Fertilisation & Implantation 🚀 1. Journey of the Gametes 🚴‍♂️ + 🥚 During copulation, semen is deposited in the vagina (insemination). Motile sperms race through the cervix and uterus to reach the ampullary region of the fallopian tube:contentReference[oaicite:0]{index=0}. The ovary releases an ovum that also travels to this same ampullary spot. Fertilisation happens only when […]

Menstrual Cycle 🩸 1. Big Picture The menstrual cycle is the regular reproductive rhythm in girls and women after puberty. It starts with the first period (menarche) and usually repeats every $$28/29\text{ days}$$ until it stops forever at menopause (around 50 years). During each cycle only one egg pops out right in the middle! 🎯:contentReference[oaicite:0]{index=0}

Gametogenesis 🧬 Gametogenesis is the process by which the primary sex organs – testes in males and ovaries in females – create functional gametes (sperm and ovum). It happens in two flavours: spermatogenesis and oogenesis. Let’s dive into each! 🎉 Spermatogenesis (in the testes) 🔹 1. Germ-cell journey Spermatogonia (2n = \(46\)) line the inner

Female Reproductive System 🌸 Your body’s reproductive “team” works together to make ovulation, fertilisation, pregnancy, and birth possible :contentReference[oaicite:0]{index=0}. Quick Snapshot 📍 Ovaries — make eggs (ova) & hormones. Oviducts / Fallopian Tubes — guide the egg toward the uterus. Uterus (Womb) — shelters the embryo/fetus. Cervix — narrow gateway between uterus & vagina. Vagina

Human Reproduction – The Male Reproductive System 🤝 The male reproductive organs lie in the pelvic region and work together to make, nourish, store, and deliver millions of tiny, tail-wiggling sperm cells. Let’s tour each part and see how they keep the process running smoothly!:contentReference[oaicite:0]{index=0} 1. Location & Overall Layout 🗺️ A pair of testes

Apomixis & Polyembryony 🌱 1 ‒ Why These Topics Matter Most seeds form after fertilisation, mixing genes from two parents. But some flowering plants have clever shortcuts that skip fertilisation altogether (apomixis) or pack several embryos into a single seed (polyembryony). Understanding these tricks helps breeders create hard-working, high-yield crops and gives NEET aspirants reliable exam fodder.

Post-Fertilisation Structures and Events 🌸 Once fusion is complete, a plant flower shifts focus to building food for the embryo, shaping the young plant, and wrapping everything in a protective fruit. These steps are called post-fertilisation events. 1. Endosperm – the Food Factory 🍚 The primary endosperm cell (formed right after triple fusion) divides fast to create

Double Fertilisation in Flowering Plants 🌸 Flowering plants pull off a clever two-for-one trick called double fertilisation. One visit from a pollen tube sparks both embryo and endosperm formation inside the same embryo sac. :contentReference[oaicite:0]{index=0} Step-by-Step Story 🪄 Pollen tube arrival It slips into a synergid and releases two haploid (n) male gametes. :contentReference[oaicite:1]{index=1} Syngamy

1. Pre-Fertilisation: Structures and Events Before a flower even appears, the plant has already decided to bloom! 🌱 Hormonal and structural changes kickstart the formation of floral primordia, leading to inflorescences and eventually, the flower itself. The flower has two main reproductive parts: Androecium – the male part (stamens) Gynoecium – the female part (pistils)

Flower – the superstar organ of angiosperms 🌸 1. Why flowers matter Flowers captivate us with their colours, scents, and forms, but every feature ultimately supports sexual reproduction. :contentReference[oaicite:9]{index=9} They evolve dazzling adaptations to ensure the final products of sex — fruits and seeds. :contentReference[oaicite:10]{index=10} For humans, flowers carry deep aesthetic, social, religious, and cultural
