what do you think would happen if you put a small seedling in complete darkness for a month but kept all other environmental conditions the same?
If we put a small seedling in complete darkness for a month but kept all other environmental conditions the same the seed will not develop into a seedling because they need solar light during this process.
What is germination?Seedling development or germination refers to the physiological process by which a seed develops into a seedling, which already contains three fundamental plant organs (i.e., roots, shoots and leave). This process (seedling development) requires light.
In conclusion, if we put a small seedling in complete darkness for a month but kept all other environmental conditions the same the seed will not develop into a seedling because they need solar light during this process.
