Here's why:
* Germination: The first stage of growth is germination. This is when the seed absorbs water and the embryo inside starts to develop.
* Root Development: The first visible sign of growth is usually a root emerging from the seed.
* Seedling Stage: The next step is the development of a seedling, which includes the stem and cotyledons (the first leaves). This process can take several days to a week depending on the seed and growing conditions.
So, while mongo seeds may start to sprout a root within a few days, it will take longer for leaves to appear.
