If you find a plant growing in a shady spot, how can you tell whether it is a simple plant?

• Observe its size and how it is growing.

• If it is a mat of closely packed small plants with small rootlike structures, then it is likely to be a simple plant.

• Look for tubes in the leaves--if tubes are not present, then it is probably a simple plant.

• All of the above answers are correct.
