Name the type of plant that has a hard stem.

The stem exists in various varieties in many types of vegetation, both trees and grasses. The difference lies in the fact that in herbaceous plants, it lives literally for several months, in trees, shrubs – up to a hundred years or more. All stems differ in cross-sectional shape, diameter, direction of growth, internal structure (anatomy). The stem or trunk of the tree, the trunks of the bushes, can grow significantly in thickness. All stems perform the function of moving nutrients to the leaves, fruits, and water.
