Q. 27 - Biology

Question

Both hydrostatic and exoskeletons can protect internal organs from harm. Contrast the ways the skeletons perform these functions. 

Step-by-Step Solution

Answer

• Internal organs are shielded from damage by hydrostatic skeletons, which absorb shock from the outside environment. 
• However, these skeletons are not protective against outside threats. 
• Organs are protected from environmental damage by exoskeletons, which are stiff structures. 
• The animal will need to cushion its internal organs in different ways because they are rigid and offer little stress absorption.

Step 1 : Introduction

The hydrostatic skeleton is fluid-based, and it will form an internal fluid-based cushion around the organs, so fluid cushion, whereas the exoskeleton will form a hard outer layer, so their abilities will differ. The hydrostatic skeleton is extremely effective at shock absorption. 

Step : 2 Hydrostatic skeleton

• A fluid-filled compartment maintained under hydrostatic pressure makes up a hydrostatic skeleton.  
• A hydrostatic skeleton is produced by a fluid-filled area of the body called the coelom. 
• The animal can move in a more flexible way because to its hydrostatic skeleton because it uses relatively little muscle mass to move.

Step : 3 Exoskeleton

• The insect is shielded from desiccation by the exoskeleton, which also acts as a water-tight barrier. 
• Exoskeleton, a hard or flexible covering that supports and shields an animal's soft tissues. 
• The exoskeleton's role as a barrier keeping pathogens from entering the animal's inside is a crucial one.
