Respuesta :
The correct option is (D) Sponges
The class of animals known as sponges, or Phylum Porifera, or "pore bearers," has over 5,000 different species.
Describe sponges.
- Sponge bodies are made up of a loose collection of cells encased in a gelatinous matrix, despite the fact that they are multicellular. Sponge bodies also have a very simple level of organization.
- Sponge cells come in a variety of types, including amoeboid cells called archeocytes that move around in the mesohyl and can differentiate into other types of cells that form parts of the skeleton (composed of collagen and/or spongin fibers), flagellated cells called choanocytes that line inner chambers and canals, and epithelial-like cells called pinacocytes that cover the exterior and non-flagellated interior.
- In Metridium, a ciliated groove known as the siphonoglyph stretches from the mouth down one side of the pharynx. Currents of water are brought into the sea anemone by the cilia in this groove.
