Answer:
That's a common myth, but the truth is a bit more complicated! Bananas are indeed curved, but it's not because they grow towards the sun.
Bananas are phototropic, meaning they do respond to light, but they don't necessarily grow towards the sun. In fact, most banana plants don't get direct sunlight because they grow under the canopy of larger trees in tropical forests.
The curvature of the banana actually comes from a process called "negative geotropism." When the banana plant is young, its flowers face upwards, towards the sun. But as the fruit begins to develop, it grows downwards, towards the ground. This is because the weight of the developing fruit pulls it downwards, while the plant's stem continues to grow upwards, in the opposite direction.
As the banana continues to grow and ripen, it becomes more curved due to a combination of gravity and the way the fruit pulp and seeds are distributed within the skin. So, while sunlight does play a role in banana growth, it's not the main reason why bananas are curved!
