Why is a banana tree not a tree?

Answer 1

Because the roots and trunk don't contain true wood tissue.

Bananas are herbsAlthough referred to as banana trees, they are not trees at all but a perennial herb. Its trunk is not a true one, but many leaves tightly wrapped around a single stem which emerges at the top as the fruit-bearing flower stalk.

The fruit fingers grow in clumps known as hands,since they resemble a hand with fingers. The entire stalk, known as a bunch, takes up to a year for the fruit to ripen enough to be harvested. The original stem dies after producing fruit, but sideshoots rise from the same underground corm to produce a new plant to be harvested the following year. The fruit itself is sterile, unable to produce a plant from the miniscule dark seeds within.

Some banana trees continue producing up to one hundred years, although most banana plantations renew their stock every ten to twenty-five years.

The banana plant belongs to the grasses family.
