Four examples of plant life are mosses, ferns, conifers and flowering plants. The main differences are in how they reproduce. The oldest forms of plants require water to germinate, while the newer ones can reproduce on dry land.Continue Reading
Mosses are bryophytes. They are land plants but have spores instead of seeds. Since these plants have no vascular system, they are small in size and must live in moist environments. Mosses depend on wind to distribute spores to a moist growing spot.
Ferns are pteridophytes. They have vascular systems that transports water and nutrients throughout the plants and grow considerably taller than mosses. Ferns also use spores to reproduce, usually found on the underside of mature leaves, or fronds.
Conifers are gymnosperms, and include large trees such as the redwoods and Douglas firs. Conifers produce pollen, which is picked up by the wind and onto the female cones. When pollinated, the cones produce seeds, which could be distributed by the wind or by animal predation.
The angiosperms, or flowering plants, are the newest forms of plant evolution. Flowers attract insects and birds with their bright colors and sweet scents. This makes pollination more effective because these creatures will move from bloom to bloom picking up and distributing pollen.
The pollinated flower produces seeds within an ovary, which becomes a fruit. Foragers eat the fruit and deposit the seeds elsewhere. Seeds may also be dispersed by sticking to the fur of animals and later dropping off, or by the wind.Learn more about Botany
