Why sunflowers face the sun




















When researchers compared mature flowers facing east all day to those that turned west, they found that the stationary blooms attracted upwards of five times more pollinators. If you find yourself at one of the local sunflower fields as dusk nears, see how many younger blooms you can pick out as those sunflowers look towards the setting sun in the west.

By Meteorologist Christina Reis Nationwide. You may have noticed that some sunflowers face a different direction by the end of the day. Researchers have discovered that flowers facing eastward are five times more likely to attract pollinators. Because east-facing blooms warm up more quickly, and bees like those warmer blossoms.

He suggests that a few other factors should be tested for. If sunflowers face east, then their heads are illuminated by the morning sun. The sunlight on the gold of the flowers simply makes them for striking to insect eyes, attracting pollinators to the newly opened flowers of a plant.

Facing the east means the flower will dry out faster from any dew it gathers overnight, reducing the danger from fungal infection. This might seem odd to suggest that the flower could be warmed and cooled, but the sun moves during the day.

Afternoons tend to be hotter than mornings and during this higher temperature period an east-facing flower is a facing away from the sun. Let us tell you that the sunflower flower is more active in summer than in winter. The growth of these flowers is more in those areas, where sunlight stays for more than 6 hours.

Sunflower stays active in hot weather. In the morning, when the sun rises from the east, the direction of the flower is also in the east. Gradually, along with the direction of the Sun, their direction also changes. Our question was, why do sunflower follows the sun? In answer to this question, scientists say that this is due to heliotropism. However, at night, they change their direction again to the east and wait for the sun to rise the next day.

This process goes on regularly. Now the question arises that what would have been heliotropism? Due to which sunflower flowers move towards the direction of the sun.

In a research conducted in the year , it was found that just as there is a biological clock inside humans. In the same way, sunflower flowers also have a special type of arrangement, which is known as heliotropism.

It is also called the biological clock of sunflower. It was also found in this research that these flowers rest at night and become active as soon as they get sunlight during the day.
