Reproduction — Telangana (SSC) Class 10 Science Solutions (Free)

Reproduction is the process by which organisms produce offspring and pass on genetic material. - Asexual reproduction: produces genetically identical offspring from one parent (budding, fission, fragmentation) - Sexual reproduction: involves two parents, produces genetically diverse offspring through fusion of gametes

A flower consists of: - Sepals: protective leaf-like structures - Petals: brightly colored, attract pollinators - Stamens (male): comprise anther and filament, produce pollen - Carpel (female): comprise stigma, style and ovary, contain ovules Pollination: transfer of pollen from anther to stigma

Pollination: - Transfer of pollen grains from anther to stigma - Physical process, does not involve fusion Fertilization: - Fusion of male gamete (pollen nucleus) with female gamete (egg cell) - Results in formation of zygote and seed development

Male reproductive system: - Testes produce sperm - Sperm transported through vas deferens and urethra - Prostate gland adds seminal fluid Female reproductive system: - Ovaries produce eggs - Fallopian tubes transport egg to uterus - Uterus provides site for implantation and fetal development

The menstrual cycle is a monthly reproductive cycle in females lasting about 28 days. - Menstrual phase (days 1-5): uterine lining sheds - Follicular phase (days 6-14): ovarian follicles develop, estrogen increases - Ovulation (day 14): egg released from ovary - Luteal phase (days 15-28): corpus luteum produces progesterone, prepares uterus for implantation
