Question

write the properties and function of parenchyma collenchyma and sclerenchyma tissues​

Answer 1

FUNCTIONS-:

$Parenchyma$$cells$$help$$in$$storage$$of$$foods, in$$gaseous$$exchange, and$$in$$photosynthesis.$

$Sclerenchyma$$cells$$provide$$mechanical$$support$$to$$the$$plant.$$It$$also$$supports$$transportation$$of$$water$$and$$nutrients$$to$$the$$plants.$

PROPERTIES-:

parenchyma collenchyma~

$1)They$$form$$basic$$packing$$tissue.$

$2)Cells$$of$$this$$tissue$$are$$relatively$$unspecialised$$and$$may$$be$$oval, rounded$$or$$elongated$$in$$shape.$

$3)Their$$cell$$walls$$are$$thin.$

$4)These$$cells$$are$$living$$and$$show$$large$$intercellular$$spaces.$

$5)Cytoplasm$$is$$dense$$with$$a$$small$$nucleus.$

sclerenchyma tissues~

$1)Sclerenchyma$$cells$$have$$thick, lignified$$secondary$$walls, lack$$cell$$contents$$at$$maturity, and$$occur$$throughout$$all$$plant$$tissues.$

$2) These$$features$$make$$sclerenchyma$$tissues$$hard, rigid, and$$somewhat$$brittle.$

$3)  Sclerenchyma$$cells$$can$$occur$$as$$aggregates$$within$$ground$$tissue (sclereids$$or$$stone$$cells$$or$$as$$elongated$$fibers).$
