CELL ORGANELLES

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What organelle does all THREE of the following functions:a) Is part of the cytoskeleton and gives shape to the cell; b) Is a “monorail” on which other molecules travel around the cell; and c) Forms spindle extensions and attaches to chromosomes when it is time for the cell to divide.
A
Endoplasmic reticulum
B
Golgi Apparatus
C
Microfilaments
D
Microtubules
Explanation: 

Detailed explanation-1: -Microtubules, major constituents of the cytoskeleton, are involved both in these intracellular transport processes and in the spatial organization of cytoplasmic organelles. Accumulating evidence suggests that various classes of membranous organelles interact with microtubules.

Detailed explanation-2: -Among the more important cell organelles are the nuclei, which store genetic information; mitochondria, which produce chemical energy; and ribosomes, which assemble proteins.

Detailed explanation-3: -The fundamental functions of the cytoskeleton are involved in modulating the shape of the cell, providing mechanical strength and integrity, enabling the movement of cells and facilitating the intracellular transport of supramolecular structures, vesicles and even organelles.

Detailed explanation-4: -Microtubules are complexes of the protein, tubulin. They are the largest diameter of the cytoskeleton members and serve as “monorails” along which organelles can move about (see kinesin and dynein).
