EVERYDAY SCIENCE

Detailed explanation-1: -It contains cells that can divide and give rise to lateral roots. Another type of ground tissue, called pith, can be found in the center of monocot roots. It is composed of parenchyma.

Detailed explanation-2: -Pith. Located in the middle of monocot roots, the pith (or medulla) is composed of soft, spongy parenchyma cells with spaces between them. The pith is surrounded by a ring of vascular bundles, containing xylem and phloem.

Detailed explanation-3: -The innermost region of the plant stem consists of a spongy tissue called pith, which is composed of parenchyma cells. The main function of the pith is to store essential nutrients like water and sugars, which can be transported between the pith and the vascular bundles.

Detailed explanation-4: -In monocots, the primary root is short lived. It is replaced by a large number of roots which originate from the base of the stem. These roots constitute the fibrous root system.

Detailed explanation-5: -Root systems are mainly of two types (Figure 1). Dicots have a tap root system, while monocots have a fibrous root system. A tap root system has a main root that grows down vertically, and from which many smaller lateral roots arise.
