NCERT Solutions for Class 7 Science Chapter 12: Reproduction in Plants-Summary
CBSE Class 7 Science NCERT Chapter 12 deals with the reproduction in plants, its types and related processes thereto. The two kinds are sexual reproduction and asexual reproduction. Asexual reproduction happens without seeds, on the other hand, sexual reproduction requires seeds. Asexual reproduction produces plants that are genetically identical to the parent plants because no mixing of male and female gametes takes place. So, this is the basic difference between the two types of reproduction in flowers.
Further in this CBSE class 7 science chapter, the types of asexual reproduction are being discussed. The various types include Vegetative Propagation, Budding, Fragmentation, and Spore Formation. The benefit of this type of reproduction is that they take less time, and can produce a replica of for example- if we are taking a white rose, then exactly a white rose plant will be the result.
The most common forms of vegetative propagation are grafting, cutting, layering, tuber, bulb and tissue culture. In budding, an entirely new organism grows on an existing one. Yeasts reproduce via budding. The developing part begins its life as an entirely separate life from the parent plant. Fragmentation is a process in which organisms physically split and completely new which are the resultant genetically identical plants that develop. Algae can be considered the best example of it.
The next important process discussed is Spore Formation. Many plants reproduce via spores as for example- ferns and mosses multiply asexually through the spores. They are microscopic bodies that remain usually spherical in shapes and germinate when the conditions are favorable and grow into the new plants.
The lesson further elaborates the division of the Sexual Reproduction System which comprises the male and female reproductive systems. The flower is the reproductive part of a plant, both the male and female parts are constituted in it. The flower for this purpose is divided into mainly four parts: The Petals, Sepals, Stamen and the Pistil/Carpel. The stamen is the male reproductive part and the Carmel is the female reproductive part.
A flower may contain either a male reproductive organ or of a female and also even both at the same time. So, a flower can be either unisexual or bisexual. Examples of a bisexual flower are China Rose and Rose etc. Then male parts consist of another and filament, and the female organs include the stigma, style and ovary.

Further, this chapter describes Pollination and Fertilization. Again, pollination is of two types – Self-Pollination and Cross-Pollination. In self-pollination, it occurs from a flower of the same plant, and in cross-pollination takes place with the help of certain agents, e.g. insects, water, birds and wind, etc.
Quick Points to remember about NCERT Class 7 Science Chapter 12
- There are mainly two parts of a plant, namely the Vegetative or play a major role in the life cycle of a plant and Reproductive part that play an important role in the reproduction process in plants;
- Reproduction in plants can be divided into two types- Asexual and Sexual;
- There are also many artificial means of vegetative propagation and those are Cutting and Grafting;
- The stamen has two parts- Anthers and Filament. And, the Pistil is divided into Stigma, Style and Ovary;
- The male and the female gametes fuse and form a zygote. The male gametes reach the female gamete by the process of pollination.
