List any three cell organelles and mention their functions
Answers
Answer:
#Plasma membrane
The plasma membrane (cell membrane) is the organelle that encapsulates the contents of the cell. Apart from encapsulating cell contents, the plasma membrane also plays a vital role in regulating the movement of substances in and out of the cell.
As such, it is actively involved in such both passive and active transportation to and from the cell. These processes also help maintain balance even when conditions outside the cell change.
The plasma membrane is made up of two layers of phospholipids (phospholipids bilayer).
#Nucleus / DNA:
Some of the main components of the nucleus include the chromatic, nucleoplasm/nuclear sap and the nucleolus.
* The nucleus houses DNA (the hereditary material) as well as various proteins and the nucleolus.
Answer:
Nucleus
Known as the cell’s “command center,” the nucleus is a large double membranous organelle that stores the cell’s DNA (deoxyribonucleic acid). The nucleus controls all of the cell’s activities, such as growth and metabolism, using the DNA’s genetic information. Within the nucleus is a smaller structure called the nucleolus, which houses the RNA (ribonucleic acid). RNA helps convey the DNA’s orders to the rest of the cell and serves as a template for protein synthesis.
Ribosomes
Ribosomes are the protein factories of the cell.It is membrane less organelle Composed of two subunits, they can be found floating freely in the cell’s cytoplasm or embedded within the endoplasmic reticulum. Using the templates and instructions provided by two different types of RNA, ribosomes synthesize a variety of proteins that are essential to the survival of the cell.
Endoplasmic reticulum
Endoplasmic reticulum. cell biology
Ribosomes on the outer surface of the endoplasmic reticulum play an important role in protein synthesis within cells.
The endoplasmic reticulum (ER) is a double membranous organelle that shares part of its membrane with that of the nucleus. Some portions of the ER, known as the rough ER, are studded with ribosomes and are involved with protein manufacture. The rest of the organelle is referred to as the smooth ER and serves to produce vital lipids (fats).
