Preliminary Screening of Bioactive Natural Products

The plants which are used to cure diseases are called medicinal plants. This property of plants is due to the presence of certain chemicals namely Phytochemicals which include alkaloids, Glycosides, flavanoids, volatile oils, vitamins, resins, gums etc. These chemicals terminate the growth of micro organisms by obstructing one or many metabolic activities of microbes. World Health Organisation has estimated that perhaps 80 % of the Earth’s inhabitants rely upon traditional medicine for their primary health care needs and a major…

Reaction Paper_ Film About Life the Forest Has

The film that we watched showed what kind of life the forest has and how large diversity of life inhabits in it. The trees are not only the living things that exist in it but many kinds of animals and insects as well.

Pandan as Cockroach Repellent

Any home can have cockroaches. They are scavengers and a health hazard. While walking on spoiled food in garbage containers, they pick up various bacterial organisms on their legs that they can later deposit on uncovered food. Cockroaches themselves are not implicated in the transmission of any diseases. However, many disease-causing organisms can grow and multiply in their guts and can then be deposited on silverware, plates etc. during defecation. For example, cockroaches can pick up disease-causing bacteria like Salmonella…

Biology Botany Study Guide

9.1.3 Distribution of tissues in leaves and functions In the leaf you have xylem and phloem tissues. Xylem tissues act like transport tubes, transporting water and minerals. Phloem tissues are used to transport sugars and water (sap). When each of these tissues are connected with each other throughout the plant, they form a circulatory system. 9.1.4 modification of roots * Roots become swollen with food (starch, oils, etc) for storage in cortex cells * All have a “uniform” shape and…

The Effect of Different Levels of Radiation in Growth of Plants

ABSTRACT The effect of different levels of radiation was determined using four set-ups-10kR, 30kR, 50 kR, and the control (no radiation). The four set-ups were observed for nine weeks and growth (in cm), germination, and survival rate was measured. Results showed that at the right level of radiation level (10 kR), radiation have a positive effect on the plant growth and has the same germination and survival rate from the control set up. The 30 kR set up and 50…

Relationships Between Humans & Plants& Animals

Humans, animals and plants have a great relationship with each other, they need each other, and they make each other’s lives better. Without plants and animals, human won’t be able to survive or can not live till now because humans need plants and animals to feed themselves. On the other hand, plants aren’t able to grow, too because they need to be taken care by humans. Therefore, human should protect both animals and plants. But human couldn’t take good care…

Soil Formation

Soil formation, or pedogenesis, is the combined effect of physical, chemical, biological and anthropogenic processes on soil parent material. Soil is said to be formed when organic matter has accumulated and colloids washed downward, leaving deposits of clay, humus, iron oxide, carbonate, and gypsum. As a result, horizons form in the soil profile. These constituents are moved (translocated) from one level to another by water and animal activity. The alteration and movement of materials within a soil causes the formation…

Plant Cloning

The normal sexual reproduction of organisms, including plants, involves the passing on of half the number of chromosomes of one parent and the corresponding half by the other parent so that the offspring still ends up with the same number of chromosomes as with its parents. However, during the process of meiosis, i.e. cell division which occurs in preparation for reproduction, segments from one chromosome cross over to their corresponding segment in the homologous chromosome. In addition, chromosomes from each…

Direct Seeding Literature Review

Introduction: The world’s total forest area is just over 4 billion hectares, which corresponds to an average of 0.6 ha per capita (Figure 1). The five most forest-rich countries (the Russian Federation, Brazil, Canada, the United States of America and China) account for more than half of the total forest area. Deforestation – mainly the conversion of tropical forest to agricultural land – shows signs of decreasing in several countries. Around 13 million hectares of forest were converted to other…

Fast Plants Materials and Methods

When first preparing our fast plants we had to set up four different systems that would dictate our variable of fluorescent light. Each system would provide light to our fast plants for different amounts of time per day. Our systems were set up for 0 hours of light, 6 hours of light, 12 hours of light, and 24 hours of light. To setup the lab we began to setup our lighting system with fluorescent a timer for each set of…
