Photosynthesis The leaves are the part of a plant where most photosynthesis takes place. If you cut a leaf in half and look at the cut end‚ it would look like this: Key: 1. Waxy cuticle: this gives the leaf a waterproof layer‚ which lets in light. 2. Upper epidermis: provides an upper surface. 3. Palisade cells: contain chloroplasts. 4. Spongy mesophyll: collection of damp‚ loosely packed cells. 5. Lower epidermis: layer of cells on the lower surface. 6. Air

“Investigate the factors affecting the rate of yeast respiration” Lab Report Introduction The aim of this experiment was to investigate the effect of different amounts of a substrate on the respiration rate of yeast and to compare this to the effect of different amounts of glucose on the rate of yeast respiration. The substrate which I chose to further investigate was fructose. Fructose is a fruit sugar which is one of the three‚ along with glucose and galactose‚ dietary monosaccharides that

The term carbon footprint‚ therefore‚ is a shorthand to describe the best estimate that we can get of the full climate change impact of something. That something could be anything – an activity‚ an item‚ a lifestyle‚ a company‚ a country or even the whole world. CO2e? What’s that? Man-made climate change‚ or global warming‚ is caused by the release of certain types of gas into the atmosphere. The dominant man-made greenhouse gas is carbon dioxide (CO2)‚ which is emitted whenever we burn fossil

Carbon tax is an environmental tax levied on the carbon content of fuels. It is a form of carbon pricing. Carbon is present in every hydrocarbon fuel ‚ such as coal‚ petroleum‚ and natural gas. It is then released as carbon dioxide (CO2) when they are burnt. In contrast‚ non-combustion energy sources—wind‚sunlight‚ hydropower‚ and nuclear—do not convert hydrocarbons to CO2. CO2 is a heat-trapping "greenhouse" gas. Scientists have debated and discussed the potential effects on the climate system of

PHOTOSYNTHESIS (How do the light dependent and light independent reactions provide food for a plant?) Why? How important are plants to life on Earth? Could life as we know it continue if there were no plants? Read on the find out why plants are truly the cornerstone of life.

ASSIGNMENT: 1 SESSION: 2012/13 TUTOR: Stuart Allan WORD COUNT: 1‚891 Carbon fibre is a strong‚ yet light‚ reinforced polymer. Carbon fibres are used in applications where high strength and light weight are required. Carbon fibres can also be easily moulded into the desired shape. They are also chemically inert‚ resistant to heat‚ and do not expand under changing temperatures. Machining of carbon fibre materials can generate airborne particles. The potential health effects of

Photosynthesis is a process done in the chloroplasts of plant cells that is beneficial to all of life. Plants are able to convert light to energy which is beneficial to the plants‚ while also giving off oxygen as a byproduct for humans. Chloroplasts are in the thylakoid discs of a plant cell‚ that contain chlorophyll a and chlorophyll b‚ which are it’s light-capturing pigments. Colors in the wavelengths are either absorbed or reflected by the chlorophyll in which case green is reflected and colors
