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.
