Hint: Analogous means related or comparable to something else either in general or in some specific detail. They are structures, such as organs or parts of plants; those are very like in two unrelated organisms.

Complete answer:
Analogous organs are those that are different in their origin and structures but execute a similar function in two dissimilar species. The account in favor of convergent evolution. The examples of analogous organs in plants are:

1. Potato is a stem while the sweet potato is a root; both carryout storage and vegetative propagation.

2. Cactus and Euphorbia go to two different species but both have a photosynthetic stem and leaves reduced to spines.

3. Pyracantha (firethorn) and Berberis (barberry) both have thorns for defense but in the firethorn plant, the thorns are customized stems while in barberry the thorns are modified leaves.

Additional information:
The analogous organs in plants are foliage of opuntia and peepal. In opuntia, the modified stem is a wide succulent leaf-like structure that performs photosynthesis.
One of the common plants is Peepal that performs the process of photosynthesis. So both perform the same function that is why they can be called analogous.

Note: Evolutionary convergence including random creatures living in comparative conditions however in places (allopatry) can likewise happen in another way. This normally happens in moderately basic networks in which biotic corporations are exceptionally unsurprising and the subsequent number of various methods of misusing the earth is restricted.
Under unusual conditions, the process of convergence takes place in which success forces for the particular mode of existence are particularly strong.
