Plant Stems in Cross Section

Illustration Description

The illustration shows the organisation of tissues in plant stems. Plant stems support and elevate plant organs such as leaves, flowers, and fruits. The stem is composed of three tissue systems that include the epidermis, vascular, and ground tissues, all of which are made from the simple cell types. The xylem and phloem carry water and nutrients up and down the length of the stem and are arranged in distinct strands called vascular bundles. They also contain vascular tissue to conduct water, minerals, and sugar throughout the plant.
