I-Protozoa

-Delile

• I-protozoa ehlotshisiwe
• I-ciliated protozoa
• I-Sporozoan protozoa
• I-Rhizopod protozoa

I- protozoa noma protozoa zingama-microscopic, ama-unicellular organisations of ezifanayo ezifanayo komunye nomunye. Bahlala ezindaweni ezinomswakama noma ezindaweni ezinamanzi.

Ngokombono we-etymological igama elithi protozoon Inamagama amabili: "proto" okusho ukuthi kuqala kanye ne "zoo" okusho ukuthi isilwane.

Lolu hlobo lwe-microorganism lungabonwa ngeso le-microscope. Zingakhula ziye kufinyelela kumamilimitha. Njengamanje batholakale mayelana Izinhlobo ezingama-50,000 ze-protozoa. Zinomsebenzi lawula amaseli wegciwane.

Indlela yabo yokuphefumula yethulwa ngolwelwesi lweseli futhi basebenzisa izinhlayiya zamanzi ukwenza kanjalo (ngoba bahlala ezindaweni lapho kuhlala khona umswakama). Ziphila ngokudla ulwelwe, isikhunta noma amagciwane.

Imvamisa lolu hlobo lwamaseli lwenzeka ngendlela ye- izimuncagazi ezilwaneni nasezitshalweni.

Bhekafuthi:Kuyini parasitism?

Zizalana ngezindlela ezimbili:

• Ukukhiqizwa kabusha ngokobulili (nge-bi-partition)
• Ukukhiqiza kabusha sexual okungabuye kwehlukaniswe ngu:
  • Ukuhlangana. Ukuzala kwenzeka ngokushintshana ngezinto ezihlukile zofuzo phakathi kweseli nesinye.
  • Isogametes. Lolu hlobo lokuzala lwenzeka lapho ingqamuzana likopisha nelinye eliqukethe izinto zofuzo ezifanayo nezokuqala.

Ukuze unikeze izibonelo zeprotozoa kuyadingeka ukwenza umehluko phakathi kwezinhlobo ezi-4 ezihlukile zeprotozoa.

I-protozoa ehlotshisiwe

Iphakeme ngokuma futhi inohlobo lomsila olunegama le- i-flagella yize ukuhamba kwabo kuvame ukuncipha kakhulu. Kungaba khona kuma-vertebrate nama-invertebrate. Endabeni yabantu, kuyimbangela yesifo sikaChagas. Ezinye izibonelo:

1. I-Trypanosoma Cruzi.
2. U-Euglena.
3. Trichomonas
4. ISchizotrypanum
5. IGiardia
6. I-Volvox
7. Noctiluca
8. Trachelomonas
9. I-Pediastrum
10. I-Naegleria

I-ciliated protozoa

Bahlala emanzini amile amile: amachibi noma amachibi amanzi lapho kunezinhlobonhlobo zezinto eziphilayo. Ezinye izibonelo:

1. IParamecium. Bahamba ngezakhiwo ezimfushane njengezinwele ezincane.
2. I-Balantidium
3. IColpoda
4. I-Paramecium
5. IColpidium
6. I-Didinium
7. Dileptus
8. I-Lacrymaria
9. Blepharocorys
10. Entodinium
11. Iyagoqa

I-Sporozoan protozoa

Bahlala ngaphakathi kwamaseli wezinto eziphilayo (okungukuthi, bangabaphathi babo). Izibonelo zalolu hlobo lweprotozoa:

1. I-IMalarie Plomarium, edluliselwa ngokulunywa umiyane.
2. Ama-Loxode
3. I-Plasmodium vivax
4. IPlasmodium falciparum
5. IPlasmodium ovale
6. I-Eimeria (isici sonogwaja)
7. I-Haemosporidia (ezihlala kumaseli abomvu egazi)
8. ICoccidia ukuthi kuvame amathumbu ezilwane
9. I-Toxoplasma Gondii, edluliselwa inyama ebomvu isesimeni esingesihle noma ingaphekiwe.
10. I-Ascetosporea ebonakala ngokuhlala kwama-invertebrate asolwandle.

I-Rhizopod protozoa

Zihamba ngokunyakaza kwe-cytoplasmic. Banohlobo lwezinyawo ezingamanga.Ezinye izibonelo:

1. Amoeba
2. Entamoeba coli
3. Iodamoeba buetschlii
4. Endolimax nana
