Question
Chapter 28.1, Problem 3CC
Summary Introduction
To determine: The numbers of distinct genomes contained within the cell of a chlorachniophyte. Refer to Fig. 28.3 “Diversity of plastids produced by endosymbiosis”, in the textbook.
Concept introduction: Chlorachniophyte are photosynthetic algae that can also feed on smaller protists and bacteria. They are the inhabitants of tropical oceans. The chloroplast of this alga is derived from the endosymbiotic relation of a eukaryotic alga.
Pictorial representation:
The diversity of plastids produced by endosymbiosis is represented in the Fig.28.3.
