1.The root grows thicker with age and helps support the tree.
2.In trees as large as the coast redwood of California, the water may travel 400 feet from the lowest roots to the highest leaves.
3.This seems against the laws of nature as the most efficient suction pump can raise water to only 33 feet.
4.Bryophytes are very small, even the "giants" of this group rarely grow taller than 15 centimetres.
5.The ferns are better adapted to land than bryophytes.
6.We probably depend much more on the flowering plants than on any other type of plants.
7.In vascular plants the sporophyte is more conspicuous than in bryophytes.
8.A genus is a larger group than a species.
9.Species of one genus are closer related to each other than to other kinds of plants.
10.All plants in the world may be divided into phyla, which are farther divided into smaller groups called classes.
