Last week we surveyed the remarkable diversity within the
plant world, and looked at the ways plants are named and classified. This week we’ll
build on last week’s work by exploring how and why these diverse forms arose.
We’ll revisit the topic of plant basic needs, and look at the evolutionary process
that gave rise to adaptations that allow plants to fill their needs in challenging
environments. We’ll move on to adaptations for protection, and, finally, discuss
adaptations to climate. Although the distinctions are often blurry—for example,
climate influences a plant’s ability to fill its basic needs—this organization
will give us a frame of reference and a place to start. |
