Mention five Organelles and write three functions of each.
Answers
More than 8.7 million species are living on the planet. Every single species are composed of a cell, and it includes both single-celled and multicellular organisms.
The cells provide shape, structure, and carries out different types of functions to keep the entire system active. The cell contains different functional structures which are collectively called as the Organelles, and they are involved in various cellular functions.
Answer:
Plasma Membrane.
Nucleus/DNA.
Ribosome.
Mitochondria.
Vacuoles.
Cytoskeleton.
Plastids.
Endoplasmic Reticulum
Explanation:
Ribosomes are tiny organelles that contain RNA and specific proteins within the cytoplasm. Within the cell, ribosomes are directly involved in the manufacture of proteins by using their RNA and amino acids.
This process involves decoding the information contained in the mRNA and using amino acids to produce the required proteins.
Mitochondria are some of the largest organelles within a cell.
Compared to some of the other organelles, mitochondria contain DNA which makes them semiautonomous. Mitochondria also contain a double-membrane with the inner membrane folding to form cristae.
Also known as the powerhouse, mitochondria play an important role in respiration where they generate ATP (adenosine triphosphate) from substrates in the presence of oxygen. Using their DNA, mitochondria are able to encode for some of the components they require to perform their functions.
ER----->
Found in eukaryotic cells, Endoplasmic reticulum (ER) is the organelle that forms an interconnected network of flattened sacs (cisternae). Like some of the other organelles found in eukaryotes, ER is enclosed in a membrane. The ER is divided into two regions that vary in structure and function.
These include:
Smooth endoplasmic reticulum - The smooth ER is named so because it lacks a ribosome on its surface. As a result, it is more smooth in appearance as compared to the rough ER. It is involved in the synthesis of lipids (e.g. phospholipids) and carbohydrates that are used to build the cell membrane.
Some of the other functions of the smooth ER include:
Transportation of vesicles
Enzyme production in the liver
Contraction of muscle cells in the muscles
Synthesis of hormones in the brain cells
Rough endoplasmic reticulum- Unlike the smooth ER, rough ER has ribosome attached to its surface. It's involved in the manufacture of various proteins in the cell. On the other hand, the rough ER is involved in the production of antibodies, insulin as well as transportation of proteins into the smooth ER.
