Question

Which of the choices are examples of convergent evolution? Select all that apply. the vascular cambium of quillworts (Isoetes) and that of angiosperms the cuticle of bryophytes and that of gymnosperms the roots of bryophytes and those of lycophytes the water-conducting tissues of some bryophytes and that of ferns

Answer 1

Examples of convergent evolution are:

The vascular cambium of quillworts (Isoetes) and that of angiosperms.

The water-conducting tissues of some bryophytes and that of ferns

Step-by-step explanation:

Vascular cambium is the primary growth tissue in stems and roots of the plants.

quill wort is a primitive plant. Theses have no true stems, leaves or roots. The roots of angiosperms have vascular cambium. The formation of lignin is done by vascular cambium. The distinct biochemical processes in which lignin is synthesized in both quill wort and angiosperm though they are 400 million apart is an example of convergent evolution.

Bryophytes have well-developed water conducting specialized tissues for the even distribution of water and nutrients to the parts of plant. Ferns are tracheophytes or vascular plants. Bryophytes have evolved before tracheophytes. They do not have vascular tissue and they support themselves because of the turgor pressure in the cell.

Thus, bryophytes support themselves by turgor pressure in their cells and are small in height while tracheophytes perform this function by vascular tissue which have evolved over the time.
