Section November 7‚ 2012 Abstract The effect of water and fertilizer on corn seedlings was examined. It was hypothesized before the experiment that enough water with sunlight and air should make the plants grow healthy. It has to do with photosynthesis. Fertilizer is also going to make the plants grow much faster; this is because of the nutrients in it. The experiment took about four to six weeks to complete; it took some days for the seed to germinate before planting. The corn was growing there

called Photosynthesis. The food that they produce is the sugar glucose. Animals and other organisms are heterotrophs (other- feeders). They must consume other organisms (plants) in order to eventually get their glucose. Both plants and animals use glucose as an input to the process of Cellular Respiration (another subject) to produce ATP molecules. ATP molecules are the energy source for all metabolic processes. Log on to the following web site for a good explanation of photosynthesis. Pay attention

When comparing and contrasting the mitochondria and chloroplast‚ a person learns all of the similarities and differences between the two. In this essay‚ you will read about the mitochondria‚ the chloroplast‚ and their biochemical reactions. The mitochondria often referred to as the powerhouse cell is found in the eukaruotic cells. There‚ those cells are often found in groups of hundreds. Mitochondria cells can be anywhere from 1 to 10 um long in length‚ but are able to change shapes‚ move‚ and divide

Growth Introduction Photosynthesis is the process of converting light energy to chemical energy and storing it in the bonds of sugar. Plants need water‚ Co2 and light energy to create sugar. Photosynthesis occurs mainly in leaves and in 2 phases: light reaction and dark reaction. The light reactions converts light energy to chemical (Biology.clc.uc.edu‚ 2014). This chemical reaction must take place in the thylakoid membrane. Chlorophyll (the green pigment involved in photosynthesis) and several other

of CO2. These values of the photosynthesis (plus respiration) rates in red light were 0.443‚ -0.141‚ and -1.1 ppm/g/min with a mean value of -0.27 ppm/g/min. The values of photosynthesis (plus respiration) rates in blue light were 2.449‚ 1.667‚ and 2.997 ppm/g/min with a mean value of 2.36 ppm/g/min. A t-test comparing the mean photosynthetic rates under red and blue light indicated no significant difference

Plant Transport Plants are mostly made up of water. Lettuce is about 94% water and a potato is about 77% water. Plants need water for three main purposes: ------photosynthesis‚ -support -transport of chemicals Water is a raw material for photosynthesis. If water is in short supply‚ the rate of photosynthesis will be limited. Plants need water for support‚ otherwise they wilt. Water is needed to transport many chemicals within plants. Chemicals‚ such as mineral salts‚ dissolve in water and

they can source water whereas fungi can live almost anywhere so long as it has other small organisms nearby. Plants make their own food‚ using water and carbon dioxide to make glucose (energy) and oxygen (a waste product) in a process called photosynthesis. Though very little of it‚ it also lets out some carbon dioxide. This is the reason that it has adapted to live in places with lots of sunlight- so it can absorbed enough of it to make energy. It also grows in ground that has a water source. Different

molecules) to fit inside them. The place where these substrate molecules fit into is called the active site. The enzymes are denatured if the shape of the enzyme changes and the active site will no longer work. The enzymes involved in respiration‚ photosynthesis and protein synthesis work inside cells. Other enzymes are produced by specialised cells and released from them. The digestive enzymes are like this. They pass out into the gut‚ where they catalyse the breakdown of food molecules. Different
