PLEASE PROVIDE A TABLE OF DIFFERENCES BETWEEN PARENCHYMA, SCLERENCHYMA AND COLLENCHYMA.
Very thin cell wall.
Unevenly thickened cell wall.
Thick cell wall.
The cells are loosely packed.
Little space between cells.
No intercellular spaces present, cells are tightly packed.
The cell wall is made up of cellulose.
The cell wall is made up of hemicelluloses and pectin.
The cell wall is made up lignin.
Most of the plant tissues are made up of parenchyma cells.
Collenchymas cells make up the epidermal layers.
The outer woody stem portion of large trees is made up of sclerenchyma cells.
Cells are living.
Cells are living.
Matured cells are dead.
Sorry but i was not able to find it in the tabular form..
Parenchyma- most abundant cell type in plants (e.g. cells making up the fundamental ground tissues; usually unspecialized; characteristics include:living at maturity with a very thincell walllarge vacuole for storage and sequestering of materialslarge amount of intracellular spacesphericalrelatively regular shapevery elastic (can change shape and then return to original shape with little deformation)Functions ofparenchyma cellsinclude:photosynthesisstoragesecretionCollenchyma - found just below the epidermis in petiole (e.g. celery stalks), leaves, and young stems; usually specialized; characteristics include:living at maturityirregularly thickened cell walls (+cellulose)prism shapedplastic (can change shape but do not usually return to the original shape; remain deformed)Functions of collenchyma cells include:supportsome involvement in transport of nutrientsSclerenchyma - in mature parts of the plant, especially in woody plants and herbaceous perennials; specialized; characteristics include:dead at maturity - protoplast is absentvery thick, sclerified cell wall (+lignin)impermeable to water and other nutrientsin cells specialized for transport of water and nutrients, the cell wall contains holes called pits.Functions include:supportprotectiontransport of water and nutrientsSpecific examples of sclerenchyma cells:fibers - long and slendersclerids (stone cells) - relatively spherical; the gritty texture of pears is due to the presence of stone cells.
