Teb: Tapetum: Nws develops thaum lub sij hawm microsporogensis nyob rau hauv lub anther (microsporangium.) Nws muaj nuj nqi yog muab cov khoom noj rau cov qoob loo loj hlob. Synergids: Lawv tsim thaum lub sij hawm megasporogenesis hauv ovule (megasporangium.)
Qhov chaw thiab txoj haujlwm ntawm tapetum yog dab tsi?
Tapetum yog txheej txheej ntawm tes sab hauv hauv lub anther, uas nyob ib puag ncig cov paj paj hlwb (PMCs) thiab / lossis microspores muab khoom noj khoom haus thiab enzymes xav tau rau microsporogenesis thiab paj ntoos maturation.
tapetum function yog dab tsi?
Tapetum yog txheej sab hauv ntawm microsporangium. Nws muab khoom noj rau cov qoob loo loj hlob. Thaum lub sij hawm microsporogenesis, lub hlwb ntawm tapetum tsim ntau yam enzymes, cov tshuaj hormones, amino acids, thiab lwm yam khoom noj uas yuav tsum tau rau kev loj hlob ntawm paj paj noob qoob loo.
Pob tapetum pab tsim lub embryo sac?
Tapetum yog tsim thaum lub sijhawm tsim ntawm microsporangium. Nws yog tsim los ua ib txheej cellular sab nraum cov ntaub so ntswg sporogenous. Nws pab muab khoom noj khoom haus rau microspore. Synergids yog tsim nyob rau hauv lub embryo sac thaum lub sij hawm tus txheej txheem ntawm megasporogenesis.
Dab tsi yog lub luag haujlwm ntawm tapetum hauv anther?
Cov tapetum yog tshwj xeeb txheej ntawm cov khoom noj khoom hauspom nyob rau hauv lub anther, ntawm paj paj, qhov chaw nws nyob nruab nrab ntawm cov ntaub so ntswg sporangenous thiab phab ntsa anther. TapetumNws yog ib qho tseem ceeb rau kev noj haus thiab kev loj hlob ntawm paj paj noob qoob loo, nrog rau lub hauv paus ntawm precursors rau paj paj.
