Amyloplasts yog cov nroj tsuag tshwj xeeb organelles lub luag haujlwm rau starch biosynthesis thiab cia. Hauv amyloplasts, hmoov txhuv nplej siab ua cov khoom tsis sib haum, hu ua hmoov nplej nplej (SGs).
Dab tsi yog txoj haujlwm ntawm amyloplasts?
A Amyloplasts
Amyloplasts yog plastids lossis organelles lav phib xaub ntawm cov hmoov txhuv nplej siab. Tus nqi ntawm starch synthesis nyob rau hauv cereal nplej yog ib qho ntawm cov yam ntxwv cuam tshuam rau ob qho tib si grain loj thiab tawm los (Kumar thiab Singh, 1980).
Lub luag haujlwm ntawm amyloplast yog dab tsi hauv kev loj hlob hauv paus thiab tua?
Amyloplasts nyob rau hauv qab ntawm lub hlwb ntawm cov tua thiab cov hauv paus hniav teb rau lub ntiajteb txawj nqus, ua rau calcium signaling thiab tso tawm ntawm indole acetic acidIndole acetic acid inhibits cell elongation nyob rau hauv qis sab ntawm cov hauv paus hniav, tab sis stimulates cell expansion nyob rau hauv tua, uas ua rau tua kom loj hlob upward.
Vim li cas amyloplasts stained?
Lub amyloplast yog qhov sib txawv ntawm plastid lub luag haujlwm rau cov hmoov txhuv nplej siab thiab khaws cia. Starch forms insoluble particles nyob rau hauv amyloplasts, hu ua starch nplej (SGs). SGs tau yooj yim pom los ntawm kev staining nrog iodine tov, thiab lawv tuaj yeem pom tau siv lub tshuab ntsuas lub teeb.
lub vacuole ua dab tsi?
Ib lub vacuole yog ib qho membrane-bound cell organelle. Nyob rau hauv cov tsiaj hlwb, vacuoles feem ntau me me thiab pab sequester khib nyiab. Hauv cov nroj tsuag, vacuoles pab tswj cov dej sib npaug. Qee zaum ib lub vacuole tuaj yeem siv feem ntau ntawm qhov chaw sab hauv ntawm cov nroj tsuag.
