Pith is composed of soft, spongy parenchyma cells, which store and transport nutrients throughout the plant. In eudicots, pith is located in the center of the stem. In monocots, it extends also into flowering stems and roots. The monocot root is composed of an epidermis, cortex, endodermis, pericycle, xylem, phloem and a pith. Unlike dicot roots , a monocot root has a pith in the stele. It also contains vascular bundles that are composed of both xylem and phloem.

The pith is made up of polygonal oval or rounded parenchyma cells which enclose intercellular spaces. The pith cells store food. In some dicots, the central part of the pith disintegrates to produce a cavity , called pith cavity , e. Compared to stems, roots have lots of cortex and little pith. Both regions include cells that store photosynthetic products. The cortex is between the epidermis and the vascular tissue, whereas the pith lies between the vascular tissue and the center of the root.

Is Onion a monocot or dicot? Legumes pea, beans, lentils, peanuts daisies, mint, lettuce, tomato and oak are examples of dicots. Grains, wheat, corn, rice, millet lilies, daffodils, sugarcane, banana, palm, ginger, onions, bamboo, sugar, cone, palm tree, banana tree, and grass are examples of plants that are monocots. What is the difference between pith and cortex? Both the cortex and pith are composed mainly of parenchyma cells.

Support is given to the stem by collenchyma cells which may occur just under the epidermis in the cortex. How can you distinguish the roots of monocot and dicot plants? The root of the plant that has single cotyledon in its seed is known as monocot root. Dicot root is narrow and has a tap root-like structure.

Monocot root is comparatively wider and has fibrous root-like structure. Dicot root has fewer numbers of xylem and phloem, i. Is Grass a monocot or dicot? Grass is a monocot. The reduction of xylem height results in the separation by the intrusion of fusiform initials into rays.

The pith can be used as a food source for the segregation starch content. The sago palm pith can be used for the extraction of starch. The extraction is a simple process; however, it is highly toxic in raw form and leaching of toxins is required. The remaining pith is rich in starch and requires further processing.

Papyrus is the ancient writing material like the thick paper made from the pith of the papyrus plant. The stem of the papyrus plant is cut and the outer layer or ring is removed. Afterward, the long pithy inner side of the stem is cut longitudinally to cut pieces. The pieces are put side by side on a hard surface and then the pieces are soaked in water for a long time.

Then the two layers were glued together, and the moist layer was hammered together to result in thick paper. The paper is then dried and polished at the end. The sheets of the papyrus were then rolled on some rounded object and reasonably sized sheets were cut. Stems primarily provide plants structural support. This tutorial includes lectures on the external form of a woody twig and the origin and development of stems.

The different types of plant tissues are meristematic, simple, secretory, and complex tissues.
