context: Porifers reproduce sexually or asexually, species that reproduce sexually release sperm cells into water and meet eggs (some are released into the water and some remain in the body of the "mother"). Fertilized eggs swim to find a place to stick, and grow into new individuals. The sponge can regenerate from the cut, if the part has the right cells. Whereas those who reproduce asexually use three methods, namely: Shoots, Gemula, and fragmentation.
