The study of the internal structure of plants is called anatomy. Plant anatomy is the branch of botany that focuses on examining the internal organization and structure of plant tissues and cells. This study provides insights into how plants function, grow, and develop. Plant anatomists investigate various plant structures, including roots, stems, leaves, and reproductive organs, at both the macroscopic and microscopic levels. By understanding the arrangement and function of different plant cells and tissues, researchers can gain knowledge about how plants transport nutrients, photosynthesize, and reproduce. Plant anatomy also aids in identifying species and understanding evolutionary relationships among plants. This field of study is essential for advances in plant breeding, agriculture, and horticulture, as it helps improve crop varieties and supports sustainable practices in plant cultivation and management.
