Introduction : 

Introduction Plants and plant communities (places where a variety of plants live together) are very important to humans and their environment. Here are some of the important things plants provide. Plants have great "aesthetic" value which means they add to the beauty of the places that we live. How many of us would be want to live without the plants around us, including the forests, woodlands, and grasslands surrounding our towns and cities? Native grasses and wildflowers provide use with a link to our history. Throughout history plants have been of great importance to medicine. Eighty percent of all medicinal drugs originate in wild plants. In fact, 25 percent of all prescriptions written annually in the United States contain chemicals from plants. The oxygen in the air we breathe comes from the photosynthesis of plants. The quality of the air can be greatly influenced by plants. Plants can stop the movement of dust and pollutants. Through the intake of carbon dioxide, plants can also lessen the greenhouse effect caused from the burning of fossil fuels like coal. Plants are also very important for the goods they provide. Fibers from plants provide clothing. Wood used to build our homes depends on plants. Some fuel products are made from plants, like ethanol made from corn and soy diesel made from soybeans. We will study this for us to appreciate the importance of plants to ous society.

CHAPTER I The Problem and Its Background

Slide 5: 

I. Background of the Study When dextrose comes to our mind, we think that this is one of the agents to heal the ailments of the patients. First and foremost, what is the relationship of dextrose on plants? Plants require three essentials, light, water and nutrients to thrive and produce optimum yield. Plants naturally produce sugars, such as glucose and sucrose. These sugars are needed to produce energy, promote growth and aide in the processes of respiration and transpiration. Sugar can also be introduced to a plant through watering to enhance growth and production.

Slide 6: 

Plants naturally produce the sugars such as glucose during photosynthesis. The sugar is produced to be stored for later conversion to energy for the organism. This production of sugars also aids in the absorption of nutrients and minerals. Sugar helps a plant to grow and helps to regulate gene expression by causing less water to be moved to the plant's roots. Plant sugars are converted to energy. This energy is then used to build new cell tissue. The energy produced by glucose also induces the process of cellular respiration.

Slide 7: 

Dextrose is simply a form of glucose. Some food packagers like to use "dextrose" on their packaging instead of "glucose" because they believe that people have negative associations with glucose. This sugar is extremely abundant in nature, and it can be found in numerous plant and animal tissues, often along with other sugars such as fructose. The body relies on glucose for energy, using this sugar to power cells. When people measure their blood sugar, they are actually measuring the amount of dissolved glucose in the blood.

Slide 8: 

Sugar helps a plant to grow and helps to regulate gene expression by causing less water to be moved to the plant's roots. Glucose is converted to energy. This energy is then used to build new cell tissue. The energy produced by glucose also induces the process of cellular respiration.  Sugars help the soil to retain more moisture. Sugar doesn't draw water away from the plant as salt does, therefore, it keeps the plant from getting dehydrated as well. Glucose production increases the overall strength and health of the plant.

Slide 9: 

Dextrose, in moderation, is not harmful to plants. If the amount of dextrose in the soil becomes too high, this promotes a higher incidence of fungi and bacteria. A typical fungus that thrives on sugar is yeast. Excess amounts of yeast causes an increase in the risk of an infection to plants and humans.

Slide 10: 

II. Significance of the Study Sometimes a pinch of sugar is added to water and fed to a plant that has wilted and hasn't been watered for a while. The sugar can help the plant quickly get back to normal. However, this doesn't always work and sometimes the plant might be too far gone to save. Also, sometimes a pinch of sugar is added to the water that cut flowers are sitting in order to preserve them for a bit longer. However, sugar is not usually added to the water that is fed to normal, healthy plants. This is needed for those who need a short period of time to produce plants and flowers.

Slide 11: 

III. Statement of the Problem While were studying this, there are some questions that can answer the problem of some farmers and planters. Here are some questions: How does dextrose affects the plants? How can it help the farmers in planting? In what other ways can dextrose help?

Slide 12: 

IV. Scope and Delimitations We will study this just to prove that dextrose affects the growth of plants. We will also study this to help farmers what agent to be used in farming. We’ll not study what is the effect of dextrose on other living organisms and its effect on our society.
