Question

Difference between invertebrates and non chordates

Answer 1

The invertebrates are the organisms which lack the backbone, but invertebrates have the unprotected notochord which is available in the lower animals.

When it comes to starfish, insects, and others, they are the examples of invertebrates.

The non chordates are organisms that are with no chordate.

There are many lower species.

It ranges from amoebas to snails, earthworms, and sponges.

Answer 2

Answer:

• Invertebrates:

1. Animals classified as invertebrates lack the notochord-derived vertebral column and do not develop one. With the exception of the subphylum Vertebrata, these encompass all animals.
2. All invertebrates lack a spinal cord and a vertebral column; instead, the majority of them are covered in an exoskeleton.
3. These are often little and don't get very big.
4. own no lungs since they breathe through their skin.
5. Invertebrates are heterotrophic because they can't make their own nourishment.
6. Fission is the process of reproduction.

• Non-Chordates:

1. Animals without a notochord, an elastic rod-like structure that supports the body, are known as non-chordates. A tiny group of marine animals that resemble worms and are organized at the organ-system level make up this phylum.
2. They are animals that are cylindric, triploblastic, coelomate, or pseudocoelomate.
3. These creatures breathe through their gills, trachea, or body surface.
4. Most of the time, members cannot be separated based on gender.
5. Both sexual and asexual reproductive methods are available.
6. Although certain animals also experience internal fertilization, fertilization is external in nature.
7. Non-chordates typically have an open circulatory system in their bodies.
