Today's Lesson : What Is A Seedling?


What I like to call "my little sprouts" are actually scientifically called in the gardening world "seedlings".  In a nutshell it is the first little greenery you see protruding from the earth after the seeds have germinated underneath ground.

My research into seedlings led me to a short Wikipedia article on seedling that gave basic but rather interesting information,

"A seedling is a young plant sporophyte developing out of a plant embryo from a seed.  Seedling development starts with germination of the seed.  A typical young seedling consists of three main parts: the radicle (embryonic root), the hypocotyl (embryonic shoot), and the cotyledons (seed leaves). " -read the full Wiki article on Seedling

The seedling is yet protected by the seed

"Newly germinated plants are just like chicken eggs in that they carry all the nutrition they require with them in the form of seed leavesthe first leaves that emerge from the soil.  Those are soon replaced by a second set, known as the true leaves.  Seedlings start to require some added nutrition once the seed leaves shrivel off and disappear.  Some seed-starting soil mixes come with a bit of organic matter in them, but if yours doesn't, now is the time to add a teaspoon of vermicompost and sea kelp for good measure." - Gayla Trail, Grow Great Grub

There are different kinds of seedlings, each described by the number of seed leaves (cotyledons) they have, for example monocotyledons (monocots) have one blade-shaped cotyledon, dicotyledons (dicots) have two cotyledons.
