This fruit ripens and falls from the stem. It drifts about over the bottom, and later it germinates. At the apex of the ovary is a little crown of cells, between which lies the passageway for the entrance of Colorphylless Plants 139 the sperm cell at the time of fertilization. This crown is composed of five cells in Chara ; of ten cells in Nitella. It is deciduous in Chara ; it is persistent in Nitella. The stoneworts, unlike many other algae, are wonder- ftilly constant in their localities and... distribution, and regular in their season of fruiting. They cover the same hard bottoms with the same sort of gray-green meadows, year after year, and although little eaten by aquatic animals, they contribute important shelter for them, and they furnish admirable support for many lesser epiphytes. CHLOROPHYLLESS WATER PLANTS, BACTERIA AND FUNGI Nature's great agencies for the dissolution of dead organic materials, in water as on land, are the plants that lack chlorophyl. They mostly reproduce by means of spores that are excessively minute and abund- ant, and that are distributed by wind or water every- where; consequently they are the most ubiquitous of organisms.
