The term is applied to the sprouting of a seedling from a seed of an angiosperm or gymnosperm, the growth of a sporeling from a spore, such as the spores of fungi, ferns, bacteria, and the growth of the pollen tube from the pollen grain of a seed plant the fruit is the stored food/starch,etc and contains seeds which can lead to the growth of a new plant The primary function of fruits to a plant is to scatter seeds.

After pollination occurs, the flower develops seeds. The fruit is in fact described as a reproductive organ of plants just like the flower and seed. The seeds remain viable with the intake of nutrients until germination. The embryo is a miniature form of the plant that is fed by the nutrition contained in the endosperm. The seeds.rb file is where the seed data is stored, but you need to run the appropriate rake task to actually use the seed data. There are many different kinds of seeds.

In corns and other cereals, endosperm constitutes a major portion of the seed. Note: If random numbers are generated with rand() without first calling srand(), your program will create the same sequence of numbers each time it runs. The responsibility for supplying seed throughout the region was formerly assigned to the public sector; now “privatized” state enterprises run the activity, with private companies operating in certain segments of the market for particular species or varieties (e.g. Endosperm (structure) Starchy material. They may taste sweeter and be more attractive to animals (laboratory tests have shown this to be likely).
