Because they can't get enough air. Seeds need moisture, air, and some kind of planting medium in order to sprout and grow.
Gymnosperms begin their life cycle as seeds, which germinate into seedlings. These seedlings grow into mature trees that produce cones containing seeds. The seeds are dispersed, germinate, and the cycle begins again.

Seeds of temperate plants tend to germinate in the spring when temperatures rise and there is ample moisture available in the soil. This timing allows the seedlings to establish and grow during the warmer months.
The process of pumpkin growth starts with planting seeds in soil. The seeds germinate and sprout into seedlings. As the seedlings grow, they develop vines and leaves. Flowers bloom on the vines, and pollination occurs. The fertilized flowers turn into small green pumpkins, which gradually grow larger and change color as they mature. When the pumpkins are fully grown, they are ready to be harvested and enjoyed.
In order to germinate sunflower seeds hull them. This will cause them to germinate more quickly. Put the seeds in a jar with water and they will germinate.
Yes, most seeds require light to germinate, but some seeds can germinate in darkness.
the percent of seeds which the seed company claims will germinate. if you have seeds claiming to germinate at 80% you will get 800 seedlings for each 1000 seeds sawn meaning you should use 25% more seeds then desired plants (1.25*80%=1). if you got significantly less the declered seed germinating you should complain to the seed company for a refund. .zaf.
Germination involves soaking seeds in water to soften the seed coat and promote moisture absorption. After soaking, the seeds are drained and left in a warm, humid environment to sprout and grow into seedlings.
Yes, sweet basil seeds can germinate in the dark. While some seeds require light to germinate, sweet basil seeds do not have this requirement and can germinate in the absence of light.
probably a wet cloth as the seed needs oxygen to germinated and there isn't much of it available if its immersed in water
Zinnia seeds germinate best when planted directly into well-draining soil with full sun exposure. Plant the seeds about 1/4 inch deep and keep the soil consistently moist until germination occurs, usually within 5-7 days. Thin out seedlings to provide adequate space for growth once they have sprouted.
Seeds do not necessarily need light to germinate, but some seeds do require light to trigger the germination process. Once the seed has sprouted, light becomes essential for the plant to grow and develop properly through the process of photosynthesis.
