to show the effects that different colors of light have on plant growth. We separated our plants into different boxes and then covered the openings with colored cellophane. We conducted this experiment for approximately two weeks. Out of the colors blue‚ green‚ red‚ and yellow‚ the plant behind the blue cellophane grew the most. Research Problem What effects does different color light have on plant growth? Hypothesis The plants will grow taller under the red and blue light opposed to the

Economic Issues Economic Growth Economic Growth involves an increase in the volume of goods and services that an economy produces over a period of time. It is measured by the annual rate of change in real Gross Domestic Product (GDP)‚ i.e. the percentage increase in the value of goods and services produced in an economy over a period of time‚ usually one year‚ adjusted for inflation Aggregate Demand Aggregate Demand (AD) is the total level of expenditure in the economy over a given period

after a week of measuring the biggest plant per bag. Each day the biggest radish plant in site A was measured and by day five the largest plant was 5 centimeters long‚ and had developed small green leaves. By the 5th day site B and D’s seeds showed no signs of growing and length remained at 0 centimeters. Site C and D’s superior seed both grew a total of 3 centimeters according to the 5th day measurements. Both the graph and table display the same results. The plants were measured with a ruler and then

pollution emitted by human activities‚ such as factories‚ electrical power plants and automobiles. Two main pollutants are sulfur dioxide (SO2) and nitrogen dioxide (NO2)‚ which reacts with substances in the atmosphere‚ such as water and oxygen‚ to form acid rain. While rain water has a pH of 5.6‚ acid rain has a pH of 5 or less‚ which is acidic enough to harm plant life. Due to the reactivity of acid rain‚ the cell processes of plants are disrupted‚ and the cells die or become unable to function properly

Plant Structure and Function Plant Body The unique organization of tissues in flowering plants is part of the reason why they are the dominant group of the plant kingdom. Monocots and Dicots Meristems Meristems – region of undifferentiated cells that can divide rapidly. Apical meristems – shoots and tip of roots (primary growth) Lateral meristems – thickening of the cambium (secondary growth) Plant Tissues Plant Tissues Xylem – conducts water and mineral ions; fluids can

Antimicrobial Properties of Plants A plant with antimicrobial properties means that it destroys or inhibits the growth of bacteria and fungi. Aim: our aim was to see weather or not garlic‚ mint and grass contained antimicrobial properties and if they did how effective they were we were trying to see weather the bacteria will grow around the different plants. Control Test: As a control test what we did was‚ we dipped a paper disc into the alcohol solution we used to dissolve the plants; the reason we

Coffee Beans - Robusta vs Arabica Taste Arabica beans have a milder‚ more aromatic taste while Robusta beans hold a stronger‚ more acquired flavour‚ with a grain-like overtone and peanutty aftertaste. Arabica beans tend to have a sweeter‚ softer taste‚ with tones of sugar‚ fruit‚ and berries. Their acidity is higher‚ with that winey taste that characterizes coffee with excellent acidity. Robusta beans contain twice as much caffeine as Arabica beans. Shape Arabica beans are flat and

This lab was testing different methods to prevent bean beetles form infesting a chickpea harvest. They wanted to find something that would protect the crop from this invasive creature. To do this they created 3 replicate experiments which contained 25g of seeds each group with a different genotype‚ and 5 newly hatched adult C. maculatus were added to the jar. They continued to check this on a weekly basis‚ at the end of the experiment they found that the results where quite different for each jar
