Seed germination is the process by which a seed develops into a new plant. It requires specific conditions including water, oxygen, and appropriate temperature. The process begins with water absorption (imbibition), followed by activation of enzymes, emergence of the radicle (first root), and finally the growth of the seedling. Different seeds have different germination requirements and timeframes.
Seed Dispersal Methods
Seeds like those of dandelions, maple trees, and cotton have lightweight structures, wings, or parachutes that allow them to be carried by wind over long distances. This method helps plants colonize new areas.
Some seeds have hooks or spines that attach to animal fur, while others are enclosed in fleshy fruits that animals eat and later excrete the seeds in different locations. Examples include burdock and berries.
Seeds of plants like coconuts and water lilies can float on water and be carried to new locations by rivers, streams, or ocean currents. These seeds often have air-filled tissues or waterproof coverings.
