Answer:
The difference between the microfilaments, intermediate filaments, and microtubules are stated below.
Explanation:
- They are made up of two chains made up of monomeric globular proteins called actin. The chains are coiled around each other.
- They have a diameter of about 7 nanometre.
- They help in cellular movement.
- They form strands which are made up of fibrous proteins like keratin, vimentin, desmin.
- They have a diameter which ranges from 8 nanometre to 10 nanometre.
- They have structural function and are required to maintain the cell shape and organelle position.
- They are formed when the globular proteins, alpha-tubulin and beta-tubulin form dimer and undergo polymerisation.
- They have a diameter of about 25 nanometre.
- They form the structural components of flagella, cilia and centrioles. They prevent cell compression.
Answer;
-Electron microscopes can not view live cells because the method of preparation is lethal.
Explanation;
-The electron microscope is a type of microscope that uses a beam of electrons to create an image of the specimen. It is capable of much higher magnifications and has a greater resolving power than a light microscope, allowing it to see much smaller objects in finer detail.
-There are many different disadvantages to using a electron microscope for example they are extremely expensive which limits the availability to use them. Furthermore researchers are unable to observe the image in color, as electrons do not possess color, which may not allow the image to be understood easily.
-Additionally the use of the electron microscopes require a large space for example a whole room which may not be feasible.
