Aquaponics system is a food production system that combines conventional aquaculture‚ raising aquatic animals such as snails‚ fish‚ crayfish or prawns in tanks‚ with hydroponics cultivating plants in water in a symbiotic environment. In normal aquaculture‚ excretions from the animals being raised can accumulate in the water‚ increasing toxicity. In an aquaponic system‚ water from an aquaculture system is fed to a hydroponic system where the by-products are broken down by nitrogen-fixing bacteria

Introduction and Background: Photosynthesis is the process in which light energy is converted to chemical energy‚ and allows plants to grow‚ flower and produce seed. The process of photosynthesis requires an organelle called chloroplast and a pigment called chlorophyll The energy of the light is absorbed by chlorophyll and in turn supplies the plant with energy to transform carbon dioxide and water into oxygen and carbohydrates. (lab handout). The process of photosynthesis requires an organelle called

Research Question: How does varying distance of light away from papaya leaf discs at 10cm‚ 15cm‚ 20cm‚ and 25cm affect time taken in seconds for all five discs to rise and float on the surface of the water? Hypothesis: “As the distance of light away from papaya leaf discs increases‚ the average time taken for the discs to resurface and float o the surface of the water increases.” Data Collection & Processing Raw Data Table: Time taken (minutes)

Research Question: How do differing leaf heights affect the number/density of stomata of a leaf? Hypothesis Stomata are pores‚ typically found under the leaf (lower epidermis)‚ that control the gas exchange of transpiration‚ where water vapor leaves the plants‚ and carbon dioxide enters. I predict that the stomatal density on high leafs is higher than on low leafs. During photosynthesis the chloroplasts in the leaf cells synthesize ATP from ADP as a result of exposure to light‚ while oxygen

(cm)) (±0.05) on the photosynthetic rate by counting the number of oxygen bubbles rising up the test tube per minute (bubbles min^(-1)). The hypothesis was supported because as the light intensity increased‚ the rate at which oxygen bubbles rising to the top of the test tube also increased – for example‚ at the closest distance of 5 cm‚ the rate of photosynthesis was at its highest‚ with the optimum amount of oxygen bubbles being produced. At a distance of 5cm‚ the average number of bubbles counted

Dennis Carrasco 11-20-12 Introduction For this project we had to experiment to see the effects of blue light on a plants growth. We had to research on light and its effects on photosynthesis. This helped me with my experiment because I had knowledge for what was going on with the plants and light. For this project I and one of my classmates had to conduct a experiment to see the effects of blue light versus white light. For this project we had to grow lentil beans under white and blue light and
