What is the endoplasmic reticulum like in a computer?
The endoplasmic reticulum is like the folders in the computer because it stores information that you can use later. In the cell the endoplasmic reticulum stores and then transports particles across the cell. The folder stores information and then when needed can be used to move the data. …
What can the endoplasmic reticulum be compared to?
The endoplasmic reticulum creates a network of membranes found throughout the whole cell. These would be analogous to the stairs and hallways. They help us get from place to place.
What is an analogy for endoplasmic reticulum?
The endoplasmic reticulum is like the highway system because the cell uses the endoplasmic reticulum to move material throughout the cell like people use highways to move throughout the country.
How is the endoplasmic reticulum like 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 is the main function of endoplasmic reticulum?
The endoplasmic reticulum (ER) is a large, dynamic structure that serves many roles in the cell including calcium storage, protein synthesis and lipid metabolism.
What part of a school is like rough ER?
Both endoplasmic reticulum perform the same function, which is to transport materials produced in a cell. Therefore, in a school, both, the smooth and rough endoplasmic reticulum can be compared to the hallways. This is because hallways transport students and staff around the school.
What would a nucleolus be in a school?
The nucleolus is the dark spot in the middle of the nucleus where ribosomes synthesis takes place. The nucleolus of the school is the principal because the principal makes the rules just like the nucleolus makes the ribosomes. They make the food(energy) for the school. …
What does the ER do in a plant cell?
The endoplasmic reticulum (ER) is the port of entry of proteins into the endomembrane system, and it is also involved in lipid biosynthesis and storage.
What is rough endoplasmic reticulum in school?
Rough endoplasmic reticulum is an organelle found in eukaryotic cells. Its main function is to produce proteins. It is made up of cisternae, tubules and vesicles. The cisternae are made up of flattened membrane disks, which are involved in the modification of proteins.
Why is RER Class 9 rough?
Rough Endoplasmic Reticulum (RER) appears rough because of the presence of ribosomes on it. Ribosomes are sites for biological protein synthesis. Polyribosomes are aggregation of several ribosomes held together by a string of mRNA.
Why RER membrane is rough in nature?
RER – Rough Endoplasmic Reticulum. The rough endoplasmic reticulum is rough in nature because it has ribosomes embedded within its structure, which gives a rough appearance.
What is difference between rough and smooth endoplasmic reticulum?
The main difference between these two terminologies is that the Smooth Endoplasmic Reticulum is known for stocking the lipids and proteins. It is not bounded by ribosomes. Whereas, the Rough Endoplasmic Reticulum is bounded by the ribosomes and also stores proteins.
Why rough endoplasmic reticulum should be and is rough?
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 happens if rough ER is defective?
Without the RER the cell is not able to synthesis new plasma membrane proteins, lysosomal enzymes, proteines for the Golgi apparatus and proteins for extracellular secretion. The cell would no longer be able to produce ribosomes which are needed to make proteins.
What is the rough endoplasmic reticulum like in real life?
Thee proteins on the ribosomes collect in the Endoplasmic Reticulum to help transport the proteins throughout the cell. It is responsible for protein synthesis. A real life example of the Rough Endoplasmic Reticulum would be traffic on a highway.
In which cell would you find the most rough ER?
ROUGH ENDOPLASMIC RETICULUM These are called membrane bound ribosomes and are firmly attached to the outer cytosolic side of the ER About 13 million ribosomes are present on the RER in the average liver cell. Rough ER is found throughout the cell but the density is higher near the nucleus and the Golgi apparatus.
What happens if cytoplasm is defective?
If a cell would be without cytoplasm it could not retain its shape and would be deflated and flat. The organelles would not stay suspended in the solution of a cell without the support of cytoplasm.
What happens if a nucleus is defective?
If the nucleus is removed from the cell then the cell will not be able to function properly, it will not be able to grow. Without nucleus the cell will lose its control. It can not carry out cellular reproduction. Also, the cell will not know what to do and there would be no cell division.
What would happen if nucleus is removed from the cell?
If the nucleus of a cell is removed the cell will not be able to carry out its vital functions and will die.
What does cytoplasm look like?
Cytoplasm is basically the substance that fills the cell. It is usually a jelly-like fluid that is about 80% water, and usually it is clear in color. Cytoplasm is actually a little bit thicker than water.
