Page 1: Introduction
Reproduction: process by which organisms produce offspring.
Essential for continuation of species.
Types: asexual (no gametes) and sexual (gametes fusion).
Page 2: Asexual Reproduction
Single parent → genetically identical offspring.
Rapid, no variation.
Methods: fission, budding, fragmentation, regeneration, spore, vegetative.
Page 3: Binary Fission
Parent divides into two equal parts.
Amoeba (irregular), Leishmania (longitudinal).
Page 4: Multiple Fission
Parent divides into many daughters.
Plasmodium under unfavourable conditions.
Page 5: Budding
Small outgrowth (bud) → new individual.
Hydra, yeast.
Page 6: Fragmentation
Body breaks into fragments → each regenerates.
Spirogyra, Planaria.
Page 7: Regeneration
Regrow lost parts.
Planaria, lizard tail.
Page 8: Spore Formation
Spores in sporangium → released → new organism.
Rhizopus (bread mould), ferns.
Page 9: Vegetative Propagation
New plants from vegetative parts.
Natural: stem (potato), root (sweet potato), leaf (Bryophyllum).
Artificial: cutting, layering, grafting.
Page 10: Sexual Reproduction
Two parents → gametes fusion → variation.
Flowers: male (stamen), female (pistil).
Pollination: self/cross.
Fertilisation → zygote → embryo.
Page 11: Human Male Reproductive System
Testes → sperm + testosterone.
Vas deferens → urethra.
Accessory glands: seminal fluid.
Page 12: Human Female Reproductive System
Ovaries → ovum + oestrogen/progesterone.
Fallopian tube → fertilisation site.
Uterus → implantation.
Page 13: Menstrual Cycle
28 days cycle.
Menstruation (day 1-5), follicular, ovulation (14), luteal.
Pregnancy if fertilisation.
Page 14: Fertilisation and Development
Sperm + ovum → zygote.
Implantation → placenta → foetus.
Gestation 9 months.
Page 15: Contraception
- Barrier: condom, diaphragm
- Hormonal: pills
- IUCD: copper-T
- Surgical: vasectomy, tubectomy
