1. Reproductive techniques used in Kingdom Protista Por :Arturo Torres, Santiago Fung y Karen Rumay

2. Introduction Reproduction in protists is mostly asexual, this process is called Binary Fission. A very small amount of Protists reproduce sexually. Reproduction in protists is mostly asexual, this process is called Binary Fission. A very small amount of Protists reproduce sexually. Protists don’t form embryos. Protists don’t form embryos. Types of sexual reproduction: Isogamy, Anisogamy, Oogamy. Types of sexual reproduction: Isogamy, Anisogamy, Oogamy.

3. Characteristics Most Protists are unicellular, only a few amount of Protists are multicellular. Most Protists are unicellular, only a few amount of Protists are multicellular. There are over 60000 known species of protists. There are over 60000 known species of protists. Protists have been classified into 3 groups: Algae, Protozoa, Slime Moulds Protists have been classified into 3 groups: Algae, Protozoa, Slime Moulds

4. Protists reproduce

5. Protista can divide to produce more cells.This is a kind ofd reproduction that not needs sex so we call this kind of reproduction asexual reproduction.Protist use a process called mitosis (prophase,metaphase,anaphase and telaphase). In interphase, the genome is relicated. In prophase, the chromosomes condense and the nuclear envelope breaks down.

6. In metaphase, the chromosomes are attached to the spindle fibers and are pushed to the middle of the cell. In anaphase, the spindle fibers pull the chromosomes apart, the centromeres separate, the sister chromatids are pulled to opposite ends of the cell. In telophase, the chromosomes are resurrounded by a nuclear envelope, and the chromosomes decondense.

7. The euglenoids are unique in these organisms in their cell division. The chromosomes remain condensed for much of the cell cycle and the nuclear envelope never really disappears. The ciliates also have a process for recombination of genomic information. We might call this sexual, but it works in a way that is very different from the usual concept for sexual reproduction.

8. Protozoa These protists are animal-like, especially in their nutrition. They ingest their food by phagocytosis. Some have mouth-like structures into which the prey is put while others use pseudopodia to move and to engulf prey. Typical prey include bacteria and other smaller unicellular organisms. phagocytosispseudopodia

9. Animal-like  Animal-like Protists are called Protozoans(unicellular and parasitic)  Digestion in Protozoans is intracellular(trough diffusion)  Most reproduce trough asexual reproduction (Binary Fission) and some reproduce trough sexual reproduction.

10. Plant-like  Plant-like Protists have chlorophyll  They are multicellular and unicellular  However, multicellular as unicellular have no organs or tissues.

11. Fungi-like  Fungi-like protists are divided into three groups: Mixomycota, Acrasiomycota, Oomycetes.  As Animal-Like Protists Fungi-Like Protists’ system is intracellular( trough diffusion).  Reproduction can be asexual ( trough spores) or sexual (alternation of generation)  http://www.tvdsb.on.ca/Saunders/courses/Online/SB I3U/Diversity/Protista%282007-01%29.pdf
