Consider the nonflowering plant growing along the wall that is pictured below.
what type of plant is this?
a angiosperm
b bryophyte
c seed
d gymnosperm

The correct answer is option B, that is, bryophytes.  

In the given picture, it is clear that the plants belong to one of the classes of bryophytes known as moss. Mosses are small flowerless plants, which generally develops in dense green mats or clumps, usually in shady or damp locations.  

The individual plants are typically one cell in thickness, combined with a stem that may be unbranched or branched and possess only a restricted function in conducting nutrients and water. Though some species exhibit conducting tissues, which are usually poorly developed and structurally distinct from identical tissue found in vascular plants.
