Question

differentiate between endoskeleton anf exoskeleton ( five points of difference)

Answer 1

Exoskeleton:

1. Hard part that lies outside of the body is called exoskeleton.

2. Develops from ectoderm.

3. Mostly non-living e.g. scales, hair, horns, feathers.

4. The exoskeleton covers the muscles and soft tissue of the animal, providing better leverage for muscular movement.

5. This molting process takes place various times over the lifetime of the animal.

Endoskeleton:

1. Hard part that lies inside of the body is called endoskeleton.

2. Develops from endoderm.

3.They are less protective than exoskeletons

4. They are living, e.g. Bones, cartilages.

5. Another advantage of endoskeletons is that they grow as the organism grows in size.
