Question

Write short note on the folloiwng:-
(a) Golgi appratus (b) Mitochondria
(c) Lysosomes (d) SER; RER

Answer 1

Answer:

The Golgi apparatus, also known as the Golgi complex, Golgi body, or simply the Golgi, is an organelle found in most eukaryotic cells.[1] It was identified in 1897 by the Italian scientist Camillo Golgi and named after him in 1898.[2]

Part of the endomembrane system in the cytoplasm, the Golgi apparatus packages proteins into membrane-bound vesicles inside the cell before the vesicles are sent to their destination. The Golgi apparatus resides at the intersection of the secretory, lysosomal, and endocytic pathways. It is of particular importance in processing proteins for secretion, containing a set of glycosylation enzymes that attach various sugar monomers to proteins as the proteins move through the apparatus.

Lysosomes are also found in the cytoplasm. They have more of a sac like stucture that is surrounded by a single membrane that contains very powerful digestive enzymes. The function od Lysosome is to break down dying cells, organelles, even toxins, and food particles.

Mitochondria are organelles that are scattered throughout the  

cell, all cells have mitochondria. This is where chemical reactions occur that transfer energy from organic compounds to ATP. ATP controls most of the reactions that occur inside of the cell. Mitochondria is surrounded by two membranes. Mitochondria have their very own DNA, and new mitochondria are born when  

existing ones grow and divide.

I CANT SAY ABOUT SER AND RER SORRY!!!!!!

Answer 2

(A) GOLGI APPARATUS:

The Golgi apparatus, also called Golgi complex or Golgi body, is a membrane-bound organelle found in eukaryotic cells (cells with clearly defined nuclei) that is made up of a series of flattened stacked pouches called cisternae. It is located in the cytoplasm next to the endoplasmic reticulum and near the cell nucleus.

(B) MITOCHONDRIA:

Mitochondria are known as the powerhouses of the cell. They are organelles that act like a digestive system which takes in nutrients, breaks them down, and creates energy rich molecules for the cell. The biochemical processes of the cell are known as cellular respiration.

(C) LYSOSOMES:

A lysosome is a cell organelle. ... Lysosomes work like the digestive system to break down, or digest, proteins, acids, carbohydrates, dead organelles, and other unwanted materials. They break up larger molecules into smaller molecules.

(D)

SER:

The smooth endoplasmic reticulum (smooth ER) is a membranous organelle found in most eukaryotic cells. ... Its main functions are the synthesis of lipids, steroid hormones, the detoxification of harmful metabolic byproducts and the storage and metabolism of calcium ions within the cell.

RER:

Rough endoplasmic reticulum (RER), series of connected flattened sacs, part of a continuous membrane organelle within the cytoplasm of eukaryotic cells, that plays a central role in the synthesis of proteins. ... RER occurs in both animal and plant cells.
