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 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.
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.

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.
Why does a flame bend toward the wind?
A flame bends toward the wind because the flow of air carries the heat and combustion products away, creating an area of lower pressure on the windward side of the flame. This pressure difference causes the flame to lean in the direction of the wind.
