The sporophyte of <u>whisk ferns</u> consists of evenly forking photosynthetic stems that lack roots and leaves.
Whisk ferns are the elementary and simplest vascular plants.
They contain small-sized protuberances which are called ' enations.'
In these plants, a vascular system is present in the center through which the transport of nutrients and other fluids takes place.
Moreover, roots and leaves are absent in these plants and are composed of forklike stems.
To put it simply, these plants have hair-like structures that are part of the rhizomes. These structures are called rhizoids.
