What can the endoplasmic reticulum be compared to? What is an analogy for endoplasmic reticulum? How is the endoplasmic reticulum like a school?

What is the main function of endoplasmic reticulum? What part of a school is like rough ER? What would a nucleolus be in a school? What does the ER do in a plant cell? What is rough endoplasmic reticulum in school? Why is RER Class 9 rough? Why RER membrane is rough in nature? What is difference between rough and smooth endoplasmic reticulum?

Why rough endoplasmic reticulum should be and is rough? What happens if rough ER is defective? What is the rough endoplasmic reticulum like in real life? In which cell would you find the most rough ER? What happens if cytoplasm is defective? What happens if a nucleus is defective? What would happen if nucleus is removed from the cell?

What does cytoplasm look like? Cells in your body that release oils also have more SER than most cells. It is able to store many ions in solution that the cell will need at a later time. It is easier to have them stored in a pack for easy use. For example, when you are running around and your muscle cells are active, they need calcium Ca ions.

The SR can release those ions immediately. When you are resting, they are able to store them for later use. Useful Reference Links. See the full list of biology topics at the site map!

Many of these products are made for and exported to other organelles. This is an electron microscope image showing part of the rough endoplasmic reticulum in a plant root cell from maize. The dark spots are ribosomes. There are two types of endoplasmic reticulum: rough endoplasmic reticulum rough ER and smooth endoplasmic reticulum smooth ER.

Both types are present in plant and animal cells. The two types of ER often appear as if separate, but they are sub-compartments of the same organelle. Cells specialising in the production of proteins will tend to have a larger amount of rough ER whilst cells producing lipids fats and steroid hormones will have a greater amount of smooth ER.

Part of the ER is contiguous with the nuclear envelope. The Golgi apparatus is also closely associated with the ER and recent observations suggest that parts of the two organelles, i. This is an extensive organelle composed of greatly convoluted but flattish sealed sacs, which are contiguous with the nuclear membrane.

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. This process is called translation. Certain cells of the pancreas and digestive tract produce a high volume of protein as enzymes. Many of the proteins are produced in quantity in the cells of the pancreas and the digestive tract and function as digestive enzymes.
