A key to bryophytes and pteridophytes

A school garden has six small plants with labels. You will write a key that sorts each one into its group, list the bryophytes, and count the plants that bear cones.

The idea. A plant with vascular tissue is a pteridophyte; a plant without it is a bryophyte. Some pteridophytes carry their sporophylls in cones (strobili).

Your tasks.

1. In group, return "pteridophyte" if the plant has vascular tissue, and "bryophyte" if it has none.
2. Set bryophytes to a list of the names of the bryophytes, in the order of the table.
3. Set cones to the number of plants whose spore organs are in a cone.
