100 Amazing Make-It-Yourself Science Fair Projects
To find what they need, plants mysteriously know in which direction to grow. This
type of growth pattern is called a tropism. The following project demonstrates the
three basic kinds of plant tropisms — hydrotropism, towards water; geotropism, ...
This is a plant's normal response to gravity, and it is called geotropism (or
gravitropism). In general, shoots grow away from gravity and are described as
negatively geotropic. Roots tend to grow towards gravity and are therefore
positively ...

Plant Hormones and Plant Development
Geotropism of coleoptiles, the polar regeneration of roots on cuttings, apical
dominance, and -much later- the polar differentiation of vascular cells were all
shown to involve auxin. And after the commercially available indole-3-acetic acid
(IAA) ...

Design in Nature: Learning from Trees
This mechanism is called geotropism. Geotropism: Stand Up Straight!
Geotropism, or more accurately negative geotropism, gives the side branches
and also the trunk the command: grow erect against gravity. Now, if the leading
shoot dies, the ...
Growth with respect to gravity is geotropism; growth with respect to light is
phototropism. One theory to explain these tropisms, the Cholodny-Went theory,
suggests that both are controlled by auxins, of which indole-3-acetic acid (IAA) is
the ...

This is called negative geotropism. The roots will still grow down towards gravity.
This is called positive geotropism. It is an advantage for shoots to grow away from
gravity. The leaves and stems are lifted above the ground. Roots need to grow ...
