What is the magnification? KC Oedogonium is an unbranched filimentous organism with cylindar cells. It is algae. It contains chloroplast and a central vacule. It is often attached to plants or is a free-floating organism. It can have an apical cap at the top of the cell as a result of vegetative reproduction. Reproduces sexually through syngamy.

Cladophora contains chloroplast and is a filamentous algea. It can grow to be up to 13 cm long. It has four flagella. Each filament has multinucleaic segments. The walls are made up of microfibules that lay transversely across each other. They reproduce asexually if conditions are favorable. Chlorella- It is a green algae in the phylum chlorophyta. It is about 2-10 um in diameter, spherical in shape and has no flagella. It is non-motile. Chlorella contains chloroplast. It is photosynthetic.

Chaos Chaos is a Sarcodina (protozoan). It can be 1000-5000 um long. It can sense light and will move away from it. It has multiple nuclei. It reproduces through plasmotomy. Chaos will prey on paramecium. Paramecium are consumed by the pseudopodia enclosing around it. It will break apart the paramecium into small food vacuoles. Chaos move using pseudopodia.

The didinium eats the paramecium. When a didinium touches a paramecium it will latch on with a trichocyst. It will then paralyze the paramecium, ingest it and the cytostome will close. The cytostome will expand to ingest the paramecium. Didinium can be 80-200 um long. It is a ciliate.2 bands of cilia makes it rotate through water. It can be rounded

Eudorina are colonial organisms. Each cell is about 10-25 microns in diameter. Each colony is globular in shape and about 40-50um in diameter. Colonies consist of at least 16 cells contained in a mucilage envelope. Eudorina cells have 2 flagella and chloroplast. The colonies move by simaltaneously beating flagella. They undergo photosynthesis. They also have a contractile vacuole and an eyespot.

Amoeba's move by crawling or in other words they use pseudopods. Amoeba's obtain their food through phagocytosis. Amoeba can be found in the phylum Tubulinea. Most Amoeba reproduce by means of mitosis and cytokinesis.  Which phylum??? K C

Chlamydomonas move using a flagella that comes out in one end of the organism. Chlamydomonas are photoautotrophic organisms that use light as a source of food. They can also absorb nutrients through their cell surface. Chlamydomonas can be found in the phylum Chlorophyta. Chlamydomonas reproduce through meiosis. Very good job on this one! KC

Euglena use a flagellum that comes out at one end of the organism as movement around in it's environment. Euglena are partly heterotrophic and partly autotrophic. Euglena can eat by phagocytosis. Euglena can be found in the phylum Euglenophyta. Euglena can reproduce by mitosis. Why would they becone heterotrophic? KC

Paramecium have cilia that help it to move in it's environment. Paramecium eat small bacteria that are swept by the cilia into the oral groove of the paramecium. Paramecium can be found in the phylum of Ciliophora. The contractile vacuole within the organism helps to regulate osmotic pressure. It has 2 nucleus's that perform different functions within the organism. Macronucleus is used for most of the normal cellular activities like protein synthesis. The micronucleus is used in sexual reproduction.

Spirogyra is a filamentous algae. The nucleus can be transparent. It can reproduce sexually. It is found in freshwater. The outer wall is made of cellulose and the inner wall is made of pectin. They are approximately 10 to 100 um in width and can be centimeters long.

Gonium use 2 flagella to rotate in water. Cells can be oval or angular in shape. They are about 10um in legnth. Contain chloroplast. Picture taken on high power.

Disk-shaped cells can be rounded or tappered. It is a filamentous algae. They move by an oscillating motion around its axis. Oscillatoria uses photosynthesis for food. This picture was taken on high power.



The Volvox is a colonial organism that can be up to 1.5 um in diameter. They have a gelatious cell wall and contain chlorophyl. They move through water with a rolling motion due to cilia. They produce asexually. This picture was taken on high power.

Pandorina generally consist of 6-18 spherical cells (colonial). They have a 2-layer gelatious envelope. It contains 2 contractile vacules. It reproduces by isogamy. This picture was taken on high power.

Group 4 Note: Photos are excellent. You need to tell me magnification for each one.  Anything in red I would like you to rethink or note KCassidy Grade 96/100 ===== [|Our Group's Dabbleboard]
