can u tell me a simple defination of : SEED,EMBRYO,FRUIT AND GRAIN .
Post fertilization of the male and female gamete in the flowering plants,the fusion of the gametes forms an embryo which is the future plant contained in the ovule (egg or female gametes) which gets transformed into the seed.
The ovary gets transformed into the fruit (usually edible).
Grain is a small, one-seeded fruit of cereals like wheat in which the fruit and the seed walls are united.
