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.
What do they look like? Earthworms are smooth-skinned worms, with a body made of many small segments. If you look at the body you can see lines that mark the segments. Each segment has stiff little hairs that help the worm move, sometimes the hairs are hard to see. They have no skeleton, but do have lots of muscles. Earthworms don't have much coloration, so they usually look white, gray, pink, or reddish brown. Some earthworms have red blood, and you can see it through their skin. Their skin produces slimy mucus that helps them slide through the soil. Like most animals they have a front and back end, and their mouth and tiny brain are at the front.
