All about the protist
- Generally
- Nutrition
- Photoautotrophic
- Chemoheterotrophic
- Mixotrophic
- use both
organic and
unorganic
compound
- Reproduction
- Sexual
- Fussion -gamate- syngamy process
- Asexual
- Binary fussion
- Morphology
- 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
- Type
- Protozoa
(animal-like
protist)
- 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
- 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
- Algae
(Plant-like
protist)
- 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
- 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
- Taxonomy
- Chlorophyta (green)
- *green algae
*cellulose cell walls
*chlorophyll a & b
*store glucose
polymers
- Rhodophyta (red)
- *Reddish colour *chlorophyll a and b,
