how does a fertilised gamete turn into a seed and then a fruit? does a fertilised gamete of a flower turn into a seed and then a fruit?
the fertilised gamete or ZYGOTE becomes the embryo.
the ovule which contained the gamete becomes the seed.
the whole ovary becomes the fruit!!
tomato = fruit.
inside the tomato there are 100s of seeds, each of which came from an ovule.
inside each seed is an embryo (easiest seen in a peanut! split a salted peanut in half and look for the tiny leaves at one end!!) and the embryo came from the zygote.
