Why are bananas curved? I need this for physics

It's because of the sun! Bananas are curved so they can retrieve sunlight. Bananas go through a process called 'negative geotropism'. Bananas originate in the rainforest, and if they grow towards the small rays of light that pass through the thick foliage, the plant would grow crooked and risk to topple over.

I hope it helps.

Have a great day.

It's because of the sun! Bananas are curved so they can retrieve sunlight. Bananas go through a process called 'negative geotropism'. ... What it means is that bananas grow away from the ground, instead of growing towards it, hence the 'negative' geotropism.

Explanation:

Through cell division, banana plants produce leaves that develop into a pseudostem and produce fruit. The bud forms in the bottom part of the plant and grows up through the centre of the pseudostem to the top. The arrow-shaped bud pushes through the top of the plant and its weight then causes it to change direction and grow towards the ground.

Bananas go through a unique process known as negative geotropism. Instead of continuing to grow towards the ground, they start to turn towards the sun. The fruit grows against gravity, giving the banana its familiar curved shape.

But why? The answer lies in the botanical history of the banana. It originated in the middle layer of the rainforest, where there is little sunlight. If the fruit were to grow towards the small amount of light that penetrates sideways through the vegetation, the plant could overbalance and topple over.

So bananas developed a way of growing towards the light without destabilising the plant

it is easily magnetized.
