(See Figure 200.) In spite of their delicate leaves, mosses are able to live in dry places. Clumps of moss hold water even better than a sponge. Even if mosses do become dried out, they are usually able to recuperate when they become moist again. The dead brown parts of moss.

(The word means root-like.) The rhizoids serve as holdfasts, and probably absorb moisture. (See Fig- ure 201.) A. Reproduction. — Perhaps you have seen what is sometimes called moss fruit. It grows up from the top of the leafy stems. (See Figure 202.) Sometimes all the moss plants in a clump appear to be bearing these structures at the same time.
