Cov txheej txheem ntawm kev yug me nyuam asexual sib txawv heev ntawm ntau hom tsiaj

  • Spores. Qee cov protozoans thiab ntau cov kab mob, cov nroj tsuag thiab cov fungi reproduces ntawm spores.
  • Fission. Prokaryotes thiab qee cov protozoa rov ua dua ntawm binary fission.
  • Kev cog qoob loo.
  • Paj tawg .
  • Fragmentation .

Cov lus nug tseem yog, dab tsi yog 4 hom kev yug me nyuam asexual?

  1. Muaj ntau ntau hom kev yug me nyuam xws li fission, fragmentation, budding, vegetative reproduction, spore tsim thiab agamogenesis.
  2. Hauv fission (lossis binary fission), niam txiv cais ua ob lossis ntau tus neeg ntawm qhov sib npaug.
  3. Dab tsi yog 5 hom kev yug me nyuam asexual? Yeej muaj 5 hom kev yug me nyuam asexual. Cov no yog binary fission , tawg , kev yug me nyuam , kev tawg thiab los ntawm spores. Thaum fission , cov ntsiab lus cellular yog replicated nyob rau hauv thiab ces muab faib ua ob tug ntxhais hlwb. Qhov no pom muaj kab mob.
