. Adventures with animals and plants. Biology. PROBLEM 3 How Do the More Complex Plants Reproduce? What are seeds? When farmers want oats, wheat, squash, or beans, they plant seeds. It would be interesting, therefore, to find out what is in a seed. We can do this by studying large seeds such as peas, beans, or corn. When we study these seeds, which differ from others only in size or in other unimportant ways, we find that each seed contains an undevel- oped plant. This undeveloped plant is the embryo. If you put some soaked seeds into moist sawdust or sand you will see, after some days, that t

If you put some soaked seeds into moist sawdust or sand you will see, after some days, that the seed coats have been burst by the growing embryo, which soon develops into a seedling. We speak of this growth as genn'mation of the seed. Exercises i and 2 will help you understand what a seed is. How are seeds formed? It took scien- tists many years to discover just how. Corn Bean.
