Eukaryotic cells are more complex then prokaryotic cellss the eukaryotic cell structure includes
nucleus: the control center seperating the genetic material, DNA from the rest of the cell.
plasma mambrane: seperating the inside from the outside from the outside of the cell, controls what comes into the cell
cytoplasm: mixture of organic and inorganic materials, fluid portion is called cytosol.
cytoskeleton: "skeleton" with in the cell, maintains cell shape, protects cell, enables some cell motion, is involved in cellular division.
cili and fagella: appendages outside the cell that make it able to move.
ribosomes: tiny cell structures that make protiens, they are attached to the rough ER
mitochindria: is the powerhouse of teh cell
chloroplasts: only plants have this, contains pigment chlorophyll, harnesses the sunlight and turns it into energy.
Algae classifications (plant like)
* phylum Euglenophyta
Euglenoid parts
-nucleus
-choroplasts
-flagellum
-eye spot
-cell membrane
*phylum Diatoms
*Phylum Dinoflagellates
Algae classification ( aniamal like)
*phylum Sarcodina (ameoba)
ameoba parts
-nucleus
-pseudopds (false feet)
-food vacuole
-cell mambrane
-ameoba feeding
*phylum ciliophora (paramecium)
paramecium parts
-macro nulceus
-micro nucleus
-cilia
-food vacuoles
-contractile vacuoles
-oral groove
-cell membrane
*phylum mastigophora (flagellated)
*phylum sporozoa (sporozoans)
*phylum gymnomycota (fungus like protists: slime mold)
there are three groups of slime mold
-plasmodial slime mold: they have enormous single cells with thousands of nuclei
-cellular slime mold: they spend most of there lives as a single celled amoeboid protits.
Protist vocabulary
phytoplankton: the aggregate of plants and plantlike organisms in plankton.
zooplankton: the aggregate of animal or animal like organisms in plankton, as protozoans.
protozoans: any of a diverse group of eukaryotes, of the kingdom Protista, that are primarily unicellular, existing singly or aggregating into colonies, are usually nonphotosynthetic, and are often classified further into phyla according to their capacity for and means of motility, as by pseudopods, flagella, or cilia.
protista: eukaryotic one-celled living organisms distinct from multicellular plants and animals: protozoa, slime molds, and eukaryotic algae
Sarcodines: belonging or pertaining to the protist phylum Sarcodina, comprising protozoa that move and capture food by forming pseudopodia.
Ciliates: Any of various protozoans of the class Ciliata, characterized by numerous cilia.
Flagellates:Any of various protozoans of the subphylum Mastigophora that move by means of one or more flagella. Some flagellates can make food by photosynthesis (such as euglenas and volvox), and are often classified as green algae by botanists. Others are symbiotic or parasitic (such as trypanosomes). Flagellates are related to amoebas.
Sporozoans: Any of numerous parasitic protozoans of the class Sporozoa, most of which reproduce sexually and asexually in alternate generations by means of spores. They are frequently transmitted by bloodsucking insects to different hosts, where they cause many serious diseases, such as malaria and coccidiosis.
nucleus: the control center seperating the genetic material, DNA from the rest of the cell.

This took a really long time to do, probley because i wasnt very focused. The website about eukaryotic cells was very helpfull and had all the information i needed. All of the algae classification stuff i got out of our work sheets, and all the vocabulary i got from dictionary. com! All this stuff i find to be kind of confusing becasue there are so many diffrent types of protists and to me they are all very similar.

black bear!!!
what is a protist?
the name protist mean " the very first." they are eukaryotes because they have a nucleus and most of them have a mitochondria. there are many types of protists one being an amoeba, an amoeba is a single celled organism, some can grow to be a millimeter across. They live in pounds near the bottem, they are well known for the way they move they push themselves forwaord with there cytoplasm and they have no fixed shape. vorticella The single celled verticella attaches itself to a plant, so it is not able to move around still they are able to consume a lot of food, they have little cili on each side that creates a whirlppol type thing that brings in orgainc material. The veritcella's stalk can can coil and uncoil if needed. Euglena is very small about the size of a humans red blood cell. if there are many of these organisms it can turn the pond water green, but they also have animal like charactoristics, because it preforms photosynthesis it needs ligth and it uses a tail like thing called a fagellum to propel itself. Paramecium feed on bacteria and small protists, they look furry because they tiny cili around there whole body. They move together and this is how the paramecium moves, it is able to move four times its length in a second. Volvox can form large colonies, each of them have two flagella and this is what makes them move. Daughter colonies can sometimes be seen in parent colonies. they can preform photosynthesis.
The websight i was one was very helpful and made it easy to do this assignment, becasue it was a video so there were pictures of each organism and a discription about them. the amoeba looks like an egg being cooked, my favoret out of all of these is th Euglena because i think it looks like a mouse. i didnt no there were so many diffrent types of protists i thought there was only one. its cool how they can move from there fagellum or fagellas the way they can move them all at the same time so it prepels them threw the water.
