Chapter 28, Problem 3TY
Summary Introduction
Introduction: It is believed that protist was the first eukaryotic organism that ever existed in nature. They are found in a variety of habitats such as the ocean, hot springs, polar regions and so on. However, it has been observed that protist generally prefer to live in a moist environment. Protists are studied under the kingdom named as “Protista”.
