What type of symmetrically organized organisms are included in the arthropod group?

Arthropods are a diverse group of invertebrates characterized by jointed bodies and appendages, a segmented body plan, and an exoskeleton made of chitin. The group includes creatures such as insects (like beetles, ants, and butterflies) and arachnids (such as spiders, scorpions, and ticks). Both insects and arachnids show bilateral symmetry, which means their body can be divided into mirror-image halves. This structural organization is essential for developing complex body plans and highly specialized appendages.

Insects typically have three pairs of legs and a body divided into three segments: the head, thorax, and abdomen. Arachnids, on the other hand, have four pairs of legs and a body divided into two segments: the cephalothorax and abdomen. Their symmetrical organization has allowed them to evolve various adaptations for survival in numerous environments.

The other options do not relate to the arthropod group. Fungi and bacteria are entirely different kingdoms of life, and plants and algae belong to the plant kingdom, which has a different structure and lifecycle. Sponges and corals are part of the animal kingdom but belong to entirely different phyla (Porifera and Cnidaria, respectively
