how do plants know which way to grow

In a plant cell, gravity pulls them to the "bottom," and once they find a resting place, they can send signals to neighboring cells in the plant essentially saying, "OK guys! We now know where Down is. Those of you that need to go down (root cells), go this way!

How do plants know in which direction they need to grow?

All plants can sense the direction of the gravitational field and orientate themselves accordingly. ... In mature plants, phototaxis (growing towards the light source) overrides the gravitational impulse for the stalk and leaves, but the roots – and the seed while it is underground – rely on gravity for orientation.

What determines which plants grow in certain areas?

Climate, soil, the ability of soil to hold water, and the slope, or angle, of the land all determine what types of plants will grow in a particular region. Forests are areas with trees grouped in a way so their leaves, or foliage, shade the ground.

Does it matter which way you plant a seed?

Scott believes that pointing the seed in the right direction (meaning with the root in the down direction) when planting will improve germination rates and vigor of the plant. ... No matter how a seed is planted, the root will orient itself towards the pull of gravity in the downward direction.

In which direction do the roots of plants grow?

One of the key parameters that every plant must respond to is the direction of gravity: stems go up (opposite to the pull of gravity) and roots go down (in the same direction as the force of gravity).

What happens if you plant a seed upside down?

Whether a seed is sown upside down, right side up or on its side, it has the ability to position itself so stems grow upward and roots grow downward. Seeds contain growth hormones that respond to gravity and rotate the seed to the correct orientation.

Can plants grow in pots if they are sideways or upside down?

Growing plants upside down isn't a new concept. Those inverted tomato systems have been on the market for a while and work okay with good cultivation and watering practices. An upside-down garden allows you to grow in smaller spaces and keeps plants out of the soil where pests, like cutworms, can ravage them.
