Basal bodies and centrioles share the same internal structure - nine sets of microtubule triplets arranged in a cylindrical form. However, they are found in different locations.

Match each structure to its location.

Structure

Basal bodies
Centrioles

Location

At the bases of cilia and flagella in all cells
Near the nucleus in animal cells only

Correct Answer

(1) Basal bodies,At the bases of cilia and flagella in all cells
(2) Centrioles,Near the nucleus in animal cells only

Explanation

Although basal bodies and centrioles are structurally identical - both composed of nine sets of microtubule triplets - they differ in location:

  • Basal bodies are found at the bases of cilia and flagella in all cells that have these structures
  • Centrioles are found near the nucleus and are present only in animal cells, generally occurring in pairs
