PROTOZOA (Tek h\u00fccreliler)<\/p>\n
Protozoa (Protista) \u00fcyelerinin tek ortak \u00f6zelli\u011fi, bir h\u00fccreli olu\u015flar\u0131d\u0131r. Bir protozoan h\u00fccresi, bir metazoan h\u00fccresinden \u00e7ok daha karma\u015f\u0131k yap\u0131l\u0131 olabilir. \u00c7\u00fcnk\u00fc protozoa’da h\u00fccrenin kendisi bir organizmad\u0131r.
\nProtozoa’n\u0131n s\u0131n\u0131fland\u0131r\u0131lmas\u0131, v\u00fccut i\u00e7i organelleri ve hareket organellerine g\u00f6re yap\u0131l\u0131r. Hemen hemen t\u00fcm Protozoa \u00fcyeleri h\u00fccre duvar\u0131na sahip de\u011fillerdir, aerobik solunum yaparlar ve su olan her yerde bulunabilirler. <\/p>\n
Kloroplast i\u00e7eren t\u00fcrler, foto-ototrof \u00f6zellik g\u00f6sterir. Baz\u0131lar\u0131 ise kloroplast i\u00e7ermelerine ra\u011fmen organik besinlerle de beslenirler (Mixotroph). Euglena buna en g\u00fczel \u00f6rnektir. Tatl\u0131 sularda ya\u015fayan bir h\u00fccrelilerde, Kontraktil Vakuol ad\u0131 verilen bo\u015falt\u0131m organeli bulunur.<\/p>\n
Protozoa \u00fcyeleri 4 phylum (\u015fube) i\u00e7erisinde incelenir:<\/p>\n
Phylum (\u015eube): Sarcomastigophora (K\u00f6k bacak ve kam\u00e7\u0131 ta\u015f\u0131yanlar)<\/p>\n
Bu \u015fubenin \u00fcyeleri, hareket organeli olarak k\u00f6k bacak veya kam\u00e7\u0131 ta\u015f\u0131rlar. T\u00fcm\u00fc bir h\u00fccreli olan sucul canl\u0131lard\u0131r. Kam\u00e7\u0131 veya k\u00f6k bacak ta\u015f\u0131malar\u0131na g\u00f6re, 2 alt \u015fube i\u00e7erisinde incelenirler.<\/p>\n
(Kam\u00e7\u0131l\u0131lar)<\/p>\n
Hareket organeli olarak kam\u00e7\u0131 ta\u015f\u0131yan bir h\u00fccreli canl\u0131lard\u0131r. Baz\u0131 t\u00fcrlerde, koloni halinde ya\u015fam da g\u00f6r\u00fclebilir. Klorofil ta\u015f\u0131y\u0131p ta\u015f\u0131mamalar\u0131na g\u00f6re, 2 s\u0131n\u0131fa ayr\u0131l\u0131rlar.<\/p>\n
K\u00f6k bacakl\u0131lar)<\/p>\n
Bu alt \u015fubedeki canl\u0131lar, hareket organeli olarak k\u00f6k bacaklar ta\u015f\u0131rlar. Besin, pseudopod yard\u0131m\u0131yla ve fagositoz yolu ile al\u0131n\u0131r.
\n\u0130\u00e7eri\u011fine ve \u015fekline g\u00f6re, ba\u015fl\u0131ca 4 k\u00f6k ayak tipi g\u00f6r\u00fcl\u00fcr:
\n1. Lobopod: Lob \u015fekillidir ve hem ektoplazma hem de endoplazma i\u00e7erir.
\n2. Filopod: \u0130plik \u015feklindedir ve sadece ektoplazma i\u00e7erir.
\n3. Retik\u00fclopod: A\u011f \u015feklindedir ve sadece ektoplazma i\u00e7erir.
\n4. Aksopod: \u0130\u011fne \u015fekillidir ve mikrot\u00fcb\u00fcl i\u00e7erir. <\/p>\n
2. Phylum (\u015eube): Apicomplexa<\/p>\n
\u015eubenin neredeyse t\u00fcm \u00fcyeleri endoparazitiktir. \u015eubenin ismi, h\u00fccrelerin u\u00e7 k\u0131sm\u0131nda bulunan ve konak canl\u0131n\u0131n v\u00fccuduna giri\u015fte rol oynayan “apicomplexa” (rhoptry ve mikronem) olarak bilinen yap\u0131lardan gelir. Bu canl\u0131lar\u0131n hareket organelleri, sadece baz\u0131 h\u00fccre aras\u0131 evrelerde belirgindir. \u00dcreme, uzant\u0131 ta\u015f\u0131mayan sporlar veya oocyst ile ger\u00e7ekle\u015fir.<\/p>\n
3-Phylum (\u015eube): Microspora<\/p>\n
\u015eubenin t\u00fcm elemanlar\u0131, zorunlu h\u00fccre i\u00e7i parazitleridir. Mitokondrileri bulunmaz ve tek h\u00fccreli sporlar meydana getirirler. B\u00f6cekler i\u00e7in patojen olan canl\u0131lar\u0131n \u00e7o\u011fu, bu \u015fubenin \u00fcyeleridir. Hayat evrelerinde hem h\u00fccre i\u00e7i hem de h\u00fccre d\u0131\u015f\u0131 ya\u015fam g\u00f6r\u00fcl\u00fcr. H\u00fccre i\u00e7i e\u015feyli ve e\u015feysiz devreler boyunca, konak canl\u0131ya zarar verilir. Sonu\u00e7ta da, \u00e7ok dayan\u0131kl\u0131 bir spor h\u00fccresi \u00fcretilir.<\/p>\n
4-(Silliler)
\nEn geli\u015fmi\u015f protista grubudur. \u00c7ok say\u0131da mikron\u00fckleus (k\u00fc\u00e7\u00fck) ve tek bir makron\u00fckleus (b\u00fcy\u00fck) ta\u015f\u0131rlar. Mikron\u00fckleus \u00fcremeden sorumludur ve mitotik b\u00f6l\u00fcn\u00fcr, makron\u00fckleus ise metabolizmadan sorumludur ve amitotik b\u00f6l\u00fcn\u00fcr.
\nSililerde bulunan protein yap\u0131daki zara “pelikula” ad\u0131 verilir ve pelikulan\u0131n kal\u0131nl\u0131\u011f\u0131, t\u00fcrlere g\u00f6re de\u011fi\u015fkenlik g\u00f6sterir.
\nBo\u015falt\u0131mdan, kontraktil vakuol sorumludur.<\/p>\n","protected":false},"excerpt":{"rendered":"
