Imagine you are the nucleus of a plant or animal cell and have been asked to mentor an organelle that is new to the cell. Take y
Ivan

Hi,

I am Nucleus of the cell. I am the most important part of the cell and i have genetic material that is transferred to the offspring upon reproduction. I also supervise many important processes of cell like synthesis of proteins.

I will take you on the trip of our whole cell where you will be able to meet different organelles and know a little about their roles in cell. Let us meet them one by one:

1) Nucleolus: It is a darkish and roundish structure that resides inside me. Its role is in the synthesis of an important type of RNA called ribosomal RNA.

2) Nuclear membrane: This membrane surrounds me and is contains small pores for the movement of ribosomal RNA and proteins. Due to this surrounding DNA stays inside me and donot leaves me.

3) Golgi Complex: This is like a packaging and storing organelle of cell that processes and packs the proteins and exports them outsise or inside the cell. Their secretions include digestive glands, saliva, oils etc.

4) Rough Endoplasmic Reticulum: It consists of several long canals that form a series running throughout the cell and contains ribosomes attached with them. They are the organelles which transport proteins to the golgi complex for their packaging.  

5) Smooth Endoplasmic Reticulum: It has an important role in the detoxification process converting toxic substances into less toxic forms. They are in structure similar to rough endoplasmic reticulum except that they donot have ribosomes attached to them.

6: Centrioles: They are important in the process of cell division and are present in animal cells only.

7:Mitochondria: This is called as power house of the cell because all the processes that convert food into energy take place in this part. You can see it has two membranes outer is smototh while inner forms foldings.

8: Ribosomes and Free Ribosomes- They are freely floating in the cell or attached with endoplasmic reticulum, They have role in protein synthesis.

9: Lysosomes: They have an important function because they remove worn out and old organelles by digesting them. Therefore, they contain good digestive enzymes.

Hope it helps!
