What do plant stems contain?
Stem usually consist of three tissues, dermal tissue, ground tissue and vascular tissue. The dermal tissue covers the outer surface of the stem and usually functions to waterproof, protect and control gas exchange. The ground tissue usually consists mainly of parenchyma cells and fills in around the vascular tissue.
Why is a plant stem important?
A plant’s stem grows above the ground. The stem carries water, minerals, and other nutrients to and from the roots and leaves. It also supports flowers, if the plant has them, and holds the leaves up to the light.
What makes plant stems grow?
The soil nutrients nitrogen and potassium are responsible for healthy stem growth. The minerals, especially nitrogen, can cause stems to grow too rapidly if they are given in excessive quantities or just before cold weather, when new growth is susceptible to damage.
What does it mean to be a stem?

What does a stem do for plant?
The primary functions of the stem are to support the leaves; to conduct water and minerals to the leaves, where they can be converted into usable products by photosynthesis; and to transport these products from the leaves to other parts of the plant, including the roots.
What does stem do for a plant?
flowers and fruits. The stems keep the leaves in the light and provide a place for the plant to keep its flowers and
What do plant stems do?
Plant stems perform a wide range of functions that have enabled various plant species to survive in different habitats. They provide support for leaves, flowers and fruit and transport water, gases, nutrients and carbohydrates between leaves and roots.
What are the parts of a plant stem?
Stems are structures which support buds and leaves and serve as conduits for carrying water, minerals, and sugars. The three major internal parts of a stem are the xylem, phloem, and cambium. The xylem and phloem are the major components of a plant’s vascular system.
