Nyob rau hauv ib qho anther, cov hlwb ntawm endothecium txhim kho fibrous thickening los ntawm cov phab ntsa sab hauv tangential mus rau sab nrauv phab ntsa… Qee lub hlwb endothecium, tawm tsam qhov kev faib ntawm ob lub sporangia, ua nyias-walled. thiab tsim lub stomium, qhov chaw uas cov paj ntoos nplej tau tso tawm thaum lub sij hawm dehiscence.
Lub luag haujlwm twg yog Endothecium hauv kev dehiscence ntawm anther?
Anther dehiscence yog qhov kawg ua haujlwm ntawm tus anther uas ua rau tso cov paj ntoos nplej… Cov ntaub so ntswg no feem ntau yog ib mus rau ob peb txheej tuab, nrog cov cell phab ntsa ntawm cov tuab tuab vim tsis sib xws lignification.
Yuav ua li cas pab kom dehiscence ntawm anther?
Note: Endothecium yog txheej ntawm phab ntsa anther uas pab hauv anther dehiscence. Endothecium cells tsim cov fibrous thickenings uas tawm los ntawm cov phab ntsa sab hauv tangential thaum loj tuaj.
Lub luag haujlwm ntawm Endothecium yog dab tsi?
Lub luag haujlwm tseem ceeb ntawm endothecium yog ntawm kev tsim cov paj ntoos nplej hauv anther. Raws li ib feem ntawm pollen txoj kev loj hlob, lub cell hauv ob sab phlu ntawm anther lumen hu ua endothecium. Nws secretes cov khoom uas yog ib qho tseem ceeb rau kom zoo maturation ntawm paj ntoos nplej nyob rau hauv cov nroj tsuag.
Pab phab ntsa twg pab tiv thaiv tus kabmob?
Assertion: Endothecium txheej ntawm phab ntsa phab ntsa plays lub luag haujlwm tseem ceeb hauv dehiscence ntawm anther Yog vim li cas: Muaj cov fibers bands thiab defferential expansion ntawm sab hauv thiab sab tangential phab ntsa ntawm endothecial hlwb ua rau dehiscence ntawm anther.
