Yes, fruit is considered an organ in plants.
A fruit develops from the flower's ovary after fertilization, containing the seeds. It plays a crucial role in protecting the seeds and aiding in their dispersal.
While the fruit itself is an organ, it's important to understand that it's not a single, simple organ like a leaf or a stem. Instead, it comprises various tissues and structures.
For example, the outer layer of the fruit is called the exocarp, while the inner layer protecting the seeds is known as the endocarp. The fleshy part between them is the mesocarp.
The reference mentioned that fruit consists of a mature ovary with additional parts from other floral structures like the receptacle, calyx, and bracts. These parts contribute to the overall structure and function of the fruit.
