... of over 25,000 species throughout the world. Bryophytes are made up of three major groups of plants: the mosses, liverworts, and hornworts, all of which are located throughout the world, even in extreme environments ( Raven 1999). Bryophytes are usually small in size, and most of the members of the phylum are dependant on water or moist surroundings to survive(Raven 1999). The ... is unsure if this has a negative effect on organisms that then rely on the bryophytes, but research is being suggested that would use certain species of mosses to monitor regional levels of atmospheric metals(...

... elevation in Nepal of 500-2700m has a warm climate; between 2700-3000m there is a cool climate; between 3500-4100m the summers are cool and winters are very cold, areas above 4100m are controlled by a severely cold climate. In contrast New Zealand's north has the warmest climate; the ... is forest; the Tarai has extensive hardwood and bamboo forests. On the lower slopes of mountains, pines, oaks and wild flowers grow; firs and shrubs grow in much higher locations, this includes the tree rhododendron, Nepal's national flower. Mosses and grasses grow at altitudes of 3700m and above, but at...

... hundreds to thousands of types of plants existed during the Mesozoic Era. Many of these plants had edible leaves, including evergreen conifers (pine trees, redwoods, and their relatives), ferns, mosses, horsetail rushes, cycads, ginkos, and in the latter part of the dinosaur age flowering (fruiting) plants. Although the exact time of origin for flowering plants is still uncertain, the last ... of the dinosaurs certainly had fruit available to eat. Dinosaurs probably communicated both vocally and visually. The chambered headcrests on some dinosaurs such as Corythosaurus and Parasaurolophu...

... very big. Plants with vascular tissue, on the other hand, can grow bigger and thicker because each cell gets water and nutrients through the vascular tissue. Types of Seedless Vascular Plants Seedless vascular plants include the club mosses, spike mosses, horsetails, and ferns. Today, there are about 1000 species of club mosses, spike mosses, and horsetails. Ferns are more abundant, with at last 12 000 species known. During the Paleozoic ... cells that unite to form the zygote. The zygote develops into the embryo, then sporophyte, as in the mosses. But in ferns, the gametophyte also pro...

... zone has the highest plant diversity of any zone. There are thousands of species of trees, up to few hundred even in very restricted areas. Gymnosperms are rare, except cycads. Ferns and monocots are very diverse, many of them with tree form. Many of the tree species are in large families that are entirely or largely restricted to tropical forest areas, including ...

Dr. Richard Cifelli, who was one of the leaders in the discovery, is the curator of ... of the Sauropod family ate conifers, which was the most widely eaten plant during that time. They also ate other plants such as ferns, club mosses, horsetails, and cycads. Although dinosaurs of this family had different diets, they ultimately consist of the same types of vegetation (Zoom Dinosaur). Sauropods we...
