Textbook Question
Chapter 11, Problem 1RQ
How does a unicellular eukaryote acquire considerable structural complexity within the constraints of a single cell?
Expert Solution & Answer
Summary Introduction
To explain: The reason how unicellular eukaryotes obtain a considerable structural complexity within the constraints of a single cell.
Introduction: The unicellular eukaryotes mainly belong to algae, fungi, and protozoa. The unicellular eukaryotes are made up of only one cell that carries out all the functions required by the organism. Some common examples are Euglena, Protozoa, Paramecia, and Physarum.
Explanation of Solution
The unicellular eukaryotes are single-celled micro-organisms with a defined nucleus, mitochondria, and other organelles. The organelles of unicellular eukaryotes are responsible for a variety of cellular functions. It includes producing energy, obtaining nutrients, and making proteins. Therefore, the structural complexity within a single cell is the result of the organelles that are present. Thus, the unicellular eukaryotes have more structural complexity within the constraints of a single cell.
