Answer 2

In BRYOPHYLLUM, small plants grow at the edge of leaves.

Explanation:

BRYOPHYLLUM reproduces by the process of VEGETATIVE PROPAGATION. The leaves of this plant have special buds that are present at the margins. These buds grow to form new plants and after growth they get detached from the leaves and are capable of growing into a new individual plant once it touches the soil. The buds are called EPIPHYLLOUS BUDS (which do not originates from stem apex or axil of leaf).
