Global Warming and the Effect on Plant Diversity - 2318.
Our dependencies on tropical plants are vast ranging from the daily essentials of food and shelter, to cures for cancer and possibly AIDS. As destruction of the rainforest continues, the effects on plants are immense through the loss of genetic diversity and the disappearance of species. Plant species extinction is reaching critical levels.Essay on the Introduction to Flowering Plants: The flowering plants or angiosperms (Angiospermae or Magnoliophyta) are the most diverse group of land plants. The flowering plants and the gymnosperms are the only extant groups of seed plants.Diversity characterizes most living organisms, the our earth supports something like 5 to 10 million species of plants and animals (IUCN, 1980) which have been the result of 3 billion years of evolution involving mutation, recombination and natural selection.
DIVERSITY OF PLANTS Plants evolved more than 430 million years ago from multicellular green algae. By 300 million years ago, trees had evolved and formed forests, within which the diversification of vertebrates, insects, and fungi occurred. Roughly 266,000 species of plants are now living.Plant Diversity Paper Plants are extremely diverse multicellular photosynthetic organisms whose evolution can be traced back to one common ancestor. This common ancestor would most likely be some variation of the common day green algae.
Plant Diversity Essay. 3431 Words 14 Pages. Diversity in the Plant Kingdom I. Introduction All modern terrestrial plants are the descendants of algae that adapted to a terrestrial habitat roughly 500 million years ago. Compared to water, land is an erratic habitat where temperature and moisture availability may change abruptly and dramatically.
