NCERT Solutions for Class 7 Science Chapter 12:Reproduction in Plants

Atten a trial class for Class 7

The chapter discussed the various methods adopted by plants to reproduce. Asexual reproduction, Budding, Seed dispersal, Sexual reproduction and Vegetative propagation are some of these methods. The process of pollination has also been simplified in this chapter to fit the understanding of Class 7 students. The following are the points discussed in the chapter:

  • Organisms multiply or reproduce their own kind.
  • The two modes of reproduction in plants are asexual and sexual.
  • There are several methods of asexual reproduction, such as fragmentation, budding, spore formation, and vegetative propagation. In vegetative propagation, new plants are produced from different vegetative parts such as leaves, stems, and roots.
  • Sexual reproduction involves the fusion of male and female gametes.
  • A flower is the reproductive part of a plant. A flower may be unisexual with either the male or the female reproductive parts.
  • Pollination is the process of transfer of pollen grains from the anther of one flower to the stigma of the same or another flower.
  • The two types of pollinations are self-pollination and cross-pollination.
  • Pollination takes place in plants with the help of wind, water, and insects.
  • The fusion of male and female gametes is called fertilisation.
