A fax number is nothing but a  telephone number that has a fax machine conâ¦nected to it. Of course,  if you receive more than an occasional fax, you will probably want  a separate line for the fax machine; contact your local telephone  company to find out about getting an additional line.
Vascular plants (from Latin vasculum: duct), also known as tracheophytes (from the equivalent Greek term trachea) and also higher plants, form a large group of plants that are defined as those land plants that have lignified tissues (the xylem) for conducting water and minerals throughout the plant. In vascular plants, the principal generation phase is the sporophyte, which is usually diploid with two sets of chromosomes per cell. 2  Only the germ cells and gametophytes are haploid.
Vascular Plants. The plant world is conveniently separated into two major groups: nonvascular plants and vascular plants. The nonvascular plants include the bryophytes, while the vascular plants include the ferns, gymnosperms, and angiosperms (see Chapter 19). The nonvascular plants have no internal transport system.
