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.
Worms live in almost all parts of the world including marine, freshwater, and terrestrial habitats. Some worms living in the ground help to condition the soil (e.g., annelids, aschelminths). Many thrive as parasites of plants (e.g., aschelminths) and animals, including humans (e.g., platyhelminths, aschelminths).Several other worms may be free-living, or non parasitic. There are worms that live in freshwater, seawater, and even on the seashore.orms are hermaphrodites (both sexes in one animal) but can cross fertilize. Other invertebrate groups may be called worms, especially colloquially. In particular, many unrelated insect larvae are called worms, such as the railroad worm, woodworm, glowworm, bloodworm, inchworm, mealworm, silkworm, and wooly bear worm.
