Question

Identify the components labelled A, B, C and D in the given section of cilia/flagella showing different parts. Choose the option which shows the correct labelling of parts.

• A. A – Plasma membrane, B – Interdoublet Bridge, C – Central microtubule, D – Radial spoke
• B. A – Plasma membrane, B – Arm, C – Central microtubule, D – Radial spoke
• C. A – Plasma membrane, B – Interdoublet Bridge, C – Hub, D – Radial spoke
• D. A – Plasma membrane, B – Interdoublet Bridge, C– Hub, D – Arm

Answer 1

The correct option is A A – Plasma membrane, B – Interdoublet Bridge, C – Central microtubule, D – Radial spoke

In the given figure of cilia/flagella, the marked part as A, B, C and D are respectively plasma membrane, interdoublet bridge, central microtubule and radial spoke.
