Science / Growth, Development and Reproduction in Plants

Science / Growth, Development and Reproduction in Plants

  • Living things give birth to young ones by the process called Reproduction.
  • Plants reproduce asexually by - Budding, Spore formation, Fragmentation.
  • Vegetative reproduction (vegetative part give rise to new ones) through Leaf or Stem or Root
  • Artificial vegetative propagation - growing plants using artificial methods such as cutting, layering and grafting. Tissue culture is a modern method of vegetative reproduction.
  • Sexual reproduction - Flower is the reproductive part of a plant.
  • Male part of flower is Stamen - filament, anther. Anthers have pollen grains, which are the male sex cells.
  • Female part of a flower is Pistil. It has Ovary, Ovules, Style, Stigma. Ovules contain egg cell.
  • The transfer of pollen grains called Pollination will take place either by self pollination or cross pollination.
  • The fusion of male gamete and female gamete called Fertilisation. Fertilisation results into the formation of zygote. Ovary grows into the fruit, ovules develop into seeds, Seeds contain baby plant called an embryo and reserve food in fleshy cotyledons. Dispersal of seeds take place. Seed germinates under favourable conditions
