FAQs on Seeds and Seeds -Summary: (English) Video Lecture - EVS Class 5

1. What are seeds?
Ans. Seeds are small, embryonic plants enclosed in a protective outer covering. They are formed as a result of sexual reproduction in plants and serve as a means of dispersal and propagation.
2. How do seeds germinate?
Ans. Seeds germinate when they receive the right conditions for growth, including water, oxygen, and a suitable temperature. The water activates enzymes in the seed, which break down stored food reserves, enabling the embryo to grow and develop into a seedling.
3. What are the different types of seeds?
Ans. Seeds can be classified into various types based on their structure and mode of dispersal. Some common types include orthodox seeds (able to withstand drying and freezing), recalcitrant seeds (cannot tolerate drying), and wind-dispersed seeds (equipped with structures like wings or parachutes).
4. How long can seeds remain viable?
Ans. The viability of seeds varies depending on the species. Some seeds can remain viable for a few years, while others can remain dormant for decades or even centuries. Factors such as storage conditions, moisture content, and genetic characteristics influence the longevity of seeds.
5. Can seeds be stored for a long time?
Ans. Yes, seeds can be stored for an extended period if kept under proper conditions. The key factors for successful seed storage are maintaining low moisture levels, controlling temperature and humidity, and preventing exposure to pests and diseases. Specialized seed banks and seed vaults are established worldwide to preserve and safeguard plant genetic resources for future generations.
