Leaves with different functions

1. Leaf tendril
In some plants the entire leaf is modified into tendril e.g. In Lathyrus aphaca (janglimatar) where entire leaf is modified into tendril and photosynthesis is performed by stipules.

2. Leaf spines
In prickly Pear and Barberry, leaves are reduced to spines to reduce transpiration.

3. Leaf roots
In salvinia (ferns) leaves are modified roots to absorb and act as balances.

4. Scale-leaves
These are thin, dry stalkless structures which protect axillary buds. Sometimes they are fleshy as in onion. They are commonly seen in parasites, saprophytes and underground stems.

5. Phyllodes
Discussed earlier in Acacia.

6. Pitcher
Plants growing in nitrogen deficient soils bear their leaf blades, petiole modified into pitchers to capture and digest insects. Such plants are called insectivorous e.g. Nepenthes.

7. Bladder
In utricularia segmente d leaves are modified into bladder like structures for trapping the insects.
