Plant anatomy is the study of the shape, structure, and size of plants. As a part of botany (the study of plants), plant anatomy focuses on the structural or body parts and systems that make up a plant. A typical plant body consists of three major vegetative organs: the root, the stem, and the leaf, as well as a set of reproductive parts that include flowers, fruits, and seeds.

As a living thing, all of a plant’s parts are made up of cells. Although plant cells have a flexible membrane-like animal cell, a plant cell also has a strong wall made of cellulose that gives it a rigid shape. Unlike animal cells, plant cells also have chloroplasts that capture the Sun’s light energy and convert it into food for itself. Like any complex living thing, a plant organizes a group of specialized cells into what are called tissues that perform a specific function. For example, plants, therefore, have epidermal tissue that forms a protective layer on its surface. They also have parenchyma tissue usually used to store energy. The “veins” or pipeline of a plant are made up of vascular tissue that distributes water, minerals, and nutrients throughout the plant. Combined tissues form organs that play an even more complex role.
