Answer: True
Protists are a diverse group of eukaryotic microorganisms, which means they possess a defined nucleus and organelles. Unlike prokaryotic organisms, such as bacteria, which lack a nucleus, protists have their genetic material enclosed within a nuclear membrane. Additionally, they contain various organelles, such as mitochondria and endoplasmic reticulum, which perform specific functions necessary for the cell’s survival and metabolism. This complex cellular structure allows protists to carry out various life processes, making them distinct and important in ecosystems.
