Mr. diaz asked his students to develop a dichotomous key to classify vascular land plants. marynell and sarah were given the pictures seen here. their first step in developing the key was to choose one broad category to use in separating this plant from others. one way would be to separate plants as
a) having xylem or phloem.
b) having leaves or having needles.
c) having woody tissue or non-woody tissue.
d) being wind pollinated versus insect pollinated.

The correct answer would be B) having leaves or having needles.

Dichotomous key refers to the tool designed by scientists which helps in the identification of an organism such as trees, mammals, reptiles et cetera.

The key consists of a series of clues or statements which help the user to identify an organism.

For example, one of the statement would be the presence of needles or leaves in a plant.

when a previously occupied environment was disturbed that kills much of all its

community
