Answer: There are various ways by which the stem of the plants can modify itself in order to adapt into the environment.
Explanation:
Stem of some plants forms the symbiotic relationship with the fungi in order to obtain more nutrition and water from the soil. This allows the plant to live in scarcity of water and nutrient because they have some adaption for such conditions.
Most of the plants like legumes have symbiotic association with the bacteria that helps in the nitrogen fixation.
Some of the plants have root hairs extended upto kilometers so that they can get water from the ground even if it has a very low level.
The roots of the mangrove plants are equipped to tolerate saline conditions. This is also a great help to the plant growing in such environment.
