Ob hom loj ntawm meroblastic cleavageyog discoidal thiab superficial. Nyob rau hauv discoidal cleavage, cleavage furrows tsis nkag mus rau lub yolk. Lub embryo tsim ib lub hlwb ntawm lub hlwb, hu ua blastodisc, nyob rau sab saum toj ntawm lub qe.
Dab tsi yog qhov kev txiav txim siab thiab qhov tsis txaus ntseeg?
Vim li no cleavage furrows tuaj yeem tsim tau tsuas yog hauv Page 3 3 thaj tsam disc zoo li tsiaj ncej. Xws li qhov cleavage hu ua discoidal meroblastic cleavage. Piv txwv li: noog thiab tsiaj reptiles. (b) Superficial cleavage - Hauv cov qe centrolecithal, qhov cleavage raug txwv rau peripheral cytoplasm ntawm lub qe. Piv txwv li: kab.
