Through this experiment‚ Egeria densa was observed using a microscope. The task was to observe and identify the different types of cell‚ cytoplasmic streaming‚ and plasmolysis of Egeria densa. First‚ the microscope was examined and investigated to master the use of the equipment. A microscope slide grid which was on the slide glass was required to be seen clearly using 4x‚ 10x and 30x. During the latter part of the experiment‚ the Egeria densa was observed using the microscope to understand the

“Investigate how light and darkness contribute to the cycling of carbon through both cellular respiration and photosynthesis of a plant” we devised a hypothesis that states‚ If we place the two test tube‚ one with carbonated water and the other regular water‚ with the Elodea inside a dark environment it will perform cellular respiration as it will not receive enough light energy to perform photosynthesis. From the result of our experiment we found that the test tube with tap water and Elodea changed from

The purpose of the experiment is to determine the effects of sugar on photosynthesis in Elodea. Sugar water with Elodea‚ water with Elodea‚ and water (control) are used to test for photosynthesis. Five drops of sugar water were added to sugar water with Elodea beaker. The three beakers were left under normal light for photosynthesis to occur. After 60 minutes‚ NaOH solution was added to each beaker to test the volume of CO2. The result shows that both Sugar water with Elodea and water with Elodea

Photosynthesis Background Do you know what is the most important process that sustains life? Photosynthesis‚ that is the correct answer! Photosynthesis‚ is known as the process to produce plant food. But‚ how does is the life exist on the planet we call our home‚ Earth? Photosynthesis is a process that we know that allows water‚ carbon dioxide‚ and some mineral salts along with the light from the sun to make glucose (sugar). During the process‚ the root sytem of the plant takes in elements

wavelength of light on the rate of photosynthesis was investigated in this experiment. The results from Figure 13 suggest that white light‚ containing all wavelengths of coloured light‚ has the highest rate of photosynthesis. Purple light had the second highest efficiency‚ followed by blue‚ red‚ and yellow light. Green light was significantly less efficient‚ producing the second lowest pH reading (Figure 14). The samples exposed to no light had the lowest rate of photosynthesis. The hypothesis that white

Abstract: The rate of photosynthesis and cellular respiration can change in varying conditions. How does the rate change with varying degrees of temperature and light exposure? To test this algae beads were exposed to a CO2 indicator‚ which changes colors based on the level CO2 level present. The algae beads were exposed to two different variables‚ light and temperature and tested for color change‚ Ph‚ level‚ and CO2 absorbance level. The beads were exposed to a light and a dark condition‚ and another
Premium Photosynthesis Carbon dioxide Oxygen
Introduction Photosynthesis is a well perceived performance in which plants and other defined organisms use the energy of photons to convert carbon dioxide and water into a simple monosaccharide sugar known as glucose. Photosynthesis provides the fundamental energy source for essentially all living organisms. The most substantial and valuable byproduct of photosynthesis is oxygen‚ one of the most abundant elements living organisms depend on. Photosynthesis occurs in many organisms

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

The purpose of this lab was to investigate whether veins affect photosynthesis rate. It was predicted that having veins would decrease the rate because chloroplast might be less frequent due to the vascular tissue. For this experiment‚ 4 groups were set up: veins and no veins in CO2 solution‚ and veins and no veins in distilled water‚ the distilled water groups served as controls. These 4 groups were placed under a light bulb in order for photosynthesis to occur. No disks experience movement in the
