Eukaryotes Have nucleus and membrane bound organelles Most are
unicellular, some are multicellular or colonial Can be plant-like,
fungus-like, or animal- like Kingdom is considered to be obsolete
and will be split into newly designated kingdoms
Slide 3
EUGLENOPHYTA Uincellular, have chlorophyll a and chlorophyll b
Have flagella tht protrude from a gullet and an eyespot that helps
them respond to light (phototaxis) Live in fresh water that is rich
with organic material May exist as autotroph or heterotroph
Slide 4
Unicellular organisms that live in marine and freshwater. Have
photosynthetic pigments, two flagella and cell walls of cellulose.
Some produce toxins associated with red tides.
Slide 5
Includes the golden algae Most are unicellular, some
multicellular Have photosynthetic pigments, golden color Cells are
covered with tiny scales of silica or calcium carbonate
Slide 6
Green Algae Have photosynthetic pigments Most have flagella at
some phase of their lives. Store food as starch
Slide 7
Brown algae - Mostly multicellular Photosynthetic and have
chlorophyll a,b,c plus carotinoids. Asexual zoospores and gametes
have two flagella. Includes giant kelps
Slide 8
Red Algae Mostly multicellular marine seaweeds. Have
chlorophyll a and b and red pigment called phycobillin Found at
great depths Used in sushi
Slide 9
Diatoms Usually non-motile unicellular organisms Cell walls are
in two parts and are made of silica (look like petri dish)
Slide 10
Non-photosynthetic Heterotrophs
Slide 11
Unicellular protozoa Move by flagella Some live in guts of
termites Trichonympha Others are parasitic and cause disease, such
as African sleeping sickness, Trypansoma
Slide 12
Amoeba Performs phagocytosis by surrounding and engulfing food
using pseudopodia (false feet)
Slide 13
Unicellular protists Have calcareous shells with pores through
which cytoplasm extends
Slide 14
Unicellular protozoans Move about and feed using tiny hairs
called cilia. Best know is Paramecium, has two nuclei, and oral
groove, and contractile vacuoles
Slide 15
Non-motile parasitic spore-formers Lack flagella Amoeboid body
form Include Plasmodium, the malaria parasite In red blood
cells
Slide 16
Slime molds produce large multinucleated masses (plasmodium
different than malaria Plasmodium) Some have stalks that grow
upward and form spores Other times produce gametes which fuse and
produce a diploid zygote that forms the multinucleate mass Found in
moist soil, decaying leaves or logs in a damp forest.
