Exploring the Roots and Stems of Ant Plant:
Anatomy and Function

Updated: April 19, 2023

Ant plants, also known as myrmecophytes, are plants that have evolved to provide homes and food for ants. They have a complex structure that allows them to house and feed these tiny insects.

In this article, we will explore the anatomy and function of the roots and stems of ant plants.

The Roots of Ant Plants

The roots of ant plants play a critical role in providing a home for ants. They have evolved to form hollow chambers that can house ant colonies. These chambers are made up of specialized cells that provide a secure environment for the ants to live in.

The roots also secrete nectar, which provides food for the ants. This nectar is produced by specialized glands called extrafloral nectaries, which are found on the roots and stems of the plant.

In some ant plants, such as the bullhorn acacia (Acacia cornigera), the roots also produce large thorns. These thorns provide additional protection for the ants living in the chambers.

The Stems of Ant Plants

The stems of ant plants also play an important role in providing a home for ants. In some species, such as the Amazonian ant-plant (Hirtella physophora), the stems have evolved to form large hollow cavities that can house entire ant colonies.

The stems also secrete nectar through extrafloral nectaries, just like the roots. This nectar provides food for the ants living in the cavities.

In addition to providing a home and food for ants, the stems of ant plants also serve as a means of defense against herbivores. Some ant plants, such as the Acacia species, have evolved to produce large thorns on their stems that deter herbivores from eating their leaves.

FAQ

Q: What is an ant plant?

A: An ant plant is a plant that has evolved to provide homes and food for ants.

Q: How do ant plants provide homes for ants?

A: Ant plants have evolved specialized structures, such as hollow chambers in their roots and stems, that can house entire ant colonies.

Q: Why do ant plants provide homes and food for ants?

A: Ants are beneficial to ant plants because they provide protection against herbivores and help to disperse their seeds.

Q: What is extrafloral nectar?

A: Extrafloral nectar is nectar that is produced by glands on a plant’s stems or leaves. It is not produced in flowers like normal nectar, but instead serves as a food source for insects such as ants.

Q: Do all ant plants produce thorns?

A: No, not all ant plants produce thorns. Thorns are only found in certain species, such as Acacia cornigera.

In conclusion, the roots and stems of ant plants have evolved to provide homes and food for ants. These structures serve as a means of defense against herbivores and are critical to the survival of both the plant and the ant colony living within it.
