Photosynthesis is one of the most important of biological processes on earth. Explain the process of photosynthesis in words, describing the components which plants take in and which are produced.

Back 15

Plants take up carbon dioxide from the atmosphere and water from the soil and use sunlight to split water into hydrogen and oxygen. The hydrogen is then used to join with carbon dioxide in the air to form carbohydrates, with byproducts of water and oxygen.

Front 16

Describe the strategies that plants have evolved for collecting light and water

Back 16

Light: Some plants compete for sunlight by growing into towering trees. Smaller plants beneath the canopy either fail to thrive or simply die. I this way plants compete for light.

Water uptake: Roots have specialized root hairs to ensure that every drop of water is taken up. Through a set of tubing knows as xylem, water is brought to every leaf through the process of transpiration.

We measure energy uptake in humans in terms of calories. Describe how a calorie is measured (include the name of the device used,) how a small excess of calories per day can lead to obesity over a lifetime, the statistics of obesity as a cause of death in 2000, and 3 major health consquences of obesity

Back 46

Calorie is measured using a Calorimeter as is defined as the amount of heat energy that raises one kg of water by 1C.



As little as 40-50 extra calories a day can cause you to gain about 1 pound per year. Over the course of a lifetime, an individual may gain many pounds to the point of obesity.



In the year 2000, obesity accounted for approximately 400,000 deaths in the United States, second only to smoking-related death.



Any of the following 3: heart diseases, stroke, adult onset diabetes, high cholesterol, osteoarthritis, and certain types of cancer

How is the energy released from the sun produces and how long will this reaction continue for?

Back 47

Within the sun, at its core, nuclear fusion is occurring. At a temperature of 28 million degrees, hydrogen atoms are combined to form helium, releasing huge amounts of energy which reach the earth in the form of light and heat. This reaction in the sun has been occurring for 5 billion year and will continue to occur for another 5 billion years.

Explain how energy originates in the sun and how that energy, once it reaches Earth, is transferred through the food chain.
