Are bats blind or are they all on radar

Sponges have...a. a coelom
b.tentacles
c. specialized cells
d. bilateral symmetry

Answers

Answer:

c. specialised cells

Explanation:

Sponges are invertebrates that belong to phylum Porifera. Most of them live in marine environment. They do not have true tissues or organs but specialised cells that perform specific functions for example porocytes, amoebocytes, pinacocytes and choanocytes. Porocytes control the water amount entering inside the sponge pores and choanocytes control the water movement inside the sponge body.

Sponges consume food via phagocytosis. They reproduce both asexually and sexually. They are sessile i.e. immobile.

Final answer:

Sponges have specialized cells that perform specific functions like filtering food and excreting waste. They do not have a coelom, tentacles, or bilateral symmetry.

Explanation:

Sponges have specialized cells. These cells are responsible for the various functions of sponges, such as filtering their food and excreting waste. Some examples of specialized cells in sponges are collar cells, which line the inside of the sponge and generate water flow, and amoebocytes, which transport nutrients throughout the sponge. Sponges do not have a coelom, tentacles, or bilateral symmetry.
