Explanation:

Sponges have both asexual and sexual reproduction. Asexual reproduction is budding (external or internal). In unfavorable conditions, gemmules form. Sponges are hermaphrodites but produce one type of sex - cell at a time. Sperm is released through the osculum, carried by currents, and enters another sponge through ostia. Choanocytes trap sperm, which fertilizes oocytes (eggs) to form zygotes that develop into larvae. Larvae swim with cilia and settle to become adults.
