Some plant species exhibit maternal care behaviors, where the parent plant provides nutrients and protection to their offspring. For example, the seeds of some species are encased in a fleshy fruit, offering nourishment and protection until the seedlings can establish themselves.

Many lifesaving drugs, such as aspirin (originating from willow bark) and quinine (derived from the cinchona tree), have plant origins. Plants have played a crucial role in both traditional medicine and modern pharmaceuticals, providing valuable compounds for human health and well-being. This underscores the importance of preserving plant diversity.
