Final answer:
The statement about protists that is not true is 'C) Most protist cells have mitochondria and chloroplasts', as not all protists contain chloroplasts; they are specific to plant-like protists with photosynthetic capabilities.
Step-by-step explanation:
The statement about protists that is NOT true is: C) Most protist cells have mitochondria and chloroplasts. While it is true that most protists have mitochondria, they do not all have chloroplasts. Chloroplasts are found specifically in plant-like protists that can perform photosynthesis. Protists are diverse in how they obtain energy; some have mitochondria for respiration, while others may rely on photosynthesis if they possess chloroplasts, and still others may be parasites or obtain energy through absorption.Let's review the statements for accuracy based on what is known about protists:A) All protist cells have a nucleus - This is true, as protists are eukaryotic organisms which inherently have a nucleus.B) Protists can be parasites - This is also true; some protists are known to be parasitic.D) Protists prefer water-based environments - Many protists do indeed prefer aquatic or moist environments, though some can also be found in soil or other habitats.
