Part A Complete sentences would be good for all of your analysis. KCassidy Oedogonium • Chlorophyta phylum • Filamentous green algae; one cell thick colonies • Usually free-floating; non-motile • Doesn’t eat other organisms; photosynthetic (autotrophic)

Chlamydomonas • Chlorophyta phylum • Single-celled green algae about 10 micrometers in diameter. • Swims with two flagella • Doesn’t eat other organisms; photosynthetic (autotrophic)

Pandorina • Chlorophyta phylum • Exist as colonies made up of 32 individual biflagellate cells • Each individual cell contains flagella which allow the colony to move as a whole • Doesn’t eat other organisms; photosynthetic (autotrophic)

Gonium • Chlorophyta phylum • Colonial algae consisting of 4-16 cells arranged in a flat plate with no pole differentiation • Each cell in the colony is biflagellate, containing two flagella which are used to move the colony as a whole • Doesn’t eat other organisms; photosynthetic (autotrophic)

Ulothrix • Chlorophyta phylum • Filamentous green algae with mostly cylindrical cell body • Become attached to surfaces by a modified holdfast cell • Doesn’t eat other organisms; photosynthetic (autotrophic)

Eudorina • Chlorophyta phylum • Exist as colonies made up of 32 individual biflagellate cells • Each individual cell contains flagella which allow the colony to move as a whole • Doesn’t eat other organisms; photosynthetic (autotrophic)

Oscillatoria • Chlorophyta phylum • Filamentous green algae • Doesn’t move; non-motile • Doesn’t eat other organisms; photosynthetic (autotropic)

Cladophora • Chlorophyta phylum • Exists as a seaweed thalus • Doesn’t move; non-motile • Doesn’t eat other organisms; photosynthetic (autotrophic)

Chlorela • Chlorophyta phylum • Spherical single-celled green algae about 2-10 micrometers in diameter • Free-floating; non-motile • Doesn’t eat other organisms; photosynthetic (autotrophic)

Volvox • Chlorophyta phylum • Spherical colonies of numerous flagellate cells attached to a hollow sphere made of gelatinous glycoprotein • Cells swim in a coordinated fashion by their flagella, which with the assistance of the anterior eye spot, allow the colonies to swim towards a light source • Doesn’t eat other organisms; photosynthetic (autotrophic)

Euglena • Euglenoidea phylum • Spindle-shaped unicellular organisms • Use flagella for transportation  • Mainly autotrophic through photosynthesis; some species can ingest tiny particles of living matter When would this happen? KC   Sirogyra spelling KC • Chlorophyta phylum • Filamentous green algae with chloroplasts forming a helical arrangement; 10-100 micrometers in width • Free-floating; non-motile • Doesn’t eat other organisms; photosynthetic (autotrophic)



Part B

Chaos Chaos • Rhizopod phylum • Amorphous single cell • Psuedopodium • Throwing pseudopodium around prey to capture it and absorbing it into the cell where it is digested

Didinium • Ciliophora phylum • Barrel Shaped unicellular carnivore • Ciliate • Engulfing and paralyzing prey in the cytostome

Euglena • Euglenoidea phylum • Spindle-shaped unicellular organisms • Use flagella for transportation • Mainly autotrophic through photosynthesis; some species can ingest tiny particles of living matter

Amoeba Proteus • Rhizopod phylum • Amorphous single cell • Psuedopodium • Throwing pseudopodium around prey to capture it and absorbing it into the cell where it is digested

Spirogyra • Chlorophyta phylum • Filamentous green algae with chloroplasts forming a helical arrangement; 10-100 micrometers in width • Free-floating; non-motile • Doesn’t eat other organisms; photosynthetic (autotrophic)



Feeding The Amoeba senses the presence of the Euglena when one chances into caressing the cell membrane of this predator. A pocket then begins to form in this place and psuedopods begin to form on all sides of the pocket. Slowly the pocket deepens and eventually only has one opening in which the prey can enter. Once entered the psuedopods close of the opening to finish this carnivorous bear hug of sorts. The prey is now captured in a food vacuole and begins to dissolve under the heavy onslaught of digestive enzymes. Some of the Euglena, however, swim to fast into the Amoeba that they are instantly stuck and it is rather quickly ended for them.

Note: Photos are excellent. They show lots of time and hard work. Analysis could and should have shown a little more research about organisms. Overall very pleased. Extra effort on the video of ameoba Grade 97/100 KCassidy
