Because they can't get enough air. Seeds need moisture, air, and some kind of planting medium in order to sprout and grow.

Why do seeds not develop into seedlings if kept immersed in water?

Seeds do not develop into seedlings when immersed in water because they require a balanced environment that includes air, warmth, and proper moisture levels for germination. While water is essential for activating the seed's metabolic processes, excessive water can lead to oxygen deprivation, which is critical for seed respiration. Additionally, too much water can promote rot and fungal growth, further inhibiting seed development. Thus, seeds need a well-drained substrate to germinate successfully.


What is the life cycle of the gymnosperms?

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.


When these are suitable the seeds begin to develop?

germinate


Seeds of temperate plants tend to germinate in?

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.


How does the process of pumpkin growth occur from seed to harvest?

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.


Do sunflower seeds germinate?

What is percent of germinations?

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.


Do I need light to germinate seeds?

Yes, most seeds require light to germinate, but some seeds can germinate in darkness.


Can green bean germinate without sunlight?

Yes, green bean seeds can germinate without sunlight. Germination primarily depends on moisture, temperature, and oxygen rather than light. However, once the seedlings emerge, they will need light to grow effectively and develop properly. Without light, the plants will become weak and may not survive long-term.


What involves soaking and draining seeds and leaving them till they germinate?

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.


Why is it beneficial for the seeds of the mangrove tree to germinate and the seedlings to grow while still on the tree?

Germinating while still on the mangrove tree allows seedlings to take advantage of the tree's nutrients and protection from environmental stresses, such as salinity and strong currents. This strategy increases the likelihood of survival, as the seedlings can develop a stronger root system before being dispersed by tides. Additionally, it ensures that the seedlings are released at an optimal time and place for growth, enhancing their chances of establishing themselves in the challenging coastal habitat.


Where will the mongo seeds germinate faster in water or in a wet cloth?

probably a wet cloth as the seed needs oxygen to germinated and there isn't much of it available if its immersed in water
