Question
Chapter 18, Problem 8WIO
Summary Introduction
To determine:
Why overwatering the plants make them more susceptible to infection by some kinds of heterotrophic protists.
Concept introduction:
Protists are simple eukaryotic cells that can be unicellular or multicellular. Protists often have cellular organelles and they demonstrate both animal and plant like characteristics. Protists can be heterotrophic or autotrophic. Heterotrophic protists cannot make their own food.
