Biology reading for 2/23/15Pages 160-165CiliatesCiliates: large and varied group of protists named for their use of cilia to move and feedMost are predatorsThe two nuclei of ciliates: micronuclei and macronucleiConjugation: a sexual process in which two individuals exchange haploid micronuclei but do not reproduceCilia: hair-like structures that cover the surface of rhizariansRhizarians: one of the three subgroups of “SAR”. Many are amoebas characterized by threadlike pseudopopdiaPseudopodiaPseudopodia: Extensions that may bulge from almost anywhere on the cell surfaceRadiolariansRadiolarians: protists that have delicate, intricately symmetrical foramForaminiferans/forams: an aquatic protest that secretes a pseudopodia through pores in the shellTests: porous shells of foramsForams are found in both fresh and salt watersCercozoansCercozoans: large group of amoeboid and flagellated protists that feed using thread like pseudopodiaMost are heterotrophs. Many are parasiticRed algae and green algae are the closest relatives of land plantsArchaeplastida: Monophyletic group that includes red algae, green algae, and land plants. Descended from an ancient protest ancestor that engulfed a cyanobacteriumRed algaeRed algae: Photosynthetic protists that contains red pigment that masks the green chlorophyllMost red algae are multicellular and marineRed algae reproduce sexuallyGreen algaeGreen algae: contain green chloroplasts and have structure and pigment compositions like plantsTwo main groups of green algae: the charophytes and the clorophytesUnikonts include protists that are closely related to fungi and animalsUnikonta: extremely diverse super group of eukaryotes that includes animals, fungi, and some protistsThe two major clades of unikonts: ameobozoans and opisthokontsAmebozoansAmoebozaoan clade: includes many species of amoebas that have lobe- or tube- shaped pseudopodiaSlime moldsThe two main branches of slime molds: plasmodial and cellularQuizlet link:
