What is the organisms basic body plan?

Answer 1

Arthropods have all of these characteristics:

• The body is divided into segments.
• Paired and jointed appendages (legs, antennae, claws, and external mouth parts)
• Exoskeleton (hard outer covering made of chitin and no internal bones). Periodically, the rigid exoskeleton is shed in a process called moulting.
• Bilateral symmetry (each side is a mirror image of the other side).
• Specialised mouth parts
• Compound eyes (like a fly)
• The circulatory system an open one, the only blood vessel usually being a tubular structure dorsal to the alimentary canal with lateral openings in the abdominal region.
• The nerves run along the lower part of the body below the digestive system - all except the brain.
• Respiration by means of gills, or tracheae and spiracles.

Answer 2

The basic body plan of an organism refers to its overall structure and organization of body parts, such as symmetry, number of body segments, and overall shape. It typically includes features like a head, trunk, and appendages, as well as internal organs arranged in a specific way. This body plan provides a blueprint for the organism's form and function.

Answer 3

The basic structure of all insects includes the head, abdomen and the thorax. The anatomy of insects may vary slightly but most of them are similar.

Answer 4

Arthropods have a segmented body, a tough exoskeleton, and jointed appendages.

Answer 5

Most but not all have a symmetrical body plan.
