Generally the kingdom protista consists of two major group, its protozoa and algae

Resource summary

All about the protist
1 Generally
1.1 Nutrition
1.1.1 Photoautotrophic
1.1.2 Chemoheterotrophic
1.1.3 Mixotrophic use both organic and unorganic compound
1.2 Reproduction
1.2.1 Sexual Fussion -gamate- syngamy process
1.2.2 Asexual Binary fussion
1.3 Morphology
1.3.1 Cytoplasm Pellicle Vacuoles Energy Production Mitochondria-Chemoautotroph Mitochondria+Chloroplast-Phatosynthetic Hydrogenosome-Chemoorganotrophs Contractile vacuole(maintain osmoregulation) Phagocytic vacuoles(ingest food) For support OUter gelatinous ectoplasm Inner fluid
2 Type
2.1 Protozoa (animal-like protist)
2.1.1 Classification Apicomplexa Characteristic *Obligate parasite *non-motile in mature form *Food absorb through other wall Archaezoa Characteristic: 1.Flagellated 2.Move in whiplike manner 3. Free-living 4. Parasitic (live& grow in blood stream-inflammation in brain) Habitat: Fresh water Ciliphora Characteristic *have cilia *have gullet(mouth)/cystostome-ingesting material *Eg: -Paramecium, Balantidium coli Rhizopoda Characteristic: Rhizopoda=Amoebas *move by pseudopods *apply phagocytosis *habitat-marine fresh water
2.1.2 Generally Nutrition obtain through.. Pinocytes Fluid sucked into channel Phagositosis Absorbtion Ingestion via gullet/cytosome Characteristic *no chlorophyll *lack cell wall *Unicellular *parasitic/phatogenic *Aerobic/anaerobic/chemoheterotroph * Diversity May *housed in shell/clothed in scales/naked *pigmented/non-pigmented *parasitic/symbiotic
2.2 Algae (Plant-like protist)
2.2.1 General Characteristic Habitat Reproduction asexual reproduction Fragmentation Thallus breaks -> fragmented parts -> Form new thallus Spores flagellated motile spore=zoospores non-motile spores=apllanospores Binary fission nuclear division followed by cytoplasm sexual reproduction Female structure: oogonia -. eggs male structure: antheridia -. sperms Motillity Distriution of algae Primarily Plantonic suspended in aqueous environment Benthic attached on the bottom of water Neustonic at water surface Terrestrial moist rock, trees, soil
2.2.2 Algal ecology seaweed Provide habitat for marine communities human food(sushi) secondary product alginic acid (ice-cream) carrageenan (agar) Diatomaceous earth (filter/ polishing compound) food base for marine food chain Production of toxic Algal blooms
2.2.3 Taxonomy Chlorophyta (green) *green algae *cellulose cell walls *chlorophyll a & b *store glucose polymers Rhodophyta (red) *Reddish colour *chlorophyll a and b, phycocyanin, phycoerythrin, phycoerythrin *cell wall-cellulose/agar *sexual reproduction *storage materials- glucose polymers *habitat-marine(ocean depths) Phaeophyta (brown) *Brown colour *chlorophylls a & c, xanthophyils * cell wall-cellulose/algin *sexual reproduction *storage materials- carbohydrate *Habitat-marine (coastal water) Chrysophyta (Diatoms) *golden- brown algae *chlorophyll a & c *cell wall- peptin &silica *sexual reproduction *storage materials-oil *Habitat-fresh water Pyrrophyta (Dinoflagellated) *brownish *can cause 'red tides' *chlorophyll a & c *cell wall-cellulose *storage materials- starch *habitat-fresh water Euglenophyta *green colour *chlorophyll a & b, carotene *cell wall- none *no sexual reproduction *storage materials- glucose polymers *habitat-freshwater
