacs) for excretion.
12. Nucleus
Nucleus
The nucleus is a small organelle that regulates and controls cell activity. This process starts from metabolism to cell division. Nucleus contains genetic material in the form of long linear DNA that forms chromosomes.
These organelles can be found in eukaryotic cells and consist of parts such as the nuclear membrane, nuekloplasma, chromatin or chromosons, and the nucleus.
This organelle has the following functions:
Place of replication.
Store genetic information.
To maintain the integrity of genes.
Control metabolic processes in cells.
Control cell activity by managing gene expression.
13. Nucleole
Nucleolus
A nucleoli is an organelle that is in the nucleus of a cell or nucleus. These organelles are responsible for the formation of proteins using RNA or ribonucleic acid. This organelle has a function as being responsible for protein formation.
14. Nucleoplasm
Nucleoplasm
A nucleoplasm is an organelle that has a dense texture that is inside the nucleus of a cell or nucleus. This organelle contains chromatin fibers which are dense and form chromosomes. In addition this organelle is tasked to carry genetic information.
15. Core Membranes
Core Membranes
The nuclear membrane is the main structural element of the nucleus which encloses the whole organelle. Besides this organelle as a separator between the cytoplasm and the core region. These organelles are not permeable so most of the molecules that make the nucleus need a core pore. In this way the nucleus membrane is able to cross the membrane.
The core membrane has the following functions:
Protect the cell nucleus (Nucleus).
As a place to exchange substances between the core material and cytoplasm.
