Question

` Write a note on the electron microscopic strueture of a cilium or a flagellum.`​

Answer 1

Answer:

Flagella and cilia consist of 9 fused pairs of protein microtubules with side arms of the motor molecule dynein that originate from a centriole. These form a ring around an inner central pair of microtubules that arise from a plate near the cell surface. The arrangement of microtubules is known as a 2X9+2 arrangement.
