What is the endoplasmic reticulum like in a school?

What is the endoplasmic reticulum like in a school?

The endoplasmic reticulum is like hallways in a school because they are passage ways for students and staff like the endoplasmic reticulum makes passages for proteins. The Golgi apparatus is like a school bus because a school bus transports kids to school like the Golgi apparatus ships proteins.

Do plant cells have rough ER?

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.

What do plant cells have instead of lysosomes?

Plant cells have plasmodesmata, a cell wall, a large central vacuole, chloroplasts, and plastids. Animal cells have lysosomes and centrosomes.

Why are lysosomes the most important?

A lysosome is a membrane-bound cell organelle that contains digestive enzymes. They break down excess or worn-out cell parts. They may be used to destroy invading viruses and bacteria. If the cell is damaged beyond repair, lysosomes can help it to self-destruct in a process called programmed cell death, or apoptosis.

What kind of enzymes are present in lysosomes?

Lysosomes are membrane-bound vesicles that contain digestive enzymes, such as glycosidases, proteases and sulfatases. Lysosomal enzymes are synthesized in the endoplasmic reticulum (ER), are transported to the Golgi apparatus, and are tagged for lysosomes by the addition of mannose-6-phosphate label.

What would happen to a cell if its lysosomes ruptured?

If lysosomes get ruptured within a cell all the acid hydrolytic enzymes will come out into the protoplasm, the cellular components will be digested in the same manner as during autophagy and autolysis and the cell will die.

What will happen to the cell if its lysosomes would burst because of lack of oxygen?

When a cell is deprived of oxygen, its lysosomes tend to burst and release their contents into the cell.
