| Term | Definition |
|---|
| Paraphyletic | are protists paraphyletic or monophyletic |
| Primary producers | species that produce chemical energy |
| protists | many of the species at the base of food chains in aquatic environments are __ |
| global carbon cycle | movement of carbon atoms from CO2 in atmosphere to organisms in soil or ocean and back to atmosphere |
| feeding groove, distinctive mitochondria, sac-like support structures, two hairy flagella, no cell walls, extends a slender portion of cell for movement, chloroplast with double membrance, reproductive cells with singular flagellum at base, no cell walls, extends a wide lobe for cell movement | distinguishing morphological features for Protists in order from past to present |
| unikonta, chromalveolata | two divisions of 8 types of lineages of eukaryotes |
| Yes | Do the protists range in size from bacteria single cells to giant kelp? |
| single, nucleus, no cell wall, flagellum | what was the first eukaryote organism (single or multicelled) (nucleus or none) (cell wall or none) (flagellum or none) |
| plasma | The infolding hypothesis states that the nuclear envelope originates from the infoldings of the ______ |
| endosymbiosis theory | What theory proposes that the mitochondria originated when a bacterial cell took residence inside a eukaryote 2 bya |
| symbiosis | term for when an individual of two different species live in physical contact |
| endosymbiosis | term for when an organism of one species lives INSIDE the other |
| support for endosymbiosis | 1. mitochondria are the same size of bacterium and replicate by fission, have their own genomes, ribosomes in mitochondria are similiar to those in bacteria, can't be made in a cell that lacks them |
| a proteobacteria | are the mitochondrial gene sequences closer to the a proteobacteria or nuclear DNA of eukaryotes? |
| multicellularity | what was a key morphological innovation that occured in lineages of protists having to do with cellularity? |
| multicellularity | what is a synapomorphy shared by brown alge and all of plasmodial and cellular slime molds and some red algae |
| engulfing, absorbing, photosynthesis | what are the three ways that a protist feeds? |
| lack | the engulfing process of protist feeding is possible in protists that ____ a cell wall |
| pseudopodia | "false feet" fingerlike projections allow these protists to swallow prey |
| decomposer | organism that feeds on dead or organic matter (detritus) |
| parasite | absorptive species that damages the host |
| cyanobacterium | the endosmbiosis theory contends that the organelle where photosynthesis takes place originates when a protist engulfed a ______ type of bacterium, they exchange O2 and glucose for protection and access to light |
| amoeboid motion | term for the sliding movement observed in some protists |
| ATP | what does the amoeboid motion of some protists require (energy related) |
| YES | is sexual reproduction viewed as an adaptation to fight disease? |
| fertilization | fusion of two gametes to form a diploid zygote |
| alternation of generations | when multicellular protists have one phace of life cycle based on haploid form and another on diploid form |
| gametophyte | haploid form, mitosis |
| sporophyte | diploid form, meiosis |
