tubes was tested. The solutions in the opaque tubes were placed on a slide with a drop of blood and observed under a microscope and compared to a control slide with just a drop of blood. Sketches of the observations were made and analyzed. A leaf of Elodea was placed on a slide along with solution X‚ observed‚ and drawn. Solution Y was then drawn through the slide and the previous method was repeated. The same was done with solution Z. The results were gathered and

Write the equation for photosynthesis: Photosynthesis occurs in the chloroplast‚ an organelle in plant cells that contains the molecule chlorophyll

Factors Affecting Photosynthesis Low light intensity lowers the rate of photosynthesis. As the intensity is increased the rate also increases. However‚ after reaching an intensity of 10‚000 lux (lux is the unit for measuring light intensity) there is no effect on the rate. Very high intensity may‚ in fact‚ slow down the rate as it bleaches the chlorophyll. Normal sunlight (usually with an intensity of about 100‚000 lux) is quite sufficient for a normal rate of photosynthesis. Open and Closed

first ensure that the ecosystem’s foundation is remaining strong‚ a foundation known as photosynthesis. When photosynthesis is functioning as it should‚ in its fullest capacity‚ all organisms benefit from it in some way. Furthermore‚ scientists aim to better understand the photosynthetic process to help enhance the efficiency and quality of life on Earth. By fully understanding the function of photosynthesis‚ some environmental adjustments can then be made to refine the photosynthetic process. In

"if" or "than" are also used though less commonly. A simile differs from a metaphor in that the latter compares two unlike things by saying that the one thing is the other thing. Using ’like’ A simile can explicitly provide the basis of a comparison or leave this basis implicit. In the implicit case‚ characterized

Photosynthesis Green plants absorb light energy using chlorophyll in their leaves. They use it to react carbon dioxide with water to make a sugar called glucose. The glucose is used in respiration‚ or converted into starch and stored. Oxygen is produced as a by-product. This process is called photosynthesis. Temperature‚ carbon dioxide concentration and light intensity are factors that can limit the rate of photosynthesis. Photosynthesis summary Photosynthesis [photosynthesis: The chemical change

Bubbling Cabomba pondweed Teaching Notes Introduction Like many other water plants‚ Cabomba has specialised tissue called aerenchyma that allows gases to diffuse inside the plant. Aerenchyma provide buoyancy and allows oxygen transport to the submerged roots that may otherwise be in hypoxic (low oxygen) conditions. If you cut through the aerenchyma‚ oxygen can escape. This can be made use of this in the classroom to show how the rate of photosynthesis is affected by light intensity or by

PHOTOSYNTHESIS LAB Alyssa Wright VARIABLE: LIGHT INTENSITY AIM: to investigate the effect of light intensity (lux) on the amount of oxygen produced (number of bubbles) HYPOTHESIS: I predict that the rate of oxygen produced increases‚ as the light intensity increases‚ but only to a point. I predict this will happen because the plant will have enough carbon dioxide and water to keep up with the amount of light that there is. When there is less light intensity‚ photosynthesis will happen

Jeanette Jones Biology Period:2nd Research Essay #2 Photosynthesis is a very beneficial process. It consists of products that are an good impact on different things like its impact on species. Plants are important in regards to everything living and everything period. One way I believe photosynthesis is most beneficial in its relation to species. All living things go through a process. Plants in particular are very important
