Porocytes control the flow of water through pores in the sponge body.

Chapter 28, Problem 1VCQ, Figure 28.3 Which of the following statements is false? Choanocytes have flagella that propel water

Expert Solution & Answer

Summary Introduction

Introduction:

Generally, sponges do not show true tissue-layer organization and do not have a number of functional tissues, that made up of different cell types specialized for distinct functions such as pinacocytes Pinacocytes is epithelial-like cells and form the outermost body, called a pinacoderm, that serves a protective function similar to the epidermis. Pinacoderm scattered among all area of Ostia that allow entry of water into the body of the sponge.

Answer to Problem 1VCQ

Correct answer:

Correct answer is option (b), Pinacocytes can transform into any cell type.

Explanation of Solution

Explanation/justification for the correct answer:

Option (b) is given as Pinacocytes can transform into any cell type. Pinacoderm scattered among all area of ostia that allow entry of water into the body of the sponge. In some sponges, ostia are made up of porocytes, these single tube-shaped cells act as valves to regulate the flow of water into the spongocoel. It is a correct answer.

Explanation for the incorrect answer:

Option (a) is given as choanocytes have flagella that propel water through the body. Choanocytes line is the inner portions of spaces in the sponges that allow the flow of water. The water current is maintained through the presence of flagella so that food particles can be trapped and ingested via phagocytosis. It is a wrong answer.

Option (c) is given as lymphocytes secret collagen. Lophocytes is a specific type of cells in sponges that able to produce protein like collagen for maintenance of mesophyll. it is a wrong answer.

Option (d) is given as porocytes control the flow of the water through pores in the sponge. Porifera is a phylum that cover sponges that pore-bearers, in some sponges, porocytes make ostia like single tube-shaped cells that act as valves and help to regulate the flow of water into the spongocoel. it is a wrong answer.

Conclusion

Thus, Pinacocytes can transform into any cell type is a false statement.
