Plants contain numerous types of cells and tissues. In this lesson, you will learn about the function of a type of cell known as parenchyma that is commonly found in plants.
•Definition of Parenchyma
Plants have numerous types of specialized cells that are specifically designed to carry out life functions. The word 'parenchyma' just means the bulk of a thing, but in plants specifically, parenchyma cells are thin-walled cells that make up the inside of many non-woody plant structures including stems, roots, and leaves.
Parenchyma forms the cortex (or main filling) of stems, the inner layer of cells within a leaf, the endosperm material that feeds a growing seed, and the pulp of a fruit.
•Function of Parenchyma in Plants
Parenchyma cells can serve many functions. Their role is largely based on their location in the plant; that can determine whether they will serve in storage, photosynthesis, or damage repair.
Parenchyma cells have large central vacuoles, which are large, membrane-enclosed organelles found in many plant cells. These vacuoles are able to be used by plant cells to store materials and to maintain optimal pressure within the cell of the plant.
hope this will help uh

➧ Types 0f Simple Permanent Tissues are:-▬▬▬▬▬▬▬▬▬▬▬▬▬⤵
❶❭ Parenchyma:-┅┅┉┅┅┉┅┅┉┅┅┉┅┅┉┅☟
● The unspecialised living plant tissue formed of thin walled rounded cell.
● This cell are isodiametric & least specialised.
● It is considered at the fundamental tissue or ground tissue.
➧ It's Characteristics are:-━━━━━━━━━━━━━━━━━━☟
❱ Cells are living cells with thin cell wall of cellulose.
❱ They are rounded, oval or polygonal in shape with intercellular spaces.
❱ Cytoplasm is dense with one large or more than one small vehicles.
➧ It's Functions are:-━━━━━━━━━━━━━━━━━━☟
❱ It form the ground tissue or packing tissue in plants.
❱ It provide rigidity to the plant by keeping cell rigid.
❱ It's cell store food.
❱ It helps in wound healing, regeneration & grafting.
❱ It cells are allow to exchange of respiratory gases.
❷❭ Collenchyma:- ┅┅┉┅┅┉┅┅┉┅┅┉┅┅┉┅☟
● It is found in steam leaf, leaf stalk & leave midribs of dicot herbaceous plant.
● It forms a layer below the epidermis called hypodermis.
● It is absent in monocot stem.
➧ It's Characteristics are:-━━━━━━━━━━━━━━━━━━☟
❱ Cells are living unfairly elongated.
❱ They appear polygonal, 0val or circular in cross-section.
❱ Cells surrounded by thik primary cell wall alone.
❱ The cell wall is thickened along the corner due to the deposition of cellulose & pectin.
❱ The cytoplasm has a large central vacuole.
➧ It's Functions are:-━━━━━━━━━━━━━━━━━━☟
❱ It provide mechanical support to the delicate developing organs of herbaceous Dicot stem.
❱ It cells combine both tensile strength & flexibility.
❱ It cells with chloroplast carrying out photosynthesis.
❱ This cell also store food & allow growth & elongation of 0rgan.
❸❭ Scelerenchyma :- ┅┅┉┅┅┉┅┅┉┅┅┉┅┅┉┅☟
● It is a hard supporting tissue formed of long, narrow & pointed ends.
● It occurs in root stem, leaves & petiole.
● These cells are dead with thick lignified walls that gradually lose Protoplasm.
➧ It's Characteristics are:-━━━━━━━━━━━━━━━━━━☟
❱ These are dead cell without nucleus & cytoplasm.
❱ Their cell wall is formed of cellulose & hemi-cellulose.
❱ It is thickened due to the secondary the position of Lignin.
❱ Lignin act as a cement & hardens the cell wall.
❱ The lignified cell wall has pits.
➧ It's Functions are:-━━━━━━━━━━━━━━━━━━☟
❱ It provide most of the support in a plant.
❱ To compressive & tensile stresses in plants.
❱ It allows the organs to withstand bending, shearing & compression.
❱ It's cells provide protective, vascular & supportive functions.
