to occur‚ photosynthesis must be greater than respiration. High temperatures (35°C) cause increased respiration‚ sometimes above the rate of photosynthesis. This means that the products of photosynthesis are being used more rapidly than they are being produced as a result the growth will not be sufficient and the lettuce plant might even die. On the contrary low temperatures ( 0°C ‚ -10°C ) can result in poor growth. Photosynthesis is slowed down at low temperatures. Since photosynthesis is slowed

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

atmosphere had a very different chemical make-up‚ high in carbon molecules; unsustainable for life as known today. These prokaryotes were the first photosynthetic organisms to release oxygen into the atmosphere (Campbell‚ Reece‚ & Simon‚ 2007). Photosynthesis is using light energy to produce sugars and other types of organic food molecules from water and carbon dioxide. This process is used by plants‚ autotrophic protists and some bacteria. The end result of which releases unadulterated pure oxygen

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

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
