The radicle is the embryonic root of the seedling. It is the first part of the seedling to appear and allows the seed to suck up water. The radicle grows downwards due to gravity. This is called positive geotropism or positive gravitropism.

Why is the pressure in the center of the earth greater than the pressure in the mantle?
Because towards the center of the earth, there is more mass on top of it, so there is more pressure. All of the other layers, and the stuff on top of the earth is pushing down on it from all sides. For the mantle, its only the stuff on the top of the earth that is putting pressure on it.
Examples of plants of geotropism?
A tree that is growing on a hill and the roots are growing towards gravity (down)
Are there tunnels from pyramids to center of earth?
There are tunnels under some pyramids BUT these do not go down to the center of the earth they only go down a few tens of meters.
Why people in the south pole don't feel they are standing upside down?
Because gravity doesn't pull youdown, it pulls you towards the earth.if you walked a long way down your street (a VERY long way, to the other end of your country.) would you suddenly be walking diagonally? or on your thighs? no. because you are not being pulled towards the bottom of the earth, but to the center. it's quite hard to explain to someone who doesn't already know. We (yes, we,I'm Australian) don't feel upside-down because as you come to our side of the world, the direction your feet face rotates so that your feet always face the center of the earth.And in fact, you did make up the north is up and south is down, because whoever said north was up? you could draw a map with south on top of the map and it would be just as accurate.
If you dig a hole in the south pole are you digging up or down?
Down. Correct. Down is toward the center of gravity, no matter where you are on earth.
What pull down towards the center of the Earth?
Gravity
Do planes fly uphill from the poles to the equator?
No. Planes fly horizontally, but the concept of horizontal depends on the direction of gravity. Gravity pulls towards the center of the Earth, so "down" at the poles is the same as "down" at the equator, i.e. towards the center of the Earth.
What is meant by center of gravity?
gravity is the force that pulls everything down towards the centre of the earth.
Why does the water from a tap fall down and why it cannot go up?
Gravity pulls objects towards the center of earth's mass. Hence water falls down towards the floor.
How does the earth's gravity hold air around the planet?
Air has mass, and gravity pulls anything with mass. The gravity of the earth "pulls" air down towards it's center.
On the Earth down means toward the Earth's?
center
What is gravity's effect on motion?
Gravity pulls objects together and towards the center of the earth. The force of gravity depends on the mass of the objects and the distance between them. Gravity will speed up objects falling towards the earth and slow down rising objects.

Describe the dirction in which soil and rocks particles to fall?
Things fall in the direction that we call "down". BTW, "down" may point in different "absolute" directions.

A tree that is growing on a hill and the roots are growing towards gravity (down)
What force pulls you down towards the earth?
Gravity
What effect does the force of gravity have on the speed of a ball when you throw it in the air?
Gravity will accelerate any object (aka, the ball) towards the center of the earth, (or "down") at 10m/s2.
