Excellent; I couldn’ t have written a better paper myself. 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. The two major groups of plants are the bryophytes and the vascular plants; the latter group consists of nine divisions that have living members. Bryophytes

The three basic organs of a vascular plant are the stems‚ leaves‚ and roots. The stems consist of nodes‚ where leaves attach‚ and internodes between the nodes. The stem is responsible for elongation of the plant and acts as a central axis for other organs to attach to. The roots help to anchor the plant as well as absorb water and nutrients

“The Private Life of Plants: Traveling” was a useful documentary to help clarify my understanding on how plants manage to spread their seeds and germinate. I enjoyed watching the different time lapses for the species of plants and it helped me to see exactly what happens rather than reading it in a book or seeing a simple picture. I was amazed at all the different mechanisms plants used to travel around and not stick to just one area. I did not expect the pointy spines of plants to allow them to grip

ENG 112 Body Paragraph Chris McCandless‘s admirers are wrong to believe that he was a deeply honest person. At some moments in Into the Wild‚ he was not an honest person. According to Westerberg‚ a McCandless’s friend‚ said‚ “He never explained why he’d changed his name” (Krakauer 18). When McCandless decided to make a trip into the wild‚ he changed his name; he did not even bring any identification with him. During the trip‚ everybody knew about him under the name Alex. Westerberg was a friend

INTRODUCTION Those plants that have healing properties are termed as medicinal plants or herbs. The plant kingdom is divided into several groups‚ but the botanical classification is beyond the scope of this section. However‚ medicinal plants can be simply classified as trees‚ shrubs‚ woody perennials‚ annuals and biennials‚ and climbers. (http://eatt1.tripod.com/amp1.html) Medicinal plants consist of components of therapeutic values and have been used as remedies for human diseases

2011 Plants and Nitrogen Lab Report Introduction: Plants need ammonia‚ a combination of nitrogen and hydrogen‚ or nitrate‚ a form of inorganic nitrogen to grow. Most nitrogen is found in the atmosphere. However‚ plants and animals cannot directly absorb the nitrogen found in the atmosphere. Instead nitrogen gas is captured from the air by species of bacteria that lie in the water‚ soil‚ or grow on the roots of some plants. These bacteria convert the nitrogen into a form usable by plants. The

There is an overabundance of green plant life that strives on the heavy rains received each year. The forest floor is full of nutrients which the large tree strive on giving the canopy effects and which houses so much plant and animal life. 2.

surface of water and mud. Algae were evolving at the water’s edge‚ and one group – probably the charophytes – gave rise to plants. Cooksonia‚ a simple branching plant a few centimeters tall‚ evolved by 430 million years ago. It took another 160 million years for the taller Psilophyton to evolve. Then the evolutionary pace picked up. It took only 60 million years for plants radiate from the swampy lowlands to high mountains and nearly all places in between. They did so through modifications in

The flour produced from the cassava plant‚ which on account of its low content of noncarbohydrate constituents might well be called a starch‚ is known in world trade as tapioca flour. It is used directly‚ made into a group of baked or gelatinized products or manufactured into glucose‚ dextrins and other products. Starchy foods have always been one of the staples of the human diet. They are mostly consumed in starch-bearing plants or in foods to which commercial starch or its derivatives have been
