Organismal LabFUNGIFungi are diverse and widespread. Fungi exhibit diverse lifestyles as decomposers, parasites, and/or mutualists. Despite their diversity, fungi share key traits, most importantly the way in which they derive nutrition. Fungi are heterotrophs and absorb nutrients from outside of their body. Fungi use enzymes to break down a large variety of complex molecules into smaller organic compounds. The versatility of these enzymes contributes to fungi’s ecological success. The morphology of multicellular fungi enhances their ability to absorb nutrients. Fungi consist of mycelia, networks of branched hyphae adapted for absorption. 1.

INVERTEBRATESInvertebrates are “animals without backbones.” Almost 2 million identified species are invertebrates, accounting for more than 98 percent of the animal kingdom. They live in an incredibly diverse range of habitats both on land and in water. Among the more recognizable marine and coastal invertebrates are octopus, squid, lobster, crabs, clams, scallops, starfish, sea worms, corals and anemones. While invertebrates are remarkably diverse animals, there are two basic body plans. Those having radial symmetry (corals and anemones) are rounded bodies arranged around a central mouth. These animals typically spend their lives in one place (sessile) and wait for food to come to them. Those having bilateral symmetry are those with two halves that mirror each other, with a distinct front and back. Bilateral symmetry characterizes most invertebrates. They can have several pairs of eyes and other specialized organs that can smell, touch and taste. Crabs and squid are good examples of bilaterally symmetrical invertebrates.Sponges. Sponges are the simplest of multi-cellular animals. A sponge is a
