The exoskeleton provides protection, support, and prevents water loss in arthropods.

Front

How do arthropods grow?

Back

Arthropods grow through a process called molting, where they shed their exoskeleton to allow for growth.

Front

What is the significance of jointed appendages in arthropods?

Back

Jointed appendages allow for greater mobility and flexibility, enabling arthropods to perform various functions such as walking, swimming, and grasping.

Front

What is the respiratory system of most arthropods?

Back

Most arthropods breathe through structures called tracheae or gills, depending on whether they are terrestrial or aquatic.
