Arthropod Characteristics 1

Front

What is the cephalothorax in arthropods?

Back

The cephalothorax is a fused body segment that combines the head and thorax, found in some arthropods like crustaceans and arachnids.

Front

What is an exoskeleton?

Back

An exoskeleton is a hard outer structure that provides support and protection to arthropods, but it cannot grow and must be molted.

Front

What does it mean for an organism to be segmented?

Back

Being segmented means that the body is divided into distinct sections, allowing for more complex movements and flexibility.

Front

What percentage of arthropods are insects?

Back

Most arthropods, approximately 75%, are classified as insects.

Front

What are the main characteristics of arthropods?

Back

Arthropods have an exoskeleton, segmented bodies, jointed appendages, and a body divided into regions (head, thorax, abdomen).

Front

How do arthropods grow?

Back

Arthropods grow by molting, shedding their exoskeleton to allow for growth, as their exoskeleton cannot expand.

Front

What are jointed appendages?

Back

Jointed appendages are limbs or body parts that have joints, allowing for a wide range of movement, characteristic of arthropods.

Front

What is the difference between arachnids and insects?

Back

Arachnids have eight legs and two body segments (cephalothorax and abdomen), while insects have six legs and three body segments (head, thorax, abdomen).

Front

What role do arthropods play in ecosystems?

Back

Arthropods play crucial roles in ecosystems as pollinators, decomposers, and as a food source for other animals.

Front

What is molting in arthropods?

Back

Molting is the process by which arthropods shed their old exoskeleton to grow a new, larger one.
