What is a seed called when it begins to grow by sprouting shoots and roots?
What kind of growth involves roots and shoots but not reproductive structures and occur in most plants?
What kind of growth involes roots and shoots but not reproductive structers and occurs in most plants?
What is the response to gravity called when seeds germinate and roots grow downward and plants grow upwards?
A tropism is a growth response whose direction is determined by the direction of the stimulus. Growth towards the stimulus is called a positive tropism. Growth away from the stimulus is called a negative tropism. The response to light is called phototropism. Shoots are positively phototropic, roots are negatively phototropic. The response to gravity is called gravitropism (or sometimes geotropism). Shoots are negatively gravitropic and roots are positively gravitropic. http://users.rcn.com/jkimball.ma.ultranet/BiologyPages/T/Tropisms.html
These are actually shoots, not roots. If you plant these potatoes in the ground, preferably shoot side up (don't worry, they will find their own way up if you get them upsidedown), the shoots will emerge from the ground and form leaves. Meanwhile, roots will form on the underside of the potato, and eventually new potatoes will be borne as tubers on the roots near the crown. Sooooo...you can turn each of those potatoes into…
