Orange Seed Germination: From Embryo To Seedling

Orange seed germination is a process that involves the development of an embryo into a seedling. The embryo is encased within the seed coat, which protects it from damage. When the seed is planted in soil, it absorbs water and begins to germinate. The first step in germination is the emergence of the radicle, which is the primary root of the seedling. The radicle grows down into the soil, anchoring the seedling and absorbing water and nutrients. The next step is the emergence of the hypocotyl, which is the stem of the seedling. The hypocotyl grows up towards the light, and the first leaves of the seedling emerge from the hypocotyl.
