Mature sunflowers do not track the Sun.
Immature sunflower buds exhibit heliotopism. The heliotropic motion of the bud is performed by the pulvinus, a flexible segment just below the bud, due to reversible changes in turgor pressure (no growth).
Many plants are known for their ability to track the movements of the sun by a process called solar tracking or heliotropism. This is sometimes controlled by water movement in and out of cells and plant hormones.
However, cultivated sunflowers will track the sun only when young or in bud. Once mature, the flowers tend to face east. Wild sunflowers do not track the sun.

As to why they face east, no one knows at this time. It is thought it may be to protect young developing seeds from the hot rays of the afternoon sun.
Leaves of many plants track the sun to collect the most light energy for photosynthesis, but photosynthesis has nothing to do with the leaf movements.

What 2 types of stimulus do sunflowers respond to?
Sunflowers primarily respond to two types of stimuli: light and gravity. They exhibit phototropism, where they bend toward sunlight to maximize photosynthesis, and gravitropism, where their roots grow downward in response to gravity, ensuring stability and nutrient absorption. These responses help them thrive in their environment.
How do sunflowers respond to stimulus?
Sunflowers exhibit a phenomenon known as phototropism, where they grow and turn their heads toward sunlight to maximize light absorption for photosynthesis. This movement is driven by differential growth rates on the shaded side of the stem, causing the flower to bend toward the light. Additionally, sunflowers can respond to other stimuli, such as touch or gravity, although these reactions are less pronounced than their response to light. This adaptive behavior enhances their growth and reproductive success in their natural habitat.
What is the electrical charge on the plate that causes the beam to bend toward that plane?
The electrical charge on the plate that causes the beam to bend toward that plane is negative. When a charged particle beam, such as an electron beam, passes near a negatively charged plate, it experiences an attractive force due to the electric field created by the plate. This force causes the beam to bend toward the plate, demonstrating the influence of electric fields on charged particles.
What is the electrical charge on the plate that causes the beam to bend toward that plate?
The electrical charge on the plate that causes the beam to bend toward it is negative. This negative charge creates an electric field that interacts with the positively charged ions in the beam, causing them to be attracted towards the negatively charged plate.
What is the electrial charge on plate that cause the beam to bend toward the plate?
The electrical charge on the plate that causes the beam to bend toward it is negative. When a charged particle or beam, which is typically positive, moves through an electric field created by the negatively charged plate, it experiences an attractive force toward the plate. This results in the beam bending toward the plate due to the influence of the electric field.
How does the coriolis effect influences winds?
The Coriolis effect causes an air mass moving from the North Pole to the equator to bend to the west, or turn toward the right. In the Southern Hemisphere the opposite happens.
Does sunflower bend towards sunlight?
Yes.
How does the Coriolis effect influence?
The Coriolis effect causes an air mass moving from the North Pole to the equator to bend to the west, or turn toward the right. In the Southern Hemisphere the opposite happens.
What is the muscle that causes parts of the body to bend?
A flexor is a muscle that causes a joint to bend. In contrast, an extension is a muscle that straightens a joint.
How does the winds effect the coriolis effect?
The Coriolis effect causes an air mass moving from the North Pole to the equator to bend to the west, or turn toward the right. In the Southern Hemisphere the opposite happens.
