- Definition of the Cortex. Let's explore the cortex layer in more detail. The cortex is defined as root and stem tissue found between the epidermis and vascular tissue of a plant. When you eat potatoes or carrots you are actually eating the root of a plant's cortex.

Cortex Cortex, in plants, tissue of unspecialized cells lying between the epidermis (surface cells) and the vascular, or conducting, tissues of stems and roots. Cortical cells may contain stored carbohydrates or other substances such as resins, latex, essential oils, and tannins.

Plant stem Plant stem. A stem is one of two main structural axes of a vascular plant, the other being the root. The stem is normally divided into nodes and internodes: The nodes hold one or more leaves, as well as buds which can grow into branches (with leaves, conifer cones, or inflorescences (flowers)).

xylem a plant tissue that conducts water and mineral salts from the roots to all other parts, provides mechanical support, and forms the wood of trees and shrubs. It is of two types (protoxylem and metaxylem), both of which are made up mainly of vessels and tracheids See also protoxylem, metaxylem.

Tension Headaches A tension headache is the most common type of headache. This type of headache can cause mild or moderate pain in the head, neck, and behind the eyes. Some patients say that a tension headache feels like a tight band around their foreheads.The majority of people who suffer from tension headaches have episodic headaches, which occur (on average) one or two times per month.ome patients say that a tension headache feels like a tight band around their foreheads.

Stems The stem is the major aerial support system in most plants. Sometimes called a stalk or trunk, it holds up the plant into the air and provides a pathway for fluid transport between the shoot and the root. The stem also may represent a huge volume for storage of materials.

Plant Structures Terms. The parts of the plant are divided into two basic sections, the root and the shoot. The root is comprised of all the structures below the soil, and the shoot is composed of the structures above.Included in the shoot of seed plants are the stem, the leaves, and the seeds.Additionally, angiosperms contain flowers as part of their shoots.erms.

Mycorrhizae fungus invades whole cortex, and forms highly branched haustoria called arbuscules, plus spherical storage structures called vesicles. fungus penetrates only outer few layers of root cortex, and hyphae remain intercellular. Forms thick mantle-like sheath around root, which stunts root growth.

Cell cortex Cell cortex. The cell cortex, also known as the actin cortex or actomyosin cortex, is a specialized layer of cytoplasmic protein on the inner face of the plasma membrane of the cell periphery. It functions as a modulator of plasma membrane behavior and cell surface properties.

- For other uses, see Cortex (disambiguation) . The renal cortex is the outer portion of the kidney between the renal capsule and the renal medulla. In the adult, it forms a continuous smooth outer zone with a number of projections (cortical columns) that extend down between the pyramids.t contains the renal corpuscles and the renal tubules except for parts of the loop of Henle which descend into the renal medulla. It also contains blood vessels and cortical collecting ducts. The renal cortex is the part of the kidney where ultrafiltration occurs.

- Tissue that is on the inside of the vascular tissue ring is called pith, and tissue on the outside of the vascular tissue is called cortex. Ground tissue is made up of three main cell types: Parenchyma cells are the most common cells you encounter inside a plant.issues that make up part of the plant but are not vascular tissue or epidermis are called ground tissue. Ground tissue can be found inside and outside the ring of vascular tissue in the plant stem.

- Parenchyma (Para-beside, enchyma-In poured) Parenchyma is the fundamental tissue of the plant body. It is found in every part of the plant body like pith and cortex of stem and root, mesophyll of leaves, flesh of fruits, floral parts and even in xylem and Phloem. Cells have thin primary walls and polyhedral shapes.
