Put simply‚ photosynthesis is the process of converting light energy into chemical energy and storing it in the bonds of sugar. Photosynthesis comes from the Greek language and literally means “Light Composition” or “Putting Together Light.” Photosynthesis generally takes place in plants‚ however it also takes place in algae and many species of bacteria. In photosynthesis‚ light energy is converted to chemical energy and the chemical energy is then stored in the form of glucose‚ or sugar. Carbon

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

Photosynthesis is a process that allows organisms to trap sunlight energy and convert it directly into potential chemical energy. Enzymes are required in order for the biochemical reactions to occur because they act as a catalyst to convert energy from sunlight into chemical potential energy. Two consecutive steps allow the photosynthesis process to take place. These steps are light-independent reactions‚ and light dependent reactions. The occurrences of Light-independent reactions happen in the

germination of a seed affected by sunlight?” Experimental Hypothesis: We believe these results will occur. 1. The seeds that are water deprived (1 mL of H2O a day) will not grow very well due to a lack of water which is important in photosynthesis and also lacks nutrients. The seeds may also die off due to a lack of water. 2. The seeds that are have a proper amount of water (10 mL of H2O a day) will grow the best and achieve the greatest height‚ and overall best appearance.

Autumn Leaves Trees have green leaves due to the abundance of chlorophyll and chloroplasts in leaves. These organelles absorb‚ store and convert light energy from the sun and is necessary photosynthesis to occur. These organelles reflect green light which attributes to the green color of leaves. The leaves change color in the fall and winter do to the shortened times of daylight and lower temperatures. Trees also divert nutrients from leaves to store in twigs and branches for preparation of winter

spinach beet to various light conditions. Introduction Chlorophyll‚ an important pigment in chloroplasts‚ is an essential component in photosynthesis; converting electromagnetic radiation from the sun into potential chemical energy. Photons excite electrons in chlorophyll which move through the electron transport chain‚ resulting in energy being stored in the bonds of ATP and NADPH. The flow of electron through the electron transport chain can be measured using DCPIP‚ a blue chemical which turns colourless

Solar Vehicle EGR 100 12/3/2013 Introduction Living on Michigan State’s campus‚ one is constantly reminded to “Be Spartan Green”‚ whether it is turning off the lights or taking a shorter shower‚ Spartans are always striving to be the most ecofriendly students that any university could have. The problem at hand is to create a vehicle using only green technology‚ such as solar panels‚ and have this car race up a ramp as fast as possible‚ with a shorter time being ideal. There are many requirements for this project

McDonald’s using Blue Ocean Strategy McDonald’s is using Blue Ocean Strategy (BOS). Blue Ocean Strategy states that an organization can produce higher growth and profits by creating new demand in an uncontested market space than by competing head-to-head with other suppliers for known customers in an existing industry. First‚ McDonald’s is using the value innovation concept of BOS. By this‚ McDonald’s believe that product/service differentiation and lower cost are achievable simultaneously. The
