The following cell structures can also be found in a typical animal eukaryotic cell: 1  Centrioles - help to organize the assembly of microtubules.â. 2  Chromosomes - house cellular DNA.â. 3  Cilia and Flagella - aid in cellular locomotion.â. 4  Cell Membrane - protects the integrity of the interior of the cell.â.
Earthworms can be found at just about every corner of the earth. They live in trees, in bark, and under rocks as well as along rivers and near springs, and ponds.orms feed off of leaves and dead grass which contain organisms that provide a healthy diet of bacteria, algae, and fungi to the worm. Worms feast on dirt as well, especially if they live deeper inside the earth. Worms also eat plants, fruits, and vegetables. Believe it or not, worms do have mouths.
Species in this phylum are found in all parts of the world. Some live in water, and some live on land. Burrowing annelids, like the earthworm, play an important role in helping organic matter decompose. Earthworms eat dead plants and animals.here are about 15,000 species in this phylum. The phylum includes earthworms, leeches, and marine worms known as polychaetes. Species in this phylum have metameric bodies. Metameric bodies are divided into segments called annuli. The annuli are covered in tiny hairs called setae. Setae help the worms move.
