A detailed Summary of seeds

Nature has a very special way of making new plants through 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,

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

embryo. This much water at once can cause the seed to swell so much

pollen from the anthers grip onto the stigma of the flower. The pollen tube

epicotyl, which produces the stem and leaves.

soil. During germination water breaks through the seed coats into the
