Conditions Essential For Seed Germination

 

The process in which seed changes into seedling is called as germination of seed.

Conditions essential for seed germination are:

1. Air
2. Warmth
3. Water or moisture
4. Space

If seeds are immersed in water and get sunlight also but do not get air then there will be no growth.

If seeds are placed on moist cotton, it means they receive moisture. If these seeds placed in fridge, it means they do not receive sunlight which means no warmth then also there will be no growth.

If seeds are placed on dry cotton with air and sunlight. It means no moisture as cotton is dry. Then also there will be no growth.

Farmers leave some space between the seeds while sowing them so that plants will not be overcrowded. They must get enough space to get air, water and sunlight for their growth.

Germination occurs at the division of an individual cell. The division of cells occurs because of some signal such as light, temperature, chemical, or physical. The division of cells occurs without the need for fertilization as in sexual reproduction. Flowering plants take about four weeks to form a sporulation, or new plant grows from the original one. Asexual reproduction takes place after the development of new vegetative cells has stopped and the development of a reproductive organ such as the ovary or sperm.

Flowering plants carry life-giving parts called pollen and seeds. Seeds are responsible for producing new plants by allowing the reproduction process to continue. There are three parts of a flower that carry seeds: stigma, base, and petals. Stem means the upper part of the flower where the seed is stored; base is the middle area on the flower where the seed is stored; and petals are the soft part at the bottom of the flower where the seeds are dropped off. Flowering plants have sepals also.
