Seedling

What Does Seedling Mean?

A seedling is a very young plant that grows from a seed. When the moisture, light, and temperature conditions are correct, the seedling's development begins with seed germination and the formation of three main parts:

1. Radicle - Embryonic root
2. Hypocotyl - Embryonic shoot
3. Cotyledons - Seed leaves

Maximum Yield Explains Seedling

Seeds require the proper amount of light, temperature, oxygen, and water to germinate and form seedlings. After shooting, the seedling grows gradually while its food storage tissue shrinks. The seedling develops a root system and leaves to begin photosynthesis.

Monocots (one-seed leaves) and dicots (two-seed leaves) differ in early seedling development. In monocots, the primary root is protected by a coating known as a coleorhiza, which pushes off the seed first. Then the seedling leaves appear, also covered with a protective casing known as a coleoptile. On the other hand, in dicots a primary root (radicle) emerges first and anchors the seedling to the ground and permits it to start absorbing water. After absorbing water the shooting emerges. Unlike monocots, dicots emerge above the surface with their seed coat (epigeous germination).
