Chapter 23, Problem 7RQ
Summary Introduction
To determine: The filter-feeding apparatus of sea squirts along with similarity and differences between the mode of feeding between these two groups and amphioxus.
Introduction: The cyclostomes or the lampreys modify and evolve with passing time, to form modern fishes with the complete development of jaws. The cephalochordates are advanced than the urochordates and evolve into jawless fishes called the cyclostomes.

Find illustrations of the excretory and digestive system of Phylum Platyhelminthes, Phylum Annelida and Phylum Chaetognatha. Explain how each differ from each other.
Both sea squirts (urochordates) and lancelets (cephalochordates) are filter-feeding organisms. Describe the filter-feeding apparatus of a sea squirt and explain in what ways its mode of feeding is similar to, and different from, that of amphioxus
In Hydrozoans such as the Obelia pictured above, what do gastrozooids and
gonozooids have in common, and what are their respective functions?
They are both medusae; gastrozooids produce polyps via budding, and gonozooids filter
particles from the water to feed
They are both polyps: gastrozooids filter particles from the water to feed, and gonozooids
produce reproductive medusac via budding
They are both medusae: gastrozooids filter particles from the water to feed, and gonozooids
produce polyps asexually via budding
They are both polyps; gastrozooids filter particles from the water to feed, and gonozooids
produce additional polyps via asexual budding
