of the pitcher is closed by a lid which is the modification of leaf apex. VII. Bladder In bladderwort ( Utricularia ), a rootless free- floating or slightly submerged plant common in many water bodies, the leaf is very much segmented. Some of these segments are modified to form bladder-like structures, with a trap-door entrance that traps aquatic animalcules.
VIII Floral leaves Floral parts such as sepals, petals, stamens and carpels are modified leaves. Sepals and petals are leafy. They are protective in function and considered non-essential reproductive parts. Petals are usually coloured which attract the insects for pollination.
Stamens are considered pollen bearing microsporophylls and carpels are ovule bearing megasporophylls. . . Leaf duration Leaves may stay and function for few days to many years, largely determined by the adaptations to climatic conditions.

Compare sympodial branching with monopodial branching. . Differentiate pinnate unicostate with palmate multicostate venation Leaves possess vascular tissues in the form of veins which render support to the lamina and help in transport of water, nutrients and food in and out of leaves. Phyllotaxy is the arrangement or distribution of leaves
