Q. What is the storage structure in a cell?
A vacuole is the storage area of the cell. Vacuoles store water, food, and waste. The endoplasmic reticulum (ER) is a series of tunnels throughout the cytoplasm. They transport proteins from one part of the cell to another.
Q. What are the 3 forms of ER?
Endoplasmic reticulum can exist in three forms (Fig. 8.31) — cisternae, vesicles and tubules.
Q. Are proteins synthesized in the smooth ER?
sER is a membrane-bound network of tubules (see Figs. sER is not involved in protein synthesis. Its main function is the synthesis of lipids, steroids, and carbohydrates, as well as the metabolism of exogenous substances, such as drugs or toxins.
Q. What are the two types of ERS?
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.
Q. What is the difference between the two types of ER?
The difference lies between the two is that the Smooth Endoplasmic Reticulum is not bounded by the ribosomes and is known for storing the lipids and proteins. Meanwhile, the Rough Endoplasmic Reticulum is bounded by the ribosomes and store proteins. ER is of two type smooth and rough.
Q. What moves proteins in a cell?
The Endoplasmic Reticulum or ER is an extensive system of internal membranes that move proteins and other substances through the cell. The part of the ER with attached ribosomes is called the rough ER. The ER moves proteins and other substances within eukaryotic cells.
Q. Which organelle is most like a skin?
Mitochondria
Q. What body part is like the endoplasmic reticulum?
The smooth and rough endoplasmic reticulum are a network of passageways that carries material from one side of the cell to the other. It is found in both plant and animal cells. The equivalent to it in the human body is the throat and/or the intestines.
