Menstrual Cycle
Menstrual Cycle
A monthly cycle in females, where a mature egg is released. It's a sign of the ability to get pregnant.
Pollination
Pollination
The transfer of pollen from the male part (anther) to the female part (stigma) of a flower, enabling fertilization.
Sexual Reproduction
Sexual Reproduction
The process where sperm and egg cells combine to create a new organism.

Study Notes
Menstrual Cycle
- The mature egg release is called Phase II
- Menstruation is a monthly cycle
- Ovaries are oblong and on the sides of the uterus
- The vagina is the birth canal
- Reproductive organs should be washed daily with mild soap and water
- Ovulation happens around day 14 of a 28-day cycle
Reproduction
- Sexual Reproduction: Involves sperm and egg cells from parents
- Pollination: Transfer of pollen from the anther to the stigma
- Cross-Pollination: Pollen from one flower to another of the same type
- Self-Pollination: Pollen from the anther to the stigma of the same flower
- Flowering Plants: Have stamens (male) and stigmas (female)
- Ovary: Contains developing seeds and becomes larger
- Stigma: Catches and holds pollen grains
- Stamen: Male part of a flower
Animal Life Cycles
- Frogs: egg → tadpole → tadpole with legs → froglet → adult frog
- Mosquitoes: egg → larva → pupa → adult
- Butterflies: lifecycle stages
- Cats: reproductive system includes testicles, vas deferens, and penis
Artificial Vegetative Reproduction
- Methods used to improve plant quality and production
- Stems sprout to grow into new plants
Asexual Reproduction
- New plants grown from plant parts, without sex cells
Plant Adaptations
- Some plants survive in fresh water, others in salt water
- Marine plants make their own food through photosynthesis
- Ecosystems are made by the interactions of communities and their environments
- Mangrove roots provide habitat for plants and animals
