BANK 2026 COMPLETE SOLUTIONS
◉ protist. Answer: protozoa
algae
water molds
plankton: photosynthetic
zooplankton= motile and non-photosynthetic
◉ Unicellular eukaryotic organisms. Answer: Giardia lamblia (diarrheal
-Beaver fever), Trichomonas (trichomoniasis), Plasmodium falciparum
(malaria) b) Examples -Plankton -zooplankton vs phytoplankton
◉ Parasitic Helminths. Answer: Examples -Flukes, tapeworms
◉ fungus. Answer: Examples -Aspergillus, Candida albicans,
Histoplasma capsulatum
◉ Algae. Answer: Photosynthetic, single or multicellulara)Examples -
Dinoflagellates, diatoms
◉ lichen. Answer: a simple slow-growing plant that typically forms a
low crusty, leaflike, or branching growth on rocks, walls, and trees
,◉ malaria. Answer: is a disease caused by Plasmodium falciparum
transmitted to humans by mosquitos
◉ Unicellular Eukaryotic Parasites. Answer: are nonphotosynthetic,
motile organisms that are always unicellular
◉ protists life cycle. Answer: Free-living or parasitic (life cycle in host)
Trophozoites (feeding and growth stage) vs cyst(inactive form with
protective wall, forms via encystment)
◉ protists reproduction. Answer: Asexual: Binary fission (identical copy
of cell), budding(a portion of the cell breaks off and forms a new cell),
schizogony(nucleus divides many times in one cell) forming
merozoiteswhich are stored in schizonts
Sexual: Production of haploid gametes that fuse (syngamy) or joining to
exchange of DNA (conjugation)
◉ protists morphology. Answer: Plasmalemma-Plasma
membraneuOptional: Pellicle, ectoplasm/endoplasm
◉ protists feeding. Answer: Heterotrophic, some are saprozoic(absorbs
simple organic molecules)
, ◉ protists locomotion. Answer: Flagella, cilia, or pseudopodia
◉ Giardia lamblia. Answer: >causes beaver fever
In the United States, Giardiais the most common human intestinal
parasite, causes severe diarrhea
◉ Trophozoite. Answer: Active feeding and growth stage
◉ cyst. Answer: Cell forms a protective wall for protection
◉ Syngamy. Answer: sexual reproduction-Fusion of haploid gametes
◉ conjugation. Answer: Exchange of genetic material between two
different mating types
◉ Binary fission. Answer: Asexual -Formation of identical copies of
each cell
◉ budding. Answer: asexual Part of a mature cell breaks off and
becomes a new cell
