Why is most of the banana leaves torn?

 

Don't know much specifically about the banana plant but I would say that what you are calling torn leaves are actually leaves divided into lobes.

I would first ask on what basis do you say that most banana leaves are torn? How are you defining torn? Is this applicable to all varieties of banana, in all geographical locations?

Actually banana plant leaves do indeed tear naturally as a result of the wind, they tear quite easily, I'm not sure if this serves the plant in any way but it's quite rare to see a banana leaf that is not torn if they are grown under natural conditions.

Perhaps the leaves are thin so the plants in high-wind areas can tear easily to avoid wind damage to the branches, while those protected from the wind, and possibly the sun, retain their surface area to gather more sunlight.

In my are area(South Asia) almost all banana leaves are torn except the very new ones.What about the other areas or your area?
