Answer:
Humans and animals have bones to provide support and structure. While plants don't have bones, they do contain a variety of structural cells that have different compositions and functions. In this lesson, we'll be taking a look at collenchyma cells, which help plants stay standing.
Collenchyma cells are elongated cells with irregularly thick cell walls that provide support and structure. Their thick cell walls are composed of the compounds cellulose and pectin. These cells are often found under the epidermis, or the outer layer of cells in young stems and in leaf veins.
