A woody dicot or gymnosperm root in secondary growth looks similar to a stem in secondary growth. Therefore, see Stem Cross Section - Woody Dicot or Gymnosperm - Secondary Growth. The main difference is there is primary xylem in the center, and the rings are not a clearly defined.

Basic anatomy - ru
All full grown leaves share a basic anatomy, due to their specialized function in photosynthesis. Below we describe the basic anatomy of the leaf using a cross section through the leaf of the ivy, Hedera helix, as an example.
Transverse Section of Stem, Root and Leaf: The stem has wavy hairy outline. The young stem is solid, while the older one is hallow in the centre. Epidermis is single layered, composed of thin walled compactly arranged cells without inter cellular spaces, outer surface is cutinized.
View the prepared slide of a monocot stem and compare with the model. Label the micrographs below: epidermis, ground tissue, vascular bundle, xylem, phloem. 1. Describe the differences between monocot and herbaceous eudicot stems with respect to vascular bundle arrangement. 2. List the basic functions of stems. 3.

The xylem and phloem that make up the vascular tissue of the stem are arranged in distinct strands called vascular bundles, which run up and down the length of the stem. When the stem is viewed in cross section, the vascular bundles of dicot stems are arranged in a ring.
Stems | OpenStax Biology 2e - Lumen Learning
When the stem is viewed in cross section, the vascular bundles of dicot stems are arranged in a ring. In plants with stems that live for more than one year, the individual bundles grow together and produce the characteristic growth rings.
Plant Structures | Biology for Majors II - Lumen Learning
While individual plant species are unique, all share a common structure: a plant body consisting of stems, roots, and leaves. They all transport water, minerals, and sugars produced through photosynthesis through the plant body in a similar manner.
3.3.2: Internal Anatomy of the Primary Stem - Biology LibreTexts
The anatomy of the stem (internal structure) can be examined through longitudinal sections (cutting the stem lengthwise) or in cross sections (cutting a slice of the stem perpendicular to the length). All three tissue types are represented in the primary stem. The epidermis is the dermal tissue that surrounds and protects the stem. The ...
Examine a typical dicot leaf cross-section. Make a drawing, label, and answer the following questions. a. Locate the epidermis (dermal tissue), mesophyll (ground tissue), and vascular bundles (vascular tissue). How is the arrangement of these tissue systems in the leaf different than that in a typical dicot stem or root? b. Identify a vascular ...
