Diatoms

A teku, da kuma sabo ne ruwa, kazalika da rigar ƙasa girma diatoms. Brown wadannan shuke-shuke ba a yellow-kasa-kasa photosynthetic pigments. A peculiarity na wadannan algae ne cewa su Kwayoyin suna kare daga waje wuya harsashi - frustuloy (harsashi). Tsire-tsire girma duka biyu akayi daban-daban da kuma a cikin mazauna. Suna ciyar da abinci mafi yawa Organic abubuwa a yanayi.

Diatoms da musamman tsarin. Wadannan Kwayoyin kunshi biyu bude yatsun (epiteki da hypotheca). Frustuly bango sanye take da pores ta hanyar abin da na musayar abubuwa da yanayi. Wasu shuke-shuke da Ramin-dimbin yawa bude tare da harsashi iya yin amfani da gamsai don matsawa tare da substrate.

Asali algae, kamar duk masu rai, division. Karbar ɓangare na harsashi na iyaye, a na biyu na cell fara girma rayayye. Duk da haka, tsohon frustula kama burinsu wani sabon daya. Tun da m membrane Kwayoyin kusan m na m girma na algae a kan aiwatar da haifuwa ƙunci kula. Duk da haka, saboda da samuwar auxospore, da abinda ke ciki na shuka Kwayoyin ne iya fita daga cikin harsashi da kuma fara sabon division. A lokaci guda ƙaramin tsara na diatoms zai zama muhimmanci ya fi girma fiye da baya daya.

Jinsunan algae:

• Melozira. Wannan nau'in na zaune a cikin gishiri da ruwa, kuma a cikin ruwa. Su ikon da aka kawota ta hanyar aiwatar da photosynthesis. Wadannan diatoms ne, yafi amfani ga nazarin halittu ruwa analysis, tabbatas da mataki na samu na tafki.
• Gomfonema. Shuke-shuke da wannan jinsin girma a tsabta ruwaye. Su hašawa zuwa algae ko wasu daban-daban abubuwa samu a kasa da kuma gina su mazauna. Wannan irin unpretentious zuwa da zazzabi yanayi. Domin molluscs, wadannan algae ne nutritionally m abu.
• Plevrosigma. Wadannan shuke-shuke da ake samu a ruwan zartsi marine ruwan inda ya zama abincinku matasa kifi.
• Sinedra. Diatoms wannan kungiyar ne guda-celled shuke-shuke. Sun haifar da mazauna kama su siffar a daure fan. Kamar yadda wani ɓangare na da "master" suka zabi kore algae ko plankton. Sinedry mazauninsu - kogi sannu a hankali gudãna da kuma tsaye ruwa. Wannan irin ba dace da kifi abinci mai gina jiki.
• Navicula. Wadannan algae za a iya samu a ko'ina. Sun bayyana a cike da laka kasa na ruwa tare, a kan rigar kankara da kuma ƙasa.
• Pinnulyariya. Diatoms wannan irin da ake samu a cikin cike da laka yankunan tafkunan da Paddy filayen. Saboda ta high jure zafin jiki canje-canje da suka rayu a kusan kowace kusurwa na duniya. Leaf da shuka Kwayoyin suna sosai kiyaye su a cikin laka. Godiya ga wannan fasalin pinnulyarii alƙarya da high viability.

Tsiren ruwan teku kelp girma a cikin Far East da kuma tekun na arewacin tekuna. Su tsawon iya zama daga 2 zuwa 6 mita, mai nisa - 35 cm. shuka so wuri mai duwatsu, ga rayuwar. Dangane da sauyin yanayi yanayi na tsiren ruwan teku rayuwa Hasashen ne tsakanin 2 da 4 years.

Propagated kelp spores na wanda aka kafa ta namiji da mace prothallia. Sun samar da gametes (jam sel). Bayan hadi da ovum fãra daga matasa sporonosyaschaya kelp.

Kelp ne yadu amfani a magani, da dafa abinci da kuma kayan shafawa.

Thallus kelp dauka domin abinci. Na shuke-shuke samu babban salads, soups, breads da sweets. A cosmetology amfani da mai da kuma algae ya'ya. A gaban kwayoyin aidin mahadi za a iya amfani da magani dalilai kelp. The gina jiki inganta assimilation, sha na alli, phosphorus, baƙin ƙarfe, qara sautin na jini.
