Protists!!
Welcome Bienvenidos What is the difference between an autotroph and a heterotroph? Think of two examples of autotrophs and two examples of heterotrophs. What is the difference between single-celled and multicellular organisms? Give me three examples of single-celled organisms!
Inside of every drop of pond water… https://www.youtube.com/watch?v=0-6dzU4gOJo WOW!!!!
The mysterious lives of pond creatures!! Stand up if you see a creature you recognize! https://www.youtube.com/watch?v=tIMJWWpOrjw
Get their energy from eating other organisms Heterotroph Get their energy from eating other organisms Ex. Humans, animals Autotroph: Get their energy from the sun Ex. Plants, protists
Organisms made of many cells Ex. Humans, animals Single-celled Organisms made of 1 cell. Ex. Bacteria, protists Multi-cellular Organisms made of many cells Ex. Humans, animals
Asexual Reproduction: 1 parent to reproduce – dividing, replicating, etc. http://www.youtube.com/watch?v=DY9DNWcqxI4 https://www.youtube.com/watch?v=gEwzDydciWc Sexual Reproduction: 2 parents – combining egg and sperm.
PROTISTS are… SINGLE-CELLED!!
ALL PROTISTS are… EUKARYOTIC Which means they have a NUCLEUS!!!
Amoeba (Blob Shape Shifters) https://www.youtube.com/watch?v=7pR7TNzJ_pA Lives… Ponds, dead and decaying organisms Heterotroph Locomotion: use PSUEDOPODS (false feet) Reproduces…Asexual Reproduction
Amoeba Single-celled or multicellular? Prokaryotic or Eukaryotic? https://www.youtube.com/watch?v=7pR7TNzJ_pA Gets rid of waste with a Contractile Vacuole Single-celled or multicellular? Prokaryotic or Eukaryotic? Special Features? Shape-shifter!
Paramecium Lives… Ponds, freshwater Heterotroph http://www.youtube.com/watch?v=saLYHUs6cWk Lives… Ponds, freshwater Heterotroph Locomotion: Moves using CILIA – tiny hairs Reproduces asexual reproduction
Paramecium Single-celled or multicellular? Prokaryotic or Eukaryotic? Gets rid of waste with a Contractile Vacuole Single-celled or multicellular? Prokaryotic or Eukaryotic? Special Features? Two Nucleus’s The most complex!
Euglena Lives…Ponds, freshwater Autotroph AND heterotroph https://www.youtube.com/watch?v=jl0TzaWUQWk Lives…Ponds, freshwater Autotroph AND heterotroph Locomotion: Moves with flagella (tail) Reproduces…Asexual Reproduction
Euglena Single-celled or multicellular? Prokaryotic or Eukaryotic? https://www.youtube.com/watch?v=jl0TzaWUQWk Gets rid of waste with a Contractile Vacuole Single-celled or multicellular? Prokaryotic or Eukaryotic? Special Features? BOTH autotroph and heterotroph
Volvox Ponds, freshwater Autotroph http://www.youtube.com/watch?v=w8O4OolGcPg Ponds, freshwater Autotroph Locomotion: Moves with 2 flagella (tails) Reproduces: Asexual AND sexual Reproduction
Volvox Single-celled or multicellular? Prokaryotic or Eukaryotic? http://www.youtube.com/watch?v=w8O4OolGcPg DOES NOT NEED TO GET RID OF WASTE Single-celled or multicellular? Prokaryotic or Eukaryotic? Special Features? Lives in colonies (large numbers)
