Photosynthesis is process by which green plants and certain other organisms use the energy of light to convert carbon dioxide and water into the simple sugar glucose. In so doing‚ photosynthesis provides the basic energy source for virtually all organisms. An extremely important byproduct of photosynthesis is oxygen‚ on which most organisms depend. Photosynthesis occurs in green plants‚ seaweeds‚ algae‚ and certain bacteria. These organisms are veritable sugar factories‚ producing millions of

Background Theory Photosynthesis: Plants require water from the soil‚ sunlight and carbon dioxide found in the atmosphere for growth and development. In the process of photosynthesis‚ carbon dioxide and water – in the presence of chlorophyll and light energy – are converted into sugar and oxygen‚ which is given off as a by-product. Generally‚ as sunlight increases in intensity‚ the rate of photosynthesis also increases [1]. This means greater food production within the plant. Many garden vegetables

the relationship of different wavelengths of light and the rate of photosynthesis in spinach leafs. The rate of photosynthesis was measured every five min under light colors of white‚ green‚ red‚ blue and yellow under a light intensity of 2000 lux. The rate of photosynthesis was measured by the spinach disk method in which we replaced the air from the disks with sodium bicarbonate using a vacuum. Under photosynthesis‚ oxygen‚ a product of photosynthesis‚ replaced the bicarbonate solution‚ made the

BEAN LAB My hypothesis was the white beans would stand out but the black and green beans would be camouflage. For my prediction I said that if the predator consumes more white beans than black. Therefor‚ the white bean population will decrease. In the “beetles” environment the predominant colors are brown‚ green‚ black and tan; and the predominant colors for beans being brown‚ black‚ green and white. Knowing the predominant colors of the environment and of the “beetles” would show that the white

In photosynthesis‚ light energy is transformed into chemical energy‚ thus chemical energy is the product. This is different from respiration because respiration transforms chemical energy into energy usable by cells; in this case chemical energy is the source. Photosynthesis occurs in the chloroplasts‚ using the chlorophyll inside of the chloroplasts‚ while respiration occurs in the mitochondria. Photosynthesis produces oxygen as a by-product‚ while aerobic respiration requires oxygen to even work

I can model Photosynthesis with The Law of Conservation Of matter and The Law of Conservation of energy. I know this because of the articles i’ve read the articles are Discovering the secrets of Photosynthesis‚ Joseph Priestley‚ Discoverer of Oxygen and Photosynthesis: Yucky chemistry Details. Photosynthesis is a good example of the Law of conservation of Energy because in the process of Photosynthesis the radiant energy is absorbed by the plant. The radiant energy is then turned into chemical

Photosynthesis Lab Report Purpose: To research the effect of different wavelengths (colors) of light on plant growth during photosynthesis. Background Information: Photosynthesis is the process by which sunlight is captured by chloroplasts within plant cells and turned into energy. This energy is used to help the plant grow roots‚ leaves‚ flowers and fruit. Energy is required by living things

6CO 2 + 12H 2 O + light → C 6 H 12 O 6 + 6O 2 + 6H 2 O Introduction: In this simulation‚ you will be looking at the production of carbon dioxide as a plant photosynthesizes. Oxygen is measured in the number of bubbles produced by the plant. Three factors that influence the rate of photosynthesis can be adjusted in the simulator to determine how each of the factors affects the rate of photosynthesis.

Notes about bean germination: * The time to germination will decrease if you soak the beans overnight * It may take 7-10 days for the beans to ‘sprout’ * Make sure the paper towels remain moist for the duration of your experiment | | | | | | | | | | Procedure 1. Think of 10-20 variables that may affect seed germination‚ recording them in Table 3. 2. From your list of variables in Table 3‚ select three to test. Form a hypothesis for why each affects seed germination
