REPRODUKSI SEL
• Terdapat dua jenis pembelahan sel:
– Mitosis berperan dalam pertumbuhan,
perkembangan dan perbaikan sel
– Meiosis berperan dalam fungsi seksual

Pembelahan Sel
Mitosis
• Menghasilkan sel anakan
yang identik secara genetik
(diploid)
• Menghasilkan 2 sel anakan
• Profase-prometafase-
metafase-anafase-telofase-
sitokenesis
Meiosis
• Menghasilkan sel anakanyang berjumlah setengah
jumlah kromosom sel induk(haploid)
• Menghasilkan 4 sel anakan
• Meiosis I : profase I-metafase I- anafase I-Telofase I dan sitokinesis
• Meiosis II: profase II-Metafase II-Anafase II-Telofase II dan sitokinesis
