Earth's gravity is the force that guides the direction of a sprouting seed's roots and shoots. (In scientific experiments where plants are put in zero-gravity environments, they grow in all directions.) Roots respond to the pull of gravity (which generates from the center of Earth) by growing toward it, and shoots, or stems, respond to gravity by growing away from it. Scientists do not completely understand how a plant's cells receive the signals that point different parts in different directions, but simple experiments show that no matter which way a seed is planted (with the root-producing part facing down or up), the roots will grow down and the shoots will grow up. Heavy starch grains found in certain cells help the growing plant keep its balance by shifting their place if the plant loses its upright position. This shifting directs growth hormones to affected areas in the plant. These hormones will cause new growth in stems and roots to correct their position in relation to gravity. In the shoot, for example, growth hormones will make cells toward the bottom grow faster than cells toward the top, pushing the shoot upward.

∙ 13y agoYes, plants, seeds, bulbs, etc, use gravity to determine the direction of root and stem growth, even in the absence of light. They may use starch statoliths and their reaction to gravity in this determination. This reaction to gravity is known as gravitropism. Gravity has other effects on plants as well.

∙ 9y agoThe response of a plant seedling to the force of gravity is called gravitropism or geotropism. The seedling's roots grow toward the pull of gravity while the shoots grow away from the force of gravity.

∙ 9y agoGravitropism (also known as geotropism) is a turning or growth movement by a plant or fungus in response to gravity. It is a general feature of all higher and many lower plants as well as other organisms. Wikipedia

What is the survival rate for seedlings?
I would suggest around a 40 - 50% survival rate from seedlings
What is stimulus in plants?
Plants respond to several stimuli. Chief among them are light, gravity, and water. They also respond to temperature and to touch.
How do plant responses help plants to survive?
Some plants grow up and down, the directions being determined by gravity. (stem up, roots down)
What is the region of elongation's function?
The cells produced by mitosis undergo a period of elongation in the direction of the axis of the root. It is at this time that they are sensitive to gravity and respond with gravitropism.
How do plants respond stimuli?
The stimuli that plants respond to include light, water and gravity. Plants grow towards light (phototropism). Also in some plants the flowers will follow the sun as it moves across the sky. Plant roots grow towards water (hydrotropism). Plant roots grow towards gravity/towards the centre of the earth (geotropism). Source(s): I'm a Biology teacher. this is bullcrap it is fake
How does a roots respond to gravity?
how does a root respond to gravity
Does light respond to gravity?
Yes.Yes.Yes.Yes.
Is there any element not respond to gravity?
Gravity acts on all objects with mass, so no. All elements are influenced by gravity.
What is the location of the receptors that respond to gravity?
utricle and saccule
Four steps in transplanting the seedlings?
steps for transplanting seedlings
One plant container holds 14 tomato seedlings If you have 1113 seedlings how many containers do you need to hold all the seedlings?
It is an algebra problem:One container for 14 seedlings should have the same relationship (or ratio) as X containers for 1113 seedlings. So we get:(1 container / 14 seedlings) = (X containers / 1113 seedlings)You should always keep the units as part of the calculations.Using algebra rules we multiple both sides of the equal sign by "1113 seedlings"(1 container / 14 seedlings ) * 1113 seedlings = (X / 1113 seedlings) * 1113 seedlingsgiving(1 container / 14 seedlings ) * 1113 seedlings = X(The "1113 seedlings" in the numerator and denominator on the right side cancel each otherWhich is the same as: X = (1 container / 14 seedlings ) * 1113 seedlingsDoing the math we get:X = 79.5 containers (The "seedlings" in the numerator and denominator cancel each other).you will have 79 full containers and one half filled containersTherefore you will need to have 80 plant containers.
What color are baby seedlings?
There are many differnt colors for baby seedlings.
Do clouds respond to stimuli?
Yes, clouds respond to light by being evaporated from water. By responding to gravity, clouds precipitate back into water. Although clouds respond to the environment, they are not living things.
How do flies respond to gravity and light?
Pretty much the same way as most things.
How will the roots of the growing bean seed plant respond to the force of gravity?
The roots will first go upward, then downward.
What is the primary source of energy for seedlings?
the main energy for seedlings is wind...duuhhh
In order to emerge from the seed and the ground plant seedlings must use turgor pressure and growth to overcome inertia and the force of gravity to break free from the ground what?
shallow planting depth
