Short Essay On Cell Organelles

Cell Organelles

The largest cell organelle is the nucleus. Two membranes known as the nuclear envelope surround the nucleus. The outer membrane of the nuclear envelope is continuous with the endoplasmic reticulum. The nucleus and nuclear envelope are separated by a fluid, which contains a number of nuclear pores that are able to let large molecules through. The nucleus contains almost all of the cell’s genetic material. The nucleus has a substructure called the nucleolus. Messenger RNA (mRNA) must leave the nucleus to carry out protein synthesis.

The cell membrane is a thin structure that can also be known as the plasma membrane. The cell membrane encloses the contents of a cell and also controls the movement of particles in and out of the cell. Particles can move across the cell membrane in many different ways. For example, diffusion or active transport. A cell membrane can let some molecules mover from a lower concentration outside the cell to a higher concentration inside the

It gathers simple molecules and combines them to make molecules that are more complex. The Golgi body then packages the more complex molecules in vesicles. It then either stores them for later use or sends them out of the cell, the Golgi body is also the organelle that builds lysosomes. The job of a lysosome is to hold enzymes that were created by the cell. The purpose of a lysosome is to digest things. They could be used to digest food or even to break down the cell when it dies. It is a specialised vesicle that holds a variety of enzymes. Once a material is inside the cell, the lysosomes attach to it and release their enzymes. Sometimes, lysosomes start to digest the cell organelles for nutrients. Vesicles are packaged by the Golgi body and then they are either stored for later use or are sent out of the cell. Vesicles also build lysosomes. The vesicles are taken off the membranes and float throughout the
