  1. WELCOME

  2. I want to grow some plants in my garden Coconut, rose and bryophyllum. Ok.. Let me help you.. Which plants you want to grow? Rahul Rohan

  3. Bryophyllum leaf Look, what i have brought for you Sprouted coconut What?? Rose stem

  4. Why he didn’t give seeds of all these plants? Let us ask our sir.. Is it possible to grow plants without seeds?

  5. Plants can be grown by root, stem, leaf… let us see how?

  6. After few days rahul observed..

  7. WORKSHEET

  8. E A B C Label the plant parts and write its function D

  9. FUNCTIONS

  10. WHY DOES A PLANT PRODUCE FLOWERS?

  11. REPRODUCTION IN PLANTS Sexual reproduction

  12. Parts of a flower Stigma Anther Style x y Filament Ovary Sepals X- STAMEN Y- PISTIL

  13. I have read that stamen is a male reproductive organ Yes!.. And pistil is the female reproductive organ

  14. Stamen Stamens are the male reproductive part Anther contains pollen grains which produce male gametes. Anther Pollen grains Filament

  15. Pistil Pistil is the female reproductive part Stigma Style ovary

  16. Click the correct option X and Y are the parts of Sepal X Stamen Carpel style Y

  17. Click the correct option Identify X and Y x X = filament, Y = anther X = style, Y = stigma y X = anther, Y = filament X = stigma, Y = style

  18. The Flowers Which Contain Either Only The Pistil Or Only The Stamens Are Called Unisexual Flowers. Sunflower Papaya Papaya

  19. The Flowers Which Contain Both The Stamens And The Pistil Are Called Bisexual Flowers. Hibiscus Rose

  20. How the male gamete in the pollen grain reaches the female gamete present in the ovary ?

  21. Pollination The transfer of pollen from the anther to the stigma of a flower is called pollination when pollen of a flower lands on stigma of a same flower it is called self pollination

  22. When pollen of a flower lands on stigma of another flower of the same kind it is called crosspollination

  23. Agents of pollination wind water insects

  24. Wind • Wind pollinated flowers • Not brightly coloured • Do not produce nectar • Pollen grains are light • Ex. Wheat, rice, maize

  25. Water • Water pollinated flowers • Release pollen grains into water • Carried by water current. • Ex. Sea grass, vallisneria.

  26. Insects • Insects pollinated flowers • Have sweet smell • brightly coloured petals

  27. What happens after pollination?

  28. Once pollination occurs a tube grows from the pollen grain down through the style to the ovule stigma style carpel ovary ovule

  29. Fertilisation occurs when the male gamete fuses with the ovule (the female gamete) Male gamete fuses with female gamete (eggs). This process is known as Fertilisation. The cell which results after the fusion of the gametes is called zygote

  30. Male gamete Female gamete zygote The cell which results after the fusion of the gametes is called zygote

  31. REPRODUCTION IN PLANTS ASEXUAL REPRODUCTION SEXUAL REPRODUCTION • POLLINATION • INSECTS • WIND • WATER • Budding • Fragmentation • Spore formation FERTILISATION
