Question

Name the organelle which shows the analogy written as under Transporting channels of the cell are

Answer 1

Hint: There are many cell organelles with different functions. Transporting channels form a connection between the cell membrane to the nuclear membrane. Proteins pass through them before reaching their final destination. Proteins bud off to form vesicles which travel along the cortex of the cell to reach their destination.

complete answer:
-Endoplasmic reticulum is concerned with the transport of various substances across the cell.
-It plays a major role in the synthesis of proteins and lipids.
-Endoplasmic reticulum is of 2 types. Rough endoplasmic reticulum and smooth endoplasmic reticulum.
-Rough endoplasmic reticulum has the presence of proteins on its surface. So it can synthesize proteins.
-In the synthesis of lipids Smooth endoplasmic reticulum is involved.
-Endoplasmic reticulum is a continuous membrane system with flattened sacs found in the cytoplasm.
-It can secrete as well as package many cell products.
-It is not present in prokaryotes.
-It plays the role of a cell regulator. In other words, they can act as an internal delivery system within the cell.
-Its secretions move to Golgi bodies for additional processing.

Additional information:
-There are many other membrane-bound cell organelles.
-Golgi body packs products to form membrane-bound vesicle-like structures. Later these vesicles move to the right destination.
-Lysosomes act as suicidal bags. They possess many hydrolytic enzymes that hydrolyze at acidic pH.
-Vacuoles are meant for storage. They are prominent in plant cells. They play a major role in maintaining the osmotic concentration of the cell.

Note: Plastids are found in plant cells only. These can be aleuroplasts, elaioplasts, chloroplasts. Centrosomes are found in animal cells only. They form spindle fibers. In the plant cells, microtubules form the same.
