WHAT IS INTUSSUSCEPTION AND APPOPOSITION?
what is richmond lang effect?
distinguish between polysepalous and gamosepalous calyx
required for growth
(1) Oxygen provides the medium for enzymatic
activities needed for growth
(2) Water helps in releasing metabolic energy
essential for growth activities
(3) Turgidity of cells help in extension growth
(4) Only microelements are required by plants for
the synthesis of protoplasm and act as source
of energy
why are auxins present in human urine??
a)10-15 %
b)85-90%
