The Correct Option is B

Solution and Explanation

Interstitial cells are reserve cells which can differentiate into any type of cells. Nematocytes are stinging cells used for offence and defence. Gastrodermal cells line the gastrodermis and intracellular digestion takes place inside these cells. All these cells are found in cnidarians. Choanocytes are found in sponges; they are specialised flagellated cells that line spongocoel and canals.

Animal Kingdom

Animals are eukaryotic, multicellular species that belong to the Kingdom Animalia. Every animal has a distinct characteristic. They get energy either by feeding on plants or on other animals. There are millions of species that have been recognized, few shares similar characteristics while others vary drastically.

Kingdom Animalia comprises all animals. In the midst of the five kingdoms, the largest kingdom is the animal kingdom. Animals are multicellular eukaryotes. Though, like plants, they do not possess chlorophyll or a cell wall. Therefore, members of the animal kingdom indicate a heterotrophic mode of nutrition. Kingdom Animalia is further classified into ten different subphyla based on their body designs or differentiations.

The different phyla of the Kingdom Animalia are as follows:

  1. Porifera
  2. Coelenterata (Cnidaria)
  3. Platyhelminthes
  4. Nematoda
  5. Annelida
  6. Arthropoda
  7. Mollusca
  8. Echinodermata
  9. Hemichordata
  10. Chordata
