Simple Permanent Tissues➫ Tissue which is made up of similar permanent cells that carry out the same function.
➧ 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.

☀There are 3 types of Simple Permanent Tissue :-
▶Parenchyma :-
➡Characterstics -
✔They form basic packing tissue.
✔Cells of this tissue are relatively unspecialised and may be oval, rounded or elongated in shape.
✔Cell walls are highly thickened due to lignin deposition.
▶Collenchyma :-
➡Characterstics -
✔Collenchyma cells mainly form supporting tissue and have irregular cell walls.
✔They are found mainly in the cortex of stems and in leaves.
▶Scelerenchyma :-
➡Characterstics -
✔Sclerenchyma is a plant tissue providing mechanical stiffness and strength.
✔Fibres and sclereids are the main types of sclerenchyma cells.
✔Most sclerenchyma cells show intrusive growth.
✔The cell walls of sclerenchyma have thickened secondary layers made from cellulose, hemicelluloses and lignin.
Thanks.
