seeds

             Nature has a very special way of making new plants through tiny
             things called seeds. Seeds are very important to our lives, from these tiny
             beings the plants, that we need to survive, will grow. A seed is a ripened
             ovule of a plant, this is what produces new plants. The seed is a key part in
             the never ending cycle of reproduction. There are two kinds of seeds,
             To start off you have to know exactly what a seed is. A seed id the
             ripened ovule of a seed plant before it is germinated. There are many parts
             to a seed. The outside layer, which is called the testa, acts as protection for
             the small plant buried inside. The inside part of the seed is known as the
             endosperm. This can be split into two parts. These two parts are known as
             cotyledons or seed leaves. This provides nourishment for the plant when it
             first breaks out of its seed coat and before it has had time to establish its
             roots or make its own food. Buried deep inside is the tiny plant itself, this is
             known as the embryo or germ. Tho tiny now, this small thing will grow into
             a simple flower or a large tree. Attached to the cotyledons are two
             structures. During germination, beneath the cotyledons is the hypocotyle,
             the tip pf this is called the radical. The radical is the first to break out of the
             seed coat and the first true root of the plant. Below the cotyledons is the
             epicotyl, which produces the stem and leaves.
             Before you learn about the process of germination, you have to know
             just where the seed comes from and just how the process works. First the
             pollen from the anthers grip onto the stigma of the flower. The pollen tube
             grows down through the pistil, this pollen tube is the passage way for the
             small pollen grains. The pollen tube allows the pollen grains to reach the
             ovule inside the ovary. When the pollen grain unites with the egg cell the
             zygote is developed, this zygote is what
