  2. In Eichhornia, the petioles expand becomes green and synthesise food.
  3. Opposite phyllotaxy is seen in guava.

  • I and II

  • I and III

  • II and III

  • I, II and III

Solution

B.

I and III

Most of the leaves have a swollen leaf base known as pulvinus. Its attachment to the stem is not strong. In guava opposite phyllotaxy is found. In this case, all the pairs of leaves of branch arise in the same plane so that two vertical rows are formed.

In Australian Acacia, petiole gets modified into leaf-like structure and synthesise food. In Eichhornia, petiole becomes spongy and helps in floating.
