Question

Microtubules are the constituents of:

• A. Cilia, Flagella and Peroxisomes
• B. Spindle fibres, centrioles and cilia
• C. Centrioles, spindle fibres and chromatin
• D. Centrosome, Nucleosome and Centrioles

Answer 1

The correct option is B Spindle fibres, centrioles and cilia

Microtubules are structures present in cilia, flagella, centrioles and spindle fibres.
A peroxisomes is a membrane-bound organelle, that are found in the cytoplasm of a cell. It is a microbody.
Chromatin consists of DNA and proteins, which condenses to form chromosomes. Nucleosome is the basic unit of chromatin.
Centrosome is an organelle that is main place where cell microtubules are organized, it helps in regulating cell division cycle.
