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

Experiment 1 Cyanobacteria Oxygen Production Through Photosynthesis Date Performed: September 2‚ 2014 I. Introduction a. Background Cyanobacteria or blue green algae are renowned for their tolerability and susceptibility even in wide range of environmental conditions‚ a characteristic of many primitive organisms. CNB are believed to be the agents of autotrophic origin of life thus they probably represent the survivors of the earliest photosynthetic plants‚ along with photosynthetic and chemosynthetic

consumers are very small‚ and they are easily contained in a liter of water. If you put these organisms in a bottle and turn on the lights‚ you get photosynthesis. If you turn off the lights‚ you turn off the primary production. Darkness has no effect on respiration. This is because cellular respiration is actually the reverse process of photosynthesis. Oxygen is a necessity of life requirements for basically all living organisms.* In this lab we are testing how different levels of salinity in the

Problem: Why do leaves change color in the fall? Background: Leaves contain many pigments such as chlorophyll b‚ xanthophyll‚ and beta carotene besides chlorophyll a. They are part of the photosystem in the thylakoids. Pigment molecules can be separated by a procedure called chromatography. The procedure uses a special paper and solvent. The chlorophyll molecules adhere to the paper. The solvent molecules move up the paper by capillary action. Each chlorophyll molecule will travel up the paper at

this process‚ also known as photosynthesis to happen it involves three different pigments that give the leaves their color. Trees are autotrophs; this means that they make their own food. The leaves obtain water through their roots‚ but also they need sunlight‚ carbon dioxide‚ and chlorophyll. Chlorophyll is the pigment that gives leaves their green color and makes photosynthesis happen. Without photosynthesis or chlorophyll the leaves would stay the same‚ Photosynthesis (which means putting together

using the sun’s energy to transform carbon dioxide and water into glucose. In this process of photosynthesis‚ plants convert the sun’s energy into chemical energy that is stored in the bonds of the glucose molecule. Glucose is a simple carbohydrate that provides immediate fuel to cells but it is also a building block for more complex carbohydrates stored by living organisms for future use. For photosynthesis to transform light energy from the sun into chemical energy (bond energy) in plants‚ the pigment

organisms need to survive. Carbon is the basic building block of all living things. It moves through an ecosystem in a cycle called the carbon cycle. In this cycle carbon in the atmosphere is known as carbon dioxide. Plants use it to perform photosynthesis and make food. Animals then eat the plants that contained the carbon. Carnivores then eat the other animals thus releasing carbon in animals. Both plants and animals respire. Carbon dioxide is returned to the atmosphere through respiration and

the structures are called stomata.[1] Leaf transpiration occurs through stomata‚ and can be as a necessary "cost" associated with many processes such as the opening of the pistil and allowing the diffusion of carbon dioxide gas from the air for photosynthesis. Transpiration also cools plants and enables mass flow of mineral nutrients and water from roots to shoots. Water is absorbed at the roots by osmosis‚ and any dissolved mineral nutrients travel with it through the xylem. The rate of transpiration
