Germination is the process of the plant embryo sprouting a seedling after a period of dormancy in a seed. (The Columbia Encyclopedia, 6th ed., 2008) Dormancy comes from the Latin word meaning “to sleep.” This period of inaction in the seed is an adaptation to support the seed so it can survive though the harsh growing conditions. (Campbell, Reece, Urry, Cain, Qasserman, Minorsky & Jackson, 2008) Once these poor conditions are absent, the seed can then germinate. The seed will absorb the water
in between plant species are of great importance and often result in fierce competition within the community. Over the past decades, increasing in human activity and movement allowed certain species to migrate beyond their origins and vastly expand in population, plants being one of the most complicated organisms on earth were highly involved in such activity. This enabled invasions by alien plants which poses serious threats and may inflict negative impacts to native species of plants in an certain
Adaptation of Land Plants The plants that we know today as terrestrial organisms were not always on land. The land plants of today can be linked back to aquatic organisms that existed millions of years ago. In fact, early fossil evidence shows that the earliest land plants could have arisen some 450 million years ago (Weng & Chappie 2010). Plants that used to reside strictly in water were able to adapt in ways that allowed them to move onto land. It is speculated the need for plants to move onto land
species of plants and animals, with more than 2,100 being native (IConserve, 2007). It is critical to appreciate the sustainable use of these natural resources that influence our beautiful state’s economic health and quality of life of all Pennsylvanians. Yet many threats to our home’s biodiversity are present. One significant threat is invasive plant species that are eliminating native plant species. Invasive plants are plants which grow aggressively, spreading and displacing other plants (Ball
reproduction. Cuttings are taken from a mother plant in vegatative growth, and rooted in hydroponic medium to be grown as a separate plant. The offspring will be plants that are identical to the parent plant. Cloning preserves the character of your favorite plant. Cloning can make an ocean of green out of a single plant, so it is a powerful tool for growing large crops, and will fill a closet quickly with your favorite genetics. When you find the plant you want to be your "buddy" for the rest of your
The Tea Plant The tea plant (Camellia sinensis) is one of about 80 species of East Asian evergreen shrubs and trees that belong to the tea family, or Theaceae. Tea reaches a height of 9 meters but is kept pruned to a low, mounded shrub in cultivation. The foliage is emerald green, while the flowers are fragrant, yellow-centered, white and about 4 centimeters wide. History Tea plant cultivation began about 4,000 years ago in its native country, China. The Japanese did not discover the plant
Plants and Superstitions For many years plants have played a large part in superstitions. Although, they are not so much believed now, as they used to be. They were used to help one's fortune, wealth and fertility. It is amazing that bread was ever eaten; there were so many superstitions about it. It was used to aid in all of these things and many more, It is ironic, however, that the one thing they worshipped and used to keep harm and disease away made them ill and killed some of them. When all
Introduction Plants exhibit exceptionally intelligent behaviour when it comes to interactions with their environment. They can detect perceived threats, then convey warning signals to other plants via chemical signaling. Forewarned plants will then assemble their defenses against these potential threats, thus, increasing their chance of survival and reproduction. Communication and competition are common occurrences among the plant world. Another brilliantly, almost inconceivable capability plants possess
Humans depend on plants in numerous ways. One reason we depend on plants is for consumption. Plants have the unique ability of producing their own food through a process called photosynthesis. In this process, plants are able to produce macromolecules such as carbohydrates that cannot be produced in animals or humans. In humans, the only to gain these macromolecules is to consume plant matter, or consume plant-eating animals (herbivores). When humans consume plants, the carbohydrates, lipids, and
Carnivorous Plants In a world where plants are at the bottom of the food-chain, some individual plant species have evolved ways to reverse the order we expect to find in nature. These insectivorous plants, as they are sometimes called, are the predators , rather than the passive prey. Adaptions such as odiferous lures and trapping mechanisms have made it possible for these photosynthesizers to capture, chemically break-down and digest insect prey (and in some cases even small animals.) There is
