This Amoeba is a flexible active Protist that is able to move freely by
using Pseudopods and is in the phylum Sarcodine.



  • To gain nutrition and energy the amoeba takes in prey with its pseudopod by surrounding their meal. Then it is able to digest the meal in its food vacuole.
  • They would normally snack on particles of food and even other cells.
  • An amoeba is able to reproduce asexually by mitosis annd cytokinesis, which will result in an exact copy of its DNA in the offspring.

  • The Paramecium uses cilia for transportation which act like oars. They beat in a regular pattern, to create movement
  • For food intake, Paramecium can also use its cilia, to pull the prey into its oral groove and then its gullet. The food then becomes a food vacuole and is digested.
  • Paramecium produces asexually as well, by binary fission (Pg. 475 in Biology book) and also conjugation (Pg. 502 in Biology book)


plasmodium.jpg












This Plasmodium is a parasitic protist
and is in the phylum Sporozoan.


  • Trypanosoma and Plasmodium are parasitic
  • The Plasmodium moves by the flow of blood in an organism, the trypanosoma uses flagella
  • Plasmodium reproduce by spores asexually ; Trypanosoma by Meiosis sexually

Seaweed (Phaeophyta) can be used for toothpaste and even pudding

Algae
  • Volvox.jpgAll algae are autotrophic
  • Euglena, Chlorophyta - benefit Food web
  • The volvox at the right is a colonial algae
  • Diatoms - most abundant
  • Pyrrophyta - red tide, food poisoning
  • Rhodophyta - argar, coral reefs
  • Phaeophyta - food alginates, ice cream and pudding
  • Algae consists of Euglenophyta, Bacillariophyta, Pyrrophyta, Rhodophyta, Phaeophyta, and Chlorophyta
