Reproduction in plants

  1. 1. Reproduction in plants
  2. 2. Types Of Cell Divisions• Mitosis • Meiosis A process of asexual A type of cellular reproduction in which reproduction in which the cell divides in two the number of producing a replica, chromosomes are with an equal number reduced by half of chromosomes in through the separation haploid cell. of homologous chromosomes in a diploid cell.
  3. 3. Types of Reproduction•Sexual reproduction•Asexual reproduction
  4. 4. Flower structure
  5. 5. Male and female parts of flower•Male parts •Female parts -Anther {makes the -Stigma {sticky thing pollen with the sperm that gets the pollen} inside} -Ovule {holds the egg} -Filament {holds up the -Ovary {protects the egg} anther} -Pollen Tube {where the -Stamen {Name for the sperm travels down into anther and filament the ovary} together} 
  6. 6. Pollen Formation
  7. 7. Fertilization
  8. 8. Formation of embryo in plants
  9. 9. Embryo in monocot and dicot
  10. 10. Types Of Flowers
  11. 11. - Bisexual Flowers- Unisexual Flowers
  12. 12. A Bisexual Flower
  13. 13. A Male FlowerThe yellow and pink standing structures are anther andfilament whichindicates the sexof flower eithermale or female .
  14. 14. A Female Flower The flower contains onlythe pistil which clearly indicates that the flower is female one.
  15. 15. Difference between male and female flower Female = pistil Male = stamens
  16. 16. Insects and reproduction• Insect species make up more than two-thirds of allextant animal species, and most insect species use sex for reproduction, though some species are facultatively parthenogenetic. Many species havesexual dimorphism, while in others the sexes look nearly identical. Typically they have two sexes with males producing spermatozoa and females ova. The ova develop into eggs that have a covering called thechorion , which forms before internal fertilization. Insects have very diverse mating and reproductive strategies most often resulting in the male depositingspermatophore within the female, which stores the sperm until she is ready for egg fertilization. After fertilization, and the formation of a zygote, and varying degrees of development; the eggs are deposited outside the female in many species, or in some, they develop further within the female and live born offspring are produced.
