Quick Answer: What Does The Endoplasmic Reticulum Do Simple?

Why is a cell like a school?

The nucleolus is like a classroom because the nucleolus forms ribosomes, like a classroom forms students.

A cell membrane controls what is allowed to enter and exit into a cell, like a school cop controls what is allowed to go in and out of school..

What is the difference between rough ER and smooth ER?

The most basic difference between RER and SER is the presence of ribosomes. When ribosomes attach to the surface of an ER, it gives a characteristic rough appearance; hence it is called Rough ER. On the other hand, a smooth ER does not have ribosomes on its surface. It possesses ribosomes attached to its membrane.

What is a endoplasmic reticulum in a school?

Rough Endoplasmic Reticulum: The rough ER is like the school hallways because they transport proteins, just like the hallways are used for students to transport themselves between classes. … The smooth ER is like a school bus because it transports proteins, just like buses transports students to and from school.

What does the endoplasmic reticulum do quizlet?

endoplasmic reticulum- A system of membranes that is found in a cell’s cytoplasm and that assists in the production, processing, and transport of proteins and in the production of lipids.

What are the four major functions of the endoplasmic reticulum?

The ER is the largest organelle in the cell and is a major site of protein synthesis and transport, protein folding, lipid and steroid synthesis, carbohydrate metabolism and calcium storage [1–7].

What does the endoplasmic reticulum do?

The endoplasmic reticulum can either be smooth or rough, and in general its function is to produce proteins for the rest of the cell to function. The rough endoplasmic reticulum has on it ribosomes, which are small, round organelles whose function it is to make those proteins.

What can endoplasmic reticulum be compared to in a school?

Endoplasmic Reticulum (E.R.) The nucleus is like the principal of a school, because the nucleus controls the cell like the principal controls the school. 2. Ribosome- The site where amino acids are hooked together to make proteins.

What are the main functions of rough endoplasmic reticulum?

The endoplasmic reticulum can either be smooth or rough, and in general its function is to produce proteins for the rest of the cell to function. The rough endoplasmic reticulum has on it ribosomes, which are small, round organelles whose function it is to make those proteins.

Which are functions of smooth ER quizlet?

Does the Smooth Endoplasmic Reticulum create steroids? One of the primary functions of the Smooth Endoplasmic Reticulum is to produce and move lipids, an essential component of a cell’s outer membrane, and steroids.

What would happen if the rough endoplasmic reticulum lost all of its ribosomes?

Ribosomes are organelles that create proteins. Cells use proteins to perform important functions such as repairing cellular damage and directing chemical processes. … Without these ribosomes, cells would not be able to produce protein and would not be able to function properly.

What are the 3 main functions of the endoplasmic reticulum?

The endoplasmic reticulum (ER) serves important functions particularly in the synthesis, folding, modification, and transport of proteins.

What is the difference between SER and RER?

The main difference lies between the SER and RER is the presence of ribosomes, as SER do not have ribosomes but RER have ribosomes. SER mainly produce and export lipids and protein and function for detoxification, while RER produces, secrete and export proteins and few hormones.

What is the main function of ribosome?

Ribosomes have two main functions — decoding the message and the formation of peptide bonds. These two activities reside in two large ribonucleoprotein particles (RNPs) of unequal size, the ribosomal subunits. Each subunit is made of one or more ribosomal RNAs (rRNAs) and many ribosomal proteins (r-proteins).

The Cell Wall is like the beams in a school because it provides the school support. The Chloroplast is like the cafeteria in a school because it is where the students in a school get their energy. The Large Central Vacuole is like a swimming pool because it stores water for the swim team.
