Root morphology is the study of the physical characteristics and structures of plant roots, including their shape, size, branching patterns, and adaptations. This research area focuses on understanding how root morphology influences a plant's ability to acquire water, nutrients, and support from the soil. Root morphology can also impact a plant's ability to compete with other plants for resources, resist environmental stresses, and interact with soil microbes. Researchers in this field use a variety of techniques, such as microscopy, imaging, and modeling, to study root morphology and its role in plant growth and development.
