Final answer:
Offspring growing from the stem or root of a plant is a type of asexual reproduction known as vegetative reproduction. It includes rooting from cuttings, rhizomes, tubers, and stolons, among other methods. Bryophyllum is an example of a plant that reproduces vegetatively from its leaves.
Step-by-step explanation:
The form of reproduction where the offspring grow specifically from the stem or root of a plant is known as vegetative reproduction, which is a type of asexual reproduction. This method includes various natural methods such as rooting from stem cuttings, where a stem is cut and placed in moist soil to sprout roots, or from parts of roots, which are induced to produce new shoots. Plants can also reproduce asexually through structures like rhizomes, tubers, and stolons. For instance, ginger creates new plants from rhizomes, potatoes from tubers, and strawberry plants from stolons. An example of vegetative reproduction from the leaves is seen in plants like Bryophyllum, where new plants can develop directly from the margins of the leaves.
