Chromoplasts muaj nyob rau hauv txiv hmab txiv ntoo, paj, cov hauv paus hniav, thiab kev ntxhov siab thiab laus nplooj, thiab muaj lub luag haujlwm rau lawv cov xim txawv. Qhov no yeej ib txwm cuam tshuam nrog kev nce loj hauv kev sib sau ntawm carotenoid pigments. Kev hloov pauv ntawm chloroplasts rau chromoplasts hauv ripening yog ib qho piv txwv classic.
Chromoplasts pom nyob rau hauv ib tsob nroj nyob qhov twg?
Chromoplasts yog plastids uas muaj xim vim yog cov xim uas tsim thiab khaws cia rau hauv lawv. Lawv muaj nyob rau hauv txiv hmab txiv ntoo, paj, hauv paus, thiab nplooj senescent. Cov xim ntawm cov nroj tsuag no cuam tshuam nrog cov pigments, sib nrug ntawm chlorophyll.
Chromoplast Class 9 yog dab tsi?
Chromoplasts yog plastids thiab muaj carotenoids. Lawv tsis muaj chlorophyll. Carotenoid pigments yog lub luag hauj lwm rau cov xim sib txawv xws li daj, txiv kab ntxwv thiab xim liab imparted rau txiv hmab txiv ntoo, paj, nplooj qub, cov hauv paus hniav, thiab lwm yam. Chromoplasts yuav tsim los ntawm ntsuab chloroplasts.
Chromoplast nyob qhov twg hauv nplooj?
Hint: Cov hlwb cog muaj chloroplasts, chromoplasts, leucoplasts thiab plastids. chromoplast yog liab thiab daj los yog xim. Lawv pom hauv paj paj thiab txiv hmab txiv ntoo.
Qhov twg ntawm cov nroj tsuag muaj ntau cov chromoplasts?
puv puv pericarp hlwb muaj ntau tus chromoplasts, tshwm li ntsuab vim yogtshwj xeeb fluorescence ntawm GFP thaum tsis muaj chlorophyll (Forth thiab Pyke 2006). Qhov loj ntawm plastid txawv ntawm qhov loj hlob ntsuab mus rau theem puv puv, chromoplasts yog me dua chloroplasts.
