history goes the lights have been around for a while which is known because researchers have found cave painting that go back to around 30‚000 years ago. The lights were originally understood to be a harbinger for destruction or for war (1). This was thought to be until they found out what caused the lights. Many astronomers‚ philosophers and authors refer to the lights in their work. Some of these people include Goethe‚ Aristotle‚ Descartes‚ and Halley (1). In 1616‚ the lights were called aurora

Title: The success of photosynthesis in geranium leaves using visible light wavelengths obstructed by black paper‚ and red‚ blue‚ and green translucent filters. I. Abstract Photosynthesis is a process in which plants use light‚ water‚ and carbon dioxide to produce sugars‚ water and oxygen. Chlorophyll a and chlorophyll b‚ in the chloroplasts of a leaf‚ are responsible for absorbing wavelengths of light for use in photosynthesis with red and blue wavelengths being optimal. Testing

The case of the Phoenix Lights is one of the intriguing and controversial UFO sightings on records. On the evening of March 13‚ 1997‚ thousands of people were outside waiting to see the spectacular Hale-Bopp Comet‚ until thousands of eyewitnesses reportedly seeing mysterious dots of lights spotted in the sky hovering over Phoenix‚ Arizona as the Hale-Bopp Comet passed over the sky. Thousands of eyewitnesses stated to have seen what is believed to be bright dots of lights that is a spacecraft formed

Answers to Photosynthesis Practice AP Biology 1. Draw a picture of the chloroplast and label the stroma‚ thylakoid‚ thylakoid lumen (space)‚ inner membrane‚ outer membrane. 2. Using 18O as the basis of your discussion‚ explain how we know that the oxygen released in photosynthesis comes from water. When the oxygen in water has the radioactively labeled oxygen‚ the gas released from photosynthesis also has the labeled oxygen. This shows that the oxygen gas given off during photosynthesis comes from

needed for photosynthesis. The process of photosynthesis occurs in all plants‚ plants absorb sunlight through the leaves using the chlorophyll pigments in the leaf cells. The carbon dioxide diffuses through the stomata‚ under the leaf. The roots of the plants absorb the water from the soil and then the xylem will transport the water and nutrients upward to the leaves. As well as that the roots also store nutrients and anchor the plant. Plants also need Nitrogen to allow them to photosynthesis. Plants

Photosynthesis depends on an interaction between two sets of reactions: the light reactions and the Calvin cycle. Chlorophyll and the other molecules responsible for the light reactions are built into the thylakoid membranes. The enzymes that catalyze the Calvin cycle are located in the stroma. Beginning with the absorption of light by chlorophyll‚ the light reactions convert light energy into chemical energy in the form of ATP and NADPH. The ATP provides the energy‚ and the NADPH supplies the electrons
