Techno Protists
Some vocab before we start… Prokaryotic Eukaryotic
Some vocab before we start… Prokaryotic Eukaryotic �Pro = before �Karyo = nucleus �Eu = good/true �Karyo = nucleus �Lack a nucleus �Does not have membrane bound organelles �Has a nucleus �Has membrane bound organelles �Eg. Monerans - bacteria �Eg. Plant and animal cells
Unifying Characteristics �Eukaryotic �Most are unicellular and microscopic (some are colonial) �Most reproduce asexually (binary fission) �Lives in almost any environment that contains water �Move in a variety of ways �Obtain food in a variety of ways
How do protists obtain food? Autotroph Heterotroph Saprotroph • Auto = self • Hetero = other • Troph = nutrition • Using light energy • Ingest organic or inorganic substances that chemicals to will be broken make its own food down for energy • Sapro = decaying E. g. algae (photoautotroph) E. g. slime molds E. g. amoeba, paramecium • Absorbs nutrients from decaying organic matter
The 7 Major Phyla As they are presented in our textbooks…
3 Categories of Protists Plant-like Protists Animal-like Fungi-like Protists (Protozoa) 1. Euglenophyta 1. Sarcodina 1. Slime molds 2. Chrysophyta 2. Mastigophora 2. Water molds 3. Pyrrophyta 3. Ciliophora 4. Sporozoa
Mnemonic Time!
Plant-like Protists �contain chlorophyll and carry out photosynthesis �commonly called algae �four phyla: euglenophytes, chrysophytes, diatoms, dinoflagellates �accessory pigments help absorb light, give algae a variety of colors
Phylum Euglenophyta �Eugleno = good eye / Phyta = plant �Single cells �One or more flagella �No cell walls �Elastic layer called the pellicle �Has chloroplast �Autotrophic (photosynthesis) but becomes heterotropic in the absence of light �E. g. – Euglena (euglenoid flagellates)
Phylum Chrysophyta �Chrys = gold / Phyta = plant �Single cells or grouped (colonies) �Motile and free floating �Cell walls (often with silica) �Chlorophyll and yellow pigment in plastids �Food stored as oil or complex carbohydrates E. g. golden algae and diatoms
Phylum Pyrrophyta �Pyrro = fire / phyta = plant E. g. - dinoflagellates Flagella 3 µm �Single cells with 2 flagella �Thick cell wall �Chlorophyll and other pigments in plastids �Food stored in starch or oil �Causes “red tide”
Animal-like Protists (PROTOZOA) �No cell wall �Heterotrophic (free living or parasitic) �Classified according to means of locomotion into 4 phyla
Phylum Sarcodina �Sarco = flesh �Locomotion by protoplasmic extensions called pseudopodia �Many with shells �Reproduces by fission �Can become cysts when in harsh conditions �E. g. amoeba, foraminifera
Phylum Ciliophora �Cilio = eyelash / phora = bearing �Locomotion by beating of cilia �Cilia also help in feeding �Has a macronucleus and micronucleus �Reproduces by binary fission or conjugation �E. g. paramecium, vorticella, and stentor
Phylum Sporozoa �Sporo = seed / Zoa = animal �Lack locomotive structures �Lack contractile vacuoles �Mostly parasitic �Have sexual and asexual life cycle stages and may infect multiple hosts e. g. plasmodium (malaria)
Phylum Mastigophora �Mastigo = whip / phora = bearing �Locomotion by flagella �Absence of chlorophyll �Parasitic and saprophytic �E. g. trypanosoma (sleeping sickness) 9 m
Kingdom Protista – The Protists
Homework 1. Read front page of coloring sheet “Introduction to Protozoans” and color protozoans on back side. 2. Memorize names of 7 Phyla in Protista and know the literal translation of their phylum name. Entry Slip next class on reading content AND phylum names. REMINDER: DISEASE PROJECTS DUE NEXT CLASS!!!`
