GENERAL HISTOLOGY

Detailed explanation-1: -Parenchyma cells are the foundation of a plant as reproductive cells (spores, gametes) are parenchymatous in nature. Single parenchyma cell of a zygote has an ability to develop into an entire plant. These cells are called “totipotent” cells.

Detailed explanation-2: -Meristems produce cells that quickly differentiate, or specialize, and become permanent tissue. Such cells take on specific roles and lose their ability to divide further. They differentiate into three main tissue types: dermal, vascular, and ground tissue.

Detailed explanation-3: -Parenchyma is one of the three main types of ground, or fundamental, tissue in plants, together with sclerenchyma (dead support tissues with thick walls) and collenchyma (living support tissues with irregular walls).

Detailed explanation-4: -Parenchyma forms the bulk of plant ground tissue, where they may be specialised to function in photosynthesis, storage, or transport. Parenchyma is integral to vascular tissue, where it provides a route of exchange for materials within and between the xylem and the phloem.

Detailed explanation-5: -tissues are dermal, vascular, and ground tissues. Primary dermal tissues, called epidermis, make up the outer layer of all plant organs (e.g., stems, roots, leaves, flowers). They help deter excess water loss and invasion by insects and microorganisms.
