Question

What adaptions of plants and flowers can be used to make a dichotomous of four species ?

Answer 1

depends which 4 species you are supposed to make the dichotomous key from but some good starting points could be:

flowers, no flowers

woody stem, not woody stem

broad leaves, not broad leaves

over 1m, below 1m in height

fruit, no fruit

asexually reproduces, does not asexually reproduce

For a dichotomous key opposites are not technically correct as ways to split up your species. (example broad leaves, narrow leaves) would not be correct
