Euglena oluhlaza - isitshalo noma isilwane?

Euglena oluhlaza - a isilwane owumphumela, atholakala fresh amile amanzi, emaxhaphozini, emiseleni, amaxhaphozi. Umbala okuqukethwe umzimba ngenxa inani elikhulu chloroplast ku cytoplasm. Ngakho-ke, kubonakala sengathi amanzi "izimbali zawo ziwukudla" lapho ngokweqile buhlanjululwe euglena oluhlaza kuwo.

Isakhiwo kube nzima kancane kakhudlwana lapho kuqhathaniswa amoeba. Bobabili babe protoplasm futhi nucleus. Nokho euglena oluhlaza ngaphandle ungqimba pellicle namanje embozwe - emgodleni nezimo. Umzimba ukuma sifana lokuphotha, blunt ngakolunye uhlangothi side - nomunye. Ekhosombeni iyahola amahlamvu msila encane. Kukhona abomvu "iso" okugqamile ukuthi usabela ukukhanyisa futhi ngaleyo ndlela kusiza iseli ukukhetha yekuhambisa sandla. Eceleni kuba vacuoles. Ngenxa uphawu udonga lwangaphandle ukuma isilwane akuyona kakhulu washintsha, kungase kancane kuphela, ngaphakathi kwemingcele ethile, cindezela bese uyaqondisa. Lokhu isakhiwo Euglena izimbangela oluhlaza futhi indlela yokuhamba. Umsila kokwenza ukunyakaza ukujikeleza, uyisidalwa ezincane kunalokho ngokushesha aphinde abhukude abuyele. Kukhona izinhlobo ukwenza undulation umzimba futhi ngaleyo ndlela yini ukuntanta. Kungani lokhu kwenzeka, akucacile. Izazi zezinto eziphilayo iziphakamiso ezimbili kule ndaba. Ngakolunye uhlangothi, kungase kube ubuhlobo phakathi organelles futhi Euglena amaprotheni sesigcilikisha okuyizinto ngaphansi pellicle futhi kungenzeka shwabanisa. Ngakolunye uhlangothi, umuntu owenza lolu hlobo ukunyakaza kungahle kubangelwe isikhwehlela ethakwa ngu iseli.

Euglena udle ikani oluhlaza kanye isilwane nesitshalo. Indlela, ngalo ekhetha incike ukukhanyisa. cytoplasm wayo inamaseli engaphezu kwamashumi amabili okusaqanda - chromatophores. Ababona, njengoba sekushiwo, futhi namabala amaseli oluhlaza. Ntambama, usebenzisa i-chlorophyll eziqukethwe chromatophores, euglena oluhlaza bakwazi ukubamba iqhaza kwe-photosynthesis, carbon befunda idinga kanye izitshalo - carbon dioxide. Ngakho emzimbeni walo kusuka inorganics akha izakhi efana isitashi futhi imali in the form of okusanhlamvu ku cytoplasm. Ebusuku, lo cell kungenziwa inikwa amandla yi ngendlela efanayo njengoba isilwane. Umzimba womuntu ungakwazi usebenzisa vacuoles ngokushesha kusetshenzwe izinto zemvelo amadamu okuyinto ngokwanele kakade ifomu siphela. Kunjalo amoeba. Futhi ukungayinaki echibini, abaningi balaba izinto ezingaphezu. Uma euglena oluhlaza ebumnyameni isikhathi eside, chlorophyll uyanyamalala chromatophores. Ngakho, coloration ubalekela futhi yezinyoni, it is decolorized ngokuphelele.

Kukhona izinhlobo ngokuvamile okuthiwa i-photosynthesis ezingezona ezemvelo, bakwazi ukudla izilwane kuphela. Baze athuthukile uhlobo mouthparts ngoba ukungenisa ezincane izinhlayiyana zokudla.

Ukukhetha lokhu umzimba uyakwazi amandla waphinda kubonisa ukuba ososayensi ukuthi izilwane nezitshalo babe umsuka efanayo.

euglena okusakazwa oluhlaza division longitudinal esitokisini ngokwayo: emva cytoplasm ihlukaniswe halves ezimbili futhi ekujuleni kwenhliziyo. Ngamunye uvele ukhula msila entsha. Ngaphansi kwezimo ezikahle, Euglena oluhlaza ezifuywa kangangokuba amanzi futhi siba umbala ezifanele. Kukhona ezinye izinhlobo zalezi zinto owumphumela ukuthi ivela, ngokuphawulekayo ingashintshwa ukuze aphile ngisho emakhazeni. Ngenxa yalokho okuzivumelanisa ezinjalo esikhathini mass ukukhiqizwa kabusha iqhwa zabo ngesineke hhayi kuphela oluhlaza, kodwa futhi obomvu, ophuzi ngisho okwesibhakabhaka.

Kukhona futhi euglena kabani amaseli agcwele carotene. Basuke ngesineke amachibi obomvu noma umbala onsundu. .. Lapho imifula, amachibi, emaxhaphozini, njll wome noma nqabela, euglena oluhlaza ilahlekelwa lo msila laphetha, embozwe igobolondo obukhulu - ngesikhathi uguqulwe simila. Kuleli fomu kungaba ulinde izimo ezikahle endaweni efanayo noma kwenziwe kanye uthuli.
