After fertilization of the ovule, the megaspore develops into the food supply of the mature seed. After fertilization of the ovule, the <em />integument develops into the seed coat. After fertilization of the ovule, the fertilized egg develops into the embryo of the mature seed.
The ovule contains the female reproductive cells of the seed plants and when fertilized, it produces the seed. Ovules contain megasporocytes, cells that produce megaspores through cell division. An integument is a layer that protects and surrounds the ovule. After fertilization, the integument protects and surrounds the seed. After fertilization, the ovule contains a diploid zygote which develops into an embryo.
Scientists call the organisms that decompose organic matter decomposers, saprobes or saprotrophs. Fungi and bacteria are not restricted to decomposing leaves and other plant materials.
