In the spring, you pass by a rocky outcrop dripping with water and covered with a carpet of short green plants. In the summer, you notice that water is no longer dripping off the rock, and the plants appear brittle and dry. In the fall, the rock is again wet, and the plants now appear soft and green.
These plants are most likely:
a. angiosperms.
b. bryophytes.
c. gymnosperms.
d. lycophytes.
e. algae.
