Proses yang membagi satu sel induk
menjadi dua sel anak atau lebih

5.  Terjadi pada sel tubuh (somatis) dalam proses
pertumbuhan, perbaikan dan reproduksi aseksual
• Kromosom hasil pembelahan mitosis berpasangan
sehingga disebut diploid (2n) dan bersifat identik
• Ada empat fase dalam pembelahan mitosis yaitu :
profase, metafase, anafase, dan telofase.
Ciri-ciri Pembelahan Sel
 Terjadi pada sel kelamin dalam proses reproduksi
seksual
• Kromosom hasil pembelahan mitosis adalah 4 sel
anakan (4n) tidak bersifat identik
• Ada empat fase dalam pembelahan meiosis yaitu :
profase, metafase, anafase, dan telofase. Namun
terdapat dua kali proses PROMAT.

11. Struktur Organ Reproduksi Pria
ORGAN LUAR
• Penis : Saluran Urin dan Sperma
• Skrotum : Penjaga suhu testis agar
sesuai untuk produksi sperma
ORGAN DALAM
• Testis : Memproduksi Sperma dan hormon
Testosteron
Berfungsi untuk membuahi sel telur yang
menghasilkan gamet dan berkembang menjadi janin
Hormon Testosteron adalah hormon yang
dapat merangsang perubahan fisik pada
laki-laki
• Epididimis : Tempat menyimpan sperma
sementara
• Vas deferens : Saluran sperma dari
epididymis menuju uretra
• Uretra : saluran tempat keluarnya urin dan
sperma
• Vesikula seminalis : menghasilkan zat yang
bersifat basa (alkali), fruktosa, hormon
postagladin, dan protein pembekuan
• prostat :menghasilkan cairan keputihan-putihan
yang terdiri dari
1) Asam sitrat : menghasilkan energi
2) Enzim : Pepsinogen, lisozim, dan amilasi
3) seminal lasmin : antibbiotik
• Kelenjar Cowper : Menghasilkan lender dan
cairan yang bersifat basa dengan fungsi
melindungi sperma dari sifat asam urin yang
tersisa

12. Spermatogenesis
Fakta sperma
• Berlangsung di dalam testis
• Dihasilkan 4 sel sperma yang
fungsional
• Dimulai saat laki-laki mengalami
pubertas
• Berlangsung terus menerus

13. Whoa!
1. Nama organ yang berfungsi sebagai penghasil
sperma?
Quiz time!
2. Pembelahan yang menghasilkan 4 sel anakan,
dinamakan pembelahan apa?
3. Tahap pembelahan meiosis manakan ketika
kromosom saling pindah silang (pertukaran
segmen molekul DNA yang sesuai di antara dua
kromatid?

14. Tugas Kelompok
1. Gambarkan tahapan pembelahan mitosis dan meiosis
2. Tuliskan 4 perbedaan pembelahan mitosis dan meiosis
3. Sebutkan organ luar reproduksi laki-laki dan fungsinya
4. Sebutkan organ dalam reproduksi laki-laki dan fungsinya
5. Sebutkan 3 kelenjar yang bekerja pada sistem reproduksi
laki-laki

15. • Saluran sel ovum, menuju
uterus
• Tempat bertemunya sel
telur dan sel ovum Uterus
Organ reproduksi Wanita Luar :
• Vulva : celah paling luar dari alat reproduksi
Wanita yang dibatasi oleh sepasang bibir
• Labium : sepasang bibir bagian luar Wanita
• Infundibulum
• Untuk menangkap sel
telur
• Mengalirkan darah ke
vagina saat menstruasi
• Mengarahkan sperma ke
Rahim
• Mendukung kepala janin
saat dilahirkan
• Tempat perkembangan janin
terdiri dari 3 lapisan:
o Perimetrium (lapisan luar)
o Miometrium (lapisan Tengah)
o Endometrium (lapisan dalam):
lapisan yang membatasi
rongga Rahim dan meluruh
saat menstruasi
• Tempat produksi sel
telur
Organ Reproduksi Wanita

16. oogenesis

17. Siklus
Menstruasi
• Hormon Estrogen
• Hormon progesterone
• Hormon FSH
• Hormon LH

18. Fase
menstruasi
 Hormon FSH (follicle
stimulating hormone)
adalah hormon yang
dihasilkan oleh
kelenjar pituitary
Fase
Proliferasi
 Fase yang saat dinding
Rahim menebal untuk
mempersiapkan
tempat melekatnya
embrio apabila sel
telur di buahi oleh
sperma.
Fase
sekretori
 Folikel berubah menjadi korpus
luteum
 Apabila tidak terjadi fertilisasi,
korpus luteum tidak
memproduksi hormon estrogen
dan progesterone. Sehingga
mengakibatkan jaringan
penyusun dinding Rahim rusak
dan terjadi pendarahan

20. Proses Perkembangan kehamilan atau embrio

21. Fungsi air ketuban
1. Memberi ruang
gerak
2. Pelindung Janin
3. Cadangan cairan dan
nutrisi bagi janin
4. Menjadi inkubator
5. Membantu proses
kelahiran
6. Sebagai pendeteksi
kelainan genetik
pada janin
Proses melahirkan
Fungsi placenta
1. Memproduksi
hormon kehamilan
2. Memberikan oksigen
serta nutrisi yang
mendukung
perkembangan janin
di dalam kandungan

22. Kembar dizigot Kembar monozigot
Berasal dari satu sel telur dan
satu sel sperma
Dua zigot di buahi oleh dua sel
sperma
Tidak memiliki wajah yang mirip
