Assertion: Centrosomes and centrioles are related to each other.
Reason: Centrosome usually contains two cylindrical structures called centrioles.
(a) If both Assertion and Reason are correct and Reason is the correct explanation of Assertion.
(b) If both Assertion and Reason are correct, but Reason is not the correct explanation of Assertion.
(c) If Assertion is correct but Reason is incorrect.
(d) If both the Assertion and Reason are incorrect.
Answer is: (a)
Explanation:
The centrosome is the main place where cell microtubules get organized. Centrosome usually contains two cylindrical structure called centrioles. Centrioles are composed of grouping of microtubules arranged in 9 + 3 pattern. The pattern is so named because a ring of 9 microtubule "triplets" are arranged at right angles to one another. Centrioles, found in animal cells, help to organize the assembly of microtubules during cell division. Centrioles replicate during the interphase stage of mitosis and meiosis.
