Botany or Plant Biology question: Why do the roots of a plant always grow down and the stem grows up? * it has to do with tropism.

Plant roots always tend to grow downward, so a germinating seed can be turned upside-down, and the roots would still grow downward. This is also because of gravity. There are 3 types of geotropism: positive geotropism, negative geotropism, and transversal geotropism.

First, when the fluid contents of plant cells (called the "protoplasm") are pulled downward by gravity, Infrared cameras will automatically photograph the germinating roots. Give it enough water and food and care, and sure enough, its root will grow downward and its stem will sprout upward -- every time! Lay the seed...

At germination, roots grow downward due to gravitropism, the growth mechanism of plants that also causes the shoot to grow upward. In some plants (such as...

Since Darwinian times, scientists have tried to get a handle on how plants are able to direct roots always to grow downward in search of the earth, and shoots to grow upward in search of the sun. So great is the plant's directive that if a root is reoriented to lie horizontal to the surface of the earth, or in other...
