Choose the correct statements
i. Cladoctes are variation of phylloclades with limited growth
ii. Phyllodes and phylloclades are analogous organs
iii. Off sets are sub aerial stem modification of limited growth 
iv. Bulbils are acrial stem modification for storage and vegetative propagation

     Cladoctes and phylloclades are stem modifications to perform photosynthesis , the difference is        incase of cladodes one to two internodal length of stem modifies to perform photosynthesis , but       in phylloclades entire stem modifies to perform photosynthesis .

         Phyllodes and phylloclades are analogous organs . They performs same function that is                 photosynthesis . Phyllode is leaf modification , phylloclade is stem modification .

        Offsets are sub aerial stem modification of limited growth . It bears a rosette leaves at each node        and a tuft of balancing roots arising from the base of the discoid stem.

         Bulbils are arial stem modification for storage and vegetative propagation.

         Vegetative bud modifies into bulbil in Dioscoria and floral bud modifies into      

          Bulbil in Agave.
