Some of the ways a roundworm is different from a flatworm include:

Body Shape

  • Flatworms have flat, ribbon shaped bodies, while roundworms are round (but not segmented) and taper towards the end. Both are bilaterally symmetrical.
Reproduction
  • Roundworms are sexed, with two different genders, while flatworms may either be sexed, hermaphroditic, or use asexual reproduction.
Digestive System
  • Flatworms have a one-way digestive tract. Waste is taken in and expelled through the same hole. Roundworms have a two-way tract, with a mouth and anus.

Flatworms are the first organisms to exhibit three distinct cell layers. The ectoderm, mesoderm , and endoderm.

They are classified as acoleomates meaning they have no true body cavity (coelom).

They contain bilateral symmetry. These organisms exhibit cephalization. Many of there sense organs are grouped at the anterior end of the organism. This affords them directional movement. Usually the first part of an organism that enters a new environment is the head.

They contain rudimentary organ systems such as: a ladder-like nervous system with a small brain and in some cases photosensitive eye spots. A network of flame cells used to sweep nitrogenous waste out of the body. A primitive digestive system consisting of a mouth, pharynx and branched gastrovascular cavity.

Phylum Nematoda : (Roundworms) Ascaris, pin worms, hookworms, and Trichina

They contain three cell layers.

They possess bilateral symmetry.

They are pseudocoelomates. Their body cavity is partially lined with mesoderm so they call it a false body cavity.

They possess a one way digestive system. Mouth, intestine and anus.

They contain separate sexes. The female being the larger of the pair. Females are capable of producing 100 of thousands of eggs per day. The male usually dies after copulation.

They have a circular brain and several longitudinal nerve cords. The nitrogenous waste is collected by two lateral canals and emptied from the body through an excretory pore located in the head area.

They contain longitudinal muscles only. This makes it difficult for the worm to move in a coherent manner.

Their body is covered with a tough cuticle. This prevents the parasitic worms from being digested and the free living worms from drying out.

What is the human parasitic roundworm called?

Tapeworm.. I think. To the person who answered tapeworm, it is definitely not the tapeworm, as the former is a flatworm and not a roundworm. The most common roundworm that infects humans is Ascaris lumbricoides. Other roundworms that are also highly distributed include Trichuris trichiura, and the hookworms (Ancylostoma duodenale, and Necator Americanus).

Is a hookworm a roundworm or a flatworm?

Tape worms are not round worms. A tape worm is a flat worm. Both are intestinal parasites and feed off the nutrients that are provided by the host. A tapeworm is segmented and the segments break off and look like little grains of rice. A round worm is long and round. In large quantities they resemble spaghetti.


How does mitosis differ between the onion root and the roundworm?

The only difference between vegetal (onion) cells and animal (roundworm) is not quite in mitosis, but in citokinese (not a mitosis phase since mitosis refers to nucleus division). Vegetal cells have a thick wall rounding the cell which needs different means to split than the membrane in animal cells