Plant defences are those mechanisms employed by plants in response to herbivory and parasitism. According to Hanley et al. (2007), “the tissues of virtually all terrestrial, freshwater, and marine plants have qualities that to some degree reduce herbivory, including low nitrogen concentration, low moisture content, toxins or digestibility-reducing compounds”. The type of chemical defence may be species specific (Scott 2008). The defences that plants possess may be in the form of chemical production
Plants are the primary producers in Earth’s ecosystem. Plants are autotropic, meaning they can produce their own food by the process of photosynthesis and as a result ultimately produce food for the ecosystem’s consumers. Understanding plant function is the key to enhancing crop production, medicine production, preservation of plant bio diversity etc. The plant kingdom is a treasure house of potential drugs and in the recent years there has been an increasing awareness about the importance of medicinal
As plants evolved, moving from the sea to land, there were many adaptations that needed to occur to sustain the new mode of life. Adaptations addressed the major problems of how to prevent water loss, how to transport water, and how to reproduce in a newly dry environment (Lecture 4). Different organisms addressed these issues in a variety of ways, giving rise to anatomical differences in tissues and biochemical changes, which contributed to the rise in genetic variation of plant species. First
oilseed plant that bears the same name. The sesame plant is also thought to be one of the oldest cultivated plants in the world (Hansen, 2011). This plant is chronicled to have existed about 3000 years ago in Babylon and in Egypt, and is said to have originated in sub- Saharan Africa (Hansen, 2011). Although the sesame plant originated in Africa, through commerce and trade it has reached the entire globe. The sesame plant is now grown throughout the world. CULTIVATION The sesame seed plant is a short
Photosynthesis is a vital process used by plants, some protists, and cyanobacteria in which the light energy coming from the sun is transformed into chemical energy. Chemical energy, then, can be used for cellular processes and stored in the form of glucose, which is essential for life on earth since it fuels the metabolic process of cells (Morris & Moat, 2016, p.227). The purpose of this experiment is to separate and analyze photosynthetic pigments and determine the absorption spectrum of spinach
When moving a plant from one place to another, suggest why it is important to leave some original soil from the roots. It is important to leave some original soil from the roots when moving a plant in order to avoid damaging the roots and also to initially keep the roots with some nutrients from the previous location. The plant will need to get accustomed to the new soil with original soil it will create an easier transition. 2. What is the usual cause of a plant wilting? A plant wilts due to not
There are numerous adaptations that plants make to suit its environment. The cotton plants are ones that have adapted its structural features, internal functions and behaviour responses to cope with its new environment and condition. Cotton grows from cotton plants and they can be used to make food or products. It is a soft, white substance used to make fabrics, thread, and garments. Cotton is among the most common and comfortable fabric used to produce clothing. Oil can be obtained from cotton
A plant food is any material /substance of natural or artificial origin that's applied to soils or to plant to produce one or a lot of plant nutrient essential to the expansion of and development of plants. plant food is any substance accustomed add nutrients to the soil to market soil fertility and increase plant growth. Fertilisers helps to reinforce the plant growth. merely plant food area unit nothing however the plant nutrients. Fertilisers is classified into 2 categories: organic or inorganic
his semester intrigued my curiosity about plants , and how are they seen in this modern society. Nowadays plants are not seeing as a priority like back in the days. Before the industrialization the agricultures was one of the primary money maker. Nowadays what has being making money and being important to society has being the different innovations in technology. Plants have being gradually forgotten in the past couple of centuries (industrialization 1800s) . As a biology major, this semester I
research is mainly focused on indigenous knowledge systems and plants. The purpose of this investigation is to research the main uses of indigenous plants and how they are used. This includes their medicinal uses to cure ailments. I have chosen to base my research project on the following medicinal plants: Cancer Bush, Cape Aloe, Lemon, Garlic, Hoodia and the Devil’s Claw. I will also investigate the uses of these traditional medicinal plants methods. This will include how they are widely approved and
