Protist Cell Structure and Metabolic Diversity
This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.
State
Protist cells range from microscopic to enormous and multinucleate, and use every metabolic strategy: photoautotrophy, heterotrophy, and mixotrophy, switching as conditions change.
Show
Euglena photosynthesizes in light but absorbs nutrients in darkness, a mixotroph switching strategy as its environment changes.
Watch for
A single protist species can shift metabolic strategy within its lifetime — metabolism is not always fixed by species alone.
