Everyone always loves the different color of leaves during the fall season‚ but nobody ever thinks of the scientific reasoning of why this happens. To find this answer‚ the search begins at the basic functions of life‚ cells. Within the plant cell‚ the dying off of chlorophyll causes the different color changes. Plants are autotrophs. Autotrophs are living things that make their own food. Plants make their food within their cells by using sunlight‚ and chlorophyll. This process of plants making

There are many variables that could affect the rate of photosynthesis and the net consumption of carbon dioxide. In this experiment‚ the effects of how the intensity of light energy affected photosynthesis were observed. Two pieces of elodea was placed into separate beakers and one of the beakers was placed under a bulb of lower intensity and the other beaker being placed under a higher intensity bulb. The results showed that the beaker under the higher intensity light energy had a higher consumption

This lab was split up into two different experiments‚ using different variables in each. During the first section of the lab‚ we investigated the what the effect of light is on both photosynthesis and cellular respiration. Our hypothesis about this effect was that the cuvette representing ‘no light’‚ being covered in foil‚ would result in a yellow CO2 indicator fluid‚ meaning that there was a decrease in pH and a high level of CO2 was present. Additionally‚ we hypothesized that the cuvette that was

Photosynthesis and Cellular Respiration lab makeup Photosynthesis absorbs energy from the the sunlight ‚and water‚and carbon dioxide to to create energy sugar ‚and oxygen. Photosynthesis also absorbs molecules that are called pigments. The process of photosynthesis is used by plants to make food for themselves. By then doing this‚ it also benefits us humans and animals by releasing carbon dioxide. Oxygen to them is considered a waste product‚ but a necessity to us. The photosynthesis

Photosynthesis Investigation Research Question How does length of pondweed affect the amount of bubbles produced in 2 minutes by pondweed during the process of photosynthesis? Independent variable: Length of pondweed (8/10/12 cm). Dependent variables: amount of bubbles produced in 2 minutes. Control variables: Volume of water in the beaker (500ml)‚ The volume of water has to be the same every time‚ so when doing the experiment I need to make sure I always use these 500 ml that i have already

Biology Investigation Problem: How does light affect the rate of Photosynthesis? The Plan In my experiment I am going to see how light affects the rate of photosynthesis. To do this experiment I am going to set up the apparatus as shown in figure 1. The apparatus I am going to use are the following: - 1 Tripod 1 300ml Beaker 1 Boiling Tube 1 Clamp Stand 1Clamp 1 Boss 1 Ring Binder 1 Lamp 1 1 Metre Ruler 1 Thermometer 1 Stop Clock To do the experiment I will set up the apparatus first.

from the air surrounding a plant. Photosynthesis is a process used by plants and other organisms to convert light energy‚ normally from the Sun‚ into chemical energy that can be later released to fuel the organisms’ activities. When light hits an object‚ it is absorbed or reflected. When it is absorbed it disappears from our sight and when it is reflected‚ we

Photosynthesis: Plant cells vs. Solar Cells Chevon Allen 01/23/2010 SCI-115 Professor Garcia Photosynthesis and the semiconductor-based solar cell are very similar process with different ways of reaching the same goal. In photosynthesis‚ plant cells harness the solar energy of the sun with carbon dioxide to transform water molecules into hydrogen‚ oxygen‚ and electrons. Just like photosynthesis‚ Semi conductor based solar cells harness the solar energy of the sun for the same purposes

For a century family medical leave has been an issue in the United States of America (). Many are faced with conflicts between their work duties and family responsibilities in the current work society. It is difficult enough for employees to take time off when they themselves are ill‚ but employees are than burdened with the responsibility to find suitable arrangements for their children‚ elderly parents and other obligations. There has been a long history of unfair labor practices concerning family

As Autumn approaches maple leaves start to lose their green color and then turn red‚ yellow and brown. In observing my first set of maple leaves I noticed a high concentration of black spots in the yellow areas of the maple leaves. This observation brought mine to the question of‚ Do the dark brown spots appear mostly in the yellow area compared to the red areas on the leaves? The first set of Red Maple leaves I observed black spots that seemed to appear in higher amounts on the yellow areas rather
