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
Premium Light Photosynthesis Energy
Hypothesis: I predict that the leaves taken from the outer area of a shrub have a higher stomatal index (/density) than those taken from the centre of a shrub this are due to light levels. Explanation: Plants have stomata to obtain carbon dioxide from the atmosphere and remove oxygen produced in photosynthesis. During photosynthesis the chloroplasts in the leaf cells synthesize as a result of exposure to light‚ while oxygen is produced as a by-product. As the outer leafs are exposed to higher light

This evidence refutes the long standing hypothesis that A human red blood cell in an artery of the left arm is on its way to deliver O2 to a cell in the thumb. From this point in the artery‚ how many capillary beds must this red blood cell pass through before it returns to the left ventricle of

called photosynthesis. This process assists in nourishing plants and keeping them alive. For example‚ trees grow very tall in the rainforest where there is an abundance of water in order to reach as much light as they can. For this reason‚ in order to survive the chloroplast in plants must capture light energy from the sun and convert it into chemical energy that is stored in sugar and other organic molecules (Photosynthesis‚ 2014‚ p. 185). In plants that contain chlorophyll‚ the photosynthesis process

currently consists of approximately 0.04% of Carbon dioxide. A large proportion of it is found dissolved in the oceans as well as the atmosphere. The carbon cycle consists of 6 stages. Initially the CO2 that is absorbed by plants for the use in photosynthesis becomes carbon compounds in plant tissue. The carbon is moved up the food chain by consumption‚ a primary consumer. It is passed on to the secondary and tertiary consumers when they eat other consumers. When these organisms die they are digested

Cellular Respiration Purpose The purpose of this experiment was to determine the effect of body mass and temperature on the rate of respiration in the mouse. Hypothesis When the temperature is reduced‚ cellular respiration will increase. Measurement Weight the mouse and use soda lime for mouse to perspire. Oxygen was inhaled and carbon dioxide was exhaled. Carbon dioxide was absorbed by soda lime. Rate of respiration was measured in terms of ml of oxygen per min over grams. General
