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.
Habitat and Ecology: These worms live in muddy sediments, especially in shallow water along the edges of marshes and ponds throughout the United States, and many other parts of the world. Body and support: Mudworms usually have 150-250 body segments. They have no skeleton, but the fluid inside them gives them support and form.
