Nonflowering Plants
Follow
the progression of nonflowering plants from life in the sea to life on land in
this unique survey. Vivid re-creations of the environments in which these plants
evolved change before your eyes. Detailed illustrations show land adaptations in
the three groups of nonflowering plants: the nonvascular plants, the seedless
vascular plants, and the seed-bearing vascular plants. Beautiful photographs and
plant descriptions teach students characteristic differences used to identify
the nonflowering plants, from the often-overlooked hornworts to the bizarre
Welwitschia to the more familiar ferns and pines. Students will discover the
value of nonflowering plants as they learn of their importance, past and
present.
