The movement of water in leuconoid type of canal system is
Dermal ostia → Incurrent canals → Flagellated chambers → Apopyles → Excurrent canals → Larger channels → Oscula → Out
Dermal pores → Incurrent canals → Prosopyles → Radial canals → Internal ostia
(apopyles) → SpongocoeL → Osculum → Out
Water from exterior → Incurrent pores → Spongocoel → Osculum → Water out
Incurrent canals → Radial canals → Prosopyles → Dermal pores → Internal ostia
(apopyles) → SpongocoeL → Osculum → Out
Answers (1)
In the leuconoid canal system, water enters through dermal pores, then flows through incurrent canals, prosopyles (openings leading to radial canals), radial canals, internal ostia (apopyles), spongocoel (central cavity), and finally exits through the osculum. This system facilitates water circulation and filtration within the sponge.
Dermal pores → Incurrent canals → Prosopyles → Radial canals → Internal ostia
(apopyles) → SpongocoeL → Osculum → Out
Hence, the correct answer is option 2.
