Chapter 26.4, Problem 2C
Summary Introduction
To explain: The reason some biologists think that apicomplexans descended from dinoflagellates.
Introduction: Chromalveolates refer to a super-group of protists that originated due to secondary endosymbiosis. In this endosymbiosis, an ancestral cell engulfed a red alga giving rise to chromalveolates. Chromalveolates are further divided into two main groups, one of which is alveolates.

- Which class of Cnidarian is described below: This class includes the corals and the sea anemones. Individual animals are cylindrical in shape and are attached directly to a substrate in the polyp body form. Question 18 options: a) Class Hydrozoa b) Class Scyphozoa c) Class Cubozoa d) Class Anthozoaarrow_forwardDifferentiate the functions of the macro-and micronuclei of ciliates. What is the advantage of having dimorphic nuclei as compared to the monomorphic nucleus of other protozoans? Apicomplexans are widespread and common parasites of worms, echinoderms, insects, and vertebrates (including humans). What characteristics do these protozoans have that make them highly infective (efficient as parasites)? How can foram fossils provide clues about past cold and warm periods, and global temperature change? What characteristics separate Euglenozoans from Chlorophytes (i.e., Volvox, green algae)?arrow_forwardSome literature lists the 4 groups of protozoans as: 1) Flagellates 2) Amoebas 3) Ciliates 4) Sporozoans But other sources list the 4 groups as: 1) Flagellates 2) Amoebas 3) Heliozoans 4) Ciliates Compare and contrast heliozoans vs. sporozoans.
