what is it called when a diploid, multi-cellular, spore producing organism (sporophyte) alternates with a haploid, multicellular. gamete-producing organism (gametophyte)
Alternation of generation
-
what is a haploid organism that produces haploid spores
sporophyte
-
same form (gameteophyte and sporophyte) look alike
isomorphic
-
gameteophyte and sporophyte look different
heteromorphic
-
sexual process involving exchange of genetic material without reproduction; carried out by paramecium
conjugation
-
what organism has 2 different types of nuclei
paramecium
-
which nuclei controls everything that happens in a cell?
macronucleus
-
which nuclei can be in multiples and be involved in conjugation
Micronuclei
-
5 cilliates that protists are divided into which are related to each other
chromalveolates, plantae, excavates, rhizaria, unikonts
-
what is different about each group of cilliates?
they each have different rRNA
-
what has membrane bound sacs (alveolates) located just underneath the plasma membrane?
alveolates
-
what are the characteristics of a dinoflagellate?
unicellular, biflagellate, mostly marine and photosynthetic, alveoli often form armored plates made of cellulose, bioluminescent, some are endosymbiotic with coral and giant arms.
-

what are unicellular flagellates?
excavates
-
name 3 types of excavates

-
what has multiple flagella, 2 nuclei, reduced mitochondria, and are parasitic
diplomonads
-
what is an example of diplomonads that contaminates water and causes travelers diarrhea
Giardia Lambia
-
what have multiple flagella, reduced mitochondria, symbiotic relationships with incects and animals, and undulating membrane (some)
parabasalids
-
what is an example of a parabasalid that is an STD?
