Gịnị bụ plastid mkpụrụ ndụ? ụdị plastids

1. Chloroplasts. Basic dvuhmembrannye osisi cell organelles maka photosynthesis. Ha iso nke a thylakoid, nke na-emi odude photosynthetic okụre. Thylakoid ọrụ - dịkwuo ifịk elu nke organelle.

3. Chromoplasts. The ikpeazụ ụdị plastids, nke nwere a pụrụ iche odo, oroma ma ọ bụ ọbụna red. Chromoplasts - bụ ikpeazụ ogbo na mmepe nke chloroplasts ebe chlorophyll na-ebibi, na plastids bụ nanị abụba-soluble carotenoids. Chromoplasts na-ẹdude ke petals nke okooko osisi, mfri eke mfri, na ọbụna na Kporo nke osisi.
