- Heterotrophic cell digests a photosynthetic prokaryote to produce algae?
- each endosymbiotic process adds another layer of membrane
o 2 membranes 1 endosymbiotic event occurred
o pellicle pellicle bands, allows to change shape as it swims
o mixotroph photosynthesis AND ingest organic molecules
o Plates give its shape
o 2 flagella One flagella wraps around cell to spin it, the other
remains perpendicular to move forward/backward?
o Excellent fossils due to their frustules?
o 2 flagella one to move forward, and one to move backward
o Photosynthetic, but also ingest food by phagocytosis
o UV absorbing compounds protects from UV rays
- Brown Multicellular algae
o Holdfast Anchors cells
o Although they look like plants, they lack
