Power of Plants: Seeds
Most plants start their lives as tiny seeds. Seeds can be as tiny as a grain of side or bigger than a fingernail. Some are round, while others are flat or tear-shaped. Seed plants fall into two groups, angiosperms and gymnosperms.
Angiosperms are the flowering plants. Their seeds develop inside a female reproductive part of the flower, called the ovary. Which usually ripens into a protective fruit.
Gymnosperms (Conifers, Ginkgo, and Cycads) do not havr flowers or ovaries. Their seeds mature inside cones.
Seeds may be carried away from the parent plant by wind, water, animals, gravity or burst open.
Animals can transport seeds from one place to another when seeds attach to their fur or when an animal eats fruits with seeds. The seeds go through the digestive tract and left in scat.
Seeds can be transported by water. The Coconut is buoyant and water plants like Cattails float.
Dandelions are a perfect example of seeds carried away by wind.
Some seed pods are designed to explode and throw the seeds a good distance from the parent plant, The eneray to burst open has been compared to how a Snap Bracelet coils by Scientists!
The Coco de Mer seed is the largest seed of the plant kingdom, however it does not get too far from it's parent plant. It's large, brown seed falls to the ground below. Too dense to float on water the seed will germinate in the location that gravity places it.
Some seeds need light to germinate. Others need darkness. All seeds need moisture, oxygen and the right temperature to germinate, or grow. Until they have these conditions, the seed remains dormant and does nothing.
A TYPICAL SEED INCLUDES THREE BASIC PARTS: (1) AN EMBRYO, (2) A SUPPLY OF NUTRIENTS FOR THE EMBRYO, AND (3) A SEED COAT.
Inside a seed is an embryo, which is a tiny plant, and the endosperm, which are small leaves which supply the embryo food. The outside of the seed has a seed coat, which protects the embryo from injury or drying out.
