Heterotrophic protists Study guides, Revision notes & Summaries

1) What are the characteristics of Protists? -Eukaryotic -Some are Unicellular and others are multicellular -Nonmotile and motile species -Aquatic and terrestrial species -Autotrophic (photosynthetic) and heterotrophic 2) Paramecium protist -earlier protist to be described -Unicellular -Not usual to find in palm water -Non-photosynthetic -Aquatic -motile -faster than amoeba 3) Amoeba -Unicellular -Heterotrophic -motile -aquatic -used too be considered animals since they moved but NOT ANIMALS ...

Alginate - A material that makes up the cell wall of Brown Algae. Alternation of Generation - Alternation between sexual and asexual phase in the life cycle of an organism. Photoautotroph/Photosynthetic - An organism that produces its own food via a light source. Heterotrophic - Organisms that get food by consumption, not light. Mixotrophic - ...

Eukarya: 4 Supergroups Excavata, SAR clade, Archaeplastida, Unikonta protists are a diverse group of eukaryotes that span all four supergroups - protists are eukaryotes - protists are very diverse - eukaryotic cells have organelles and are more complex than prokaryotic cells - the organisms in most eukaryotic lineages are protists - most protists are unicellular but there are some colonial and multicellular species the protists - excavata - some members of this supergroup have an "excavated"...

"Biologists practice evidence-based decision making." This statement means that: Biologists start by stating a hypothesis and a null hypothesis, without making prior observations because that might lead to bias. Biologists select between a hypothesis and a null hypothesis based on careful thought without data Biologists select between a hypothesis and a null hypothesis based on experiemental or observational data Only careful experimentation allows biologists to select between a hypothes...

Not very many proteins in the eukaryotic cytoplasmic membrane. Where did they go? - Answer-They are still in the membrane and they are still busy, but most of the proteins went to the mitochondrial membrane in eukaryotes. Cellulose and Chitin - Answer-Use specific b-1,4-glycosidic bonds between sugars provides strength and rigidity. In algae Fungi - Cell Wall - Answer-You have a NAG in chitin for cell walls in fungi. The cell wall is all NAGs Cytoskeleton Function - Answer-Involved in intr...

absorptive heterotroph - An organism (usually a fungus) that obtains its food by secreting digestive enzymes into the environment to break down large food molecules, then absorbing the breakdown products. acidophile - able to live in extremely acidic environments adaptations - inherited aspects of an individual that allow it to outcompete other members of a population that lack the trait; evolve through natural selection Alfred Russel Wallace - came up with a mechanism for evolution simila...
