Final answer:
Colonial sea squirts have two types of polyps: gastrozooids and gonozooids. Gastrozooids capture prey and feed, while gonozooids produce asexual buds and sexual medusae. The medusae are either male or female and have separate testes or ovaries for gamete production.
Step-by-step explanation:
Colonial sea squirts have two types of polyps: gastrozooids and gonozooids. The gastrozooids are adapted for capturing prey and feeding, while the gonozooids are responsible for asexual budding and the production of sexual medusae. The medusae are either male or female and produce sperm or egg cells through meiosis. The gamete-producing cells do not arise within the gonads, as they do in other organisms.
