Question

Describe the function of each organelle.

1- Nucleus
2- Ribosome
3- Endoplasmic reticulum
4- Golgi apparatus

Answer 1

nucleus: the center of the cell that contains the genetic material. The nucleus is like the "Brain" of the cell.
ribosome: is a large complex of RNA and proteins. Ribosomes are the cell structures that make protein. They are found in the endoplasmic reticulum.
endoplasmic reticulum: a network of tubular membranes in the cytoplasm. They fold protein molcules in sacs and transport these proteins in vesicles to the golgi apparatus.
Golgi Apparatus: stores and modifies proteins and prepares to transport them to different parts of the cell.

I hope this helps.

Answer 2

Answer and explanation;

Nucleus, Ribosome, Endoplasmic reticulum, and Golgi apparatus are among the cellular organelles that are tasked to different activities in a cell.

Nucleus;

• It is the control center of the cell. It controls all the activities and functions of a cell, such as cell metabolism and reproduction.
• Additionally; the nucleus contains the genetic material, that is, the DNA, which carries the information that is used to make proteins through the messenger RNA.

Ribosomes;

• Ribosomes are organelles that are either found suspended in the cytoplasm or attached to the rough enedoplasmic reticulum.
• They are sites for protein synthesis and carry out this fuction by assembling the amino acids in the apropriate sequences as instructed by the mRNA.

Endoplasmic reticulum;

• This is a network of membranous canals filled with fluid. They carry material through out the cells,
• They are two types; the rough endoplasmic reticulum and the smooth endoplamic reticulum.
• Rough ER is lined with the ribosomes, and helps in the transportation of proteins to the golgi apparatus.
• Smooth ER has no ribosomes, and functions in the making and transportation of lipids.

Golgi apparatus.

• They are also called golgi bodies. They are stacks of flattened membranous stacks.
• Their function is to process and package proteins. Golgi apparatus also synthesis lysosomes.
