Class 7 Science Chapter 12 Reproduction in Plants: Important Topics
Reproduction in plants takes place sexually and asexually as well. However, the majority of flowering plants reproduce sexually. The flower is the reproductive part of a plant i.e., both male and female gametes are produced by flowers.
- Modes of Reproduction: There are different modes of reproduction based on the number of parents involved. Every living organism reproduces either by sexual reproduction or by asexual reproduction.
- Sexual reproduction is referred to as the mode of reproduction in which gamete cells from two organisms, one male and one female, combine to form a singular zygote.
- Asexual reproduction is the mode of reproduction that includes only one organism. The offspring that is produced is genetically identical to the mother and almost always possesses the same number of chromosomes.
- Fruits and seeds are formed by fertilization. In angiosperms, two structures are formed due to double fertilization – a diploid zygote and a triploid primary endosperm cell.
- The zygote develops into an embryo, while, the endosperm cell gives rise to endosperm. It provides nourishment to the growing embryo.
