position. *Round Rf values to 2 decimal places CONCLUSION: We used paper chromatography to separate the pigments found in spinach. Since plants use several different pigments to capture light energy for the light dependent reaction in photosynthesis, we expected that we would see several different bands of pigments on our chromatography paper. As the data in Table 1 indicates, we obtained four bands of different pigments from the spinach leaf: yellow- brown, light green, green, and yellow

to dehydration of vegetation. Flooding can cause the nutrients to be washed away as well as smother the plant roots. High light intensity could cause irreparable damage to the leaves due to radiation where as low light intensity could inhibit photosynthesis. Under freezing conditions, water will turn to ice which prevents the plant from absorbing it. Also, as water becomes ice, the volume will expand and can cause physical damage to the plant itself. High temperatures increases evaporation of water

5.4.1 Outline the processes of eutrophication Include increase in nitrates and phosphates leading to rapid growth of algae, accumulation of dead organic matter, high rate of decomposition and lack of oxygen. The role of positive feedback should be noted in these processes. Eutrophication can have a devastating effect on rivers and streams. Normally nutrients such as nitrogen, phosphorous and potassium limit plant growth. Human inputs of these fertilizers into water systems cause rapid plant

producer, first-order consumer, and second-order consumer. In the diagram of the food chain, the arrows show how energy flows from one level to another. The green plants are the producers because they food are produced by the process of photosynthesis by using sunlight, water and carbon of the food chain. The second order consumers are carnivores because the herbivores are their food. Therefore, carnivores are in the second-order consumer because they depend on the first-order consumer to produce

Algae - Wikipedia, the free encyclopedia Page 1 of 13 Algae From Wikipedia, the free encyclopedia Algae (/ˈældʒiː/ or /ˈælɡiː/; singular alga /ˈælɡə/, Latin for "seaweed") are a very large and diverse group of eukaryotic organisms, ranging from unicellular genera such as Chlorella and the diatoms to multicellular forms such as the giant kelp, a large brown alga that may grow up to 50 meters in length. Most are autotrophic and lack many of the distinct cell and tissue types found in land

Internet National Geographic Researchers(2011) High level of CO2 Global warming is caused by the emission of greenhouse gases. 72% of the totally emitted greenhouse gases is carbon dioxide (CO2). Carbon dioxide emissions therefore are the most important cause of global warming. The emissions of CO2 have been dramatically increased within the last 50 years and are still increasing by almost 3% each year I.A.1

Cells of all organisms are capable in acquiring the energy necessary to fuel chemical reactions for growth, repair, survival, and reproduction. Photosynthesis & cellular respiration are the main pathways of energy flow in living things. Photosynthesis is a process by which plants and some other organisms convert, light energy from the sun, CO2 from the air & H2O from the earth, into chemical energy stored in molecules like glucose. Cellular respiration is a process in which O2 is delivered

by itself won’t make the plant green, it just switches the sunlight into energy, to make the plant greener you need a pigment called chlorophyll, chlorophyll is a pigment that provides the absorption of light to provide energy to make it into photosynthesis and that causes a chemical change to the plant. Why do our muscles ache when we exercise? The reason muscles ache after exercising is because you just stretched out your muscles fibers and your muscles are about to enter the repairing

Biology: Concepts and Connections, 6e (Campbell) Chapter 7 Photosynthesis: Using Light to Make Food Multiple-Choice Questions 1) The summary equation for photosynthesis is A) 6 CO2 + 6 H2O + sunlight → C6H12O6 + 6 O2. B) C5H12O6 + 6 O2 + sunlight → 5 CO2 + 6 H2O. C) C6H12O6 + 6 O2 + sunlight → 6 CO2 + 6 H2O. D) the same as the equation for glycolysis written in reverse. E) 6 CH2O + 5 O2 + sunlight → CO2 + 2 H2O.
