Do plant cells have cell walls?!?

Yes. How could there be stems and trunks if there were no cell walls?

Yes, plant cells have cell walls. The cell wall is a rigid structure that surrounds the cell membrane of plant cells. It provides support and protection for the cell, helps maintain its shape, and prevents the cell from bursting when it absorbs water. To verify this information, you can search for reliable sources such as biology textbooks, scientific websites, or academic articles that discuss plant cell structures and their components.
