6. Cytoplasm moving – amoeba Oval w/ flagellum/eyespot – euglena
Science Thoughts 2/21
How can you tell the difference between the four protists by looking at them?
Round ball – volvox
Cytoplasm moving – amoeba
Oval w/ flagellum/eyespot – euglena
Oval w/ cilia/oral grove - paramecium

Notes Work on Protist work

8. Amoeba Reproduces through binary fission
They split in half – creates an exact copy of itself.
Moves by stretching its cytoplasm into finger like extensions.
Called pseudopods
Cell membrane is very flexible allowing the amoeba to change shapes easily
Eats by “catching” or “trapping” its food by surrounding it with pseudopods
Eats algae, bacteria, plant cells, microscopic protoza

9. Paramecium
Paramecium are able to move because it is covered with tiny hair like structures called cilia
Cilia also help the paramecium catch its food and direct it into its tiny mouth like opening called the oral groove
Eats tiny algae, plants
Anal pore gets rid of waste
Has two nuclei – one big and one small
Big nuclei operates as the director of the cell
Small nuclei is used only for reproduction
Reproduces with binary fission
Splits in half – creates an exact copy of itself.

10. Euglena Has characteristics that are both plant like and animal like.
Euglena does not have a cell wall, like all other plant cells.
Euglena does have chloroplast which allows the protist to carry out photosynthesis
If there is no light the euglena can also catch food using its flagellum
Euglena is able to move with the help of help of its flagellum
A long whip like tail
Has an eyespot, this allows the protist to detect light.

11. Volvox Lives in spherical colonies – called “parents”
Composed of thousands of cells – each are interconnect and arranged to form a hollow sphere.
Each individual cell has a flagellum, which allows the entire colony move
Eventually the “parent” burst and the daughter colonies spread out to form new colonies.
Can absorb food through the surface or produce food through the process of photosynthesis

12. How do each of the four protist that we are studying obtain energy?
Science Thought 2/22
How do each of the four protist that we are studying obtain energy?
Volvox - autotrophic
Amoeba - heterotrophic
Paramecium - heterotrophic
Euglena – autotrophic and heterotrophic

14. How do each of the four protist that we are studying reproduce?
Science Thought 2/23
How do each of the four protist that we are studying reproduce?
Volvox – asexual and sexual
Amoeba – asexual (rare sexual)
Paramecium – asexual and sexual
Euglena – asexual only
