Centriole - Present in all plants and animals

Vedclass · Answer

(C) The correct answer is $C$. Centrioles are cylindrical structures composed of microtubule triplets made of tubulin protein. They are typically found in animal cells and some lower plant cells (like certain algae and bryophytes),but they are absent in the cells of higher plants (angiosperms and gymnosperms). Therefore,the statement that centrioles are present in all plants and animals is incorrect. Ribosomes are composed of $rRNA$ and proteins. Ribozymes are $RNA$ molecules that possess catalytic activity,thus acting as enzymes.
