Reproduction
Key knowledge — Reproduction
Key facts & rules
- Sexual reproduction: fusion of male and female gametes → genetic variation.
- Asexual reproduction: mitosis → genetically identical offspring (clones).
- Insect-pollinated flowers: large petals, scent, nectar, sticky pollen, sticky stigma.
- Wind-pollinated flowers: small petals, no scent, large feathery stigma, light/smooth pollen.
- After fertilisation in plants: ovule → seed; ovary wall → fruit.
- Conditions for germination: water, oxygen, warmth (not light).
- Human male gamete: sperm (haploid, mobile); female: egg/ovum (haploid, large, stationary).
- Menstrual cycle: ~28 days; ovulation at day ~14; FSH stimulates follicle; LH triggers ovulation; oestrogen rebuilds uterine lining; progesterone maintains lining.
