Transpiration Formal Lab Report By Jessica Tran Introduction When water is transported from the roots to the mesophyll cells in the leaves‚ it is evaporates out the stomates‚ called transpiration‚ to create a lower osmotic potential. Osmotic potential is the part of the water potential of a tissue that results from the presence of solute particles. Even though the stomates open to release water‚ it also brings in carbon dioxide to produce sugar and oxygen through a process of photosynthesis. The water

The correlation between the occurrence of photosynthesis and different lengths of light waves. Introduction Photosynthesis is an exceptionally interesting process that is used by some organisms and plants. In the conversion of light energy from the sun to chemical energy that is used as food‚ photosynthesis is used for the everyday undertakings by some organisms and plants during their life span. This complex method of energy production is also represented by the equation: 6CO2 + 6H2O C6H12O6

Chlorophyll Extraction This easy science project shows simple and efficient method of chlorophyll extraction from a plant. This is only a demonstration of working method which can be refined and used for a full scale science project. Plants contain many pigments in different proportions. For flowering plants it’s mostly a combination of chlorophyll-A‚ chlorophyll-B‚ pheophytin and Carotenes. These pigments have shades of green‚ blue green‚ grayish‚ and yellow-orange. Their concentration is

Introduction The aim of this practical 1 is to determine the rate of photosynthesis by measuring the rate of oxygen production‚ which is a direct consequence of PSII activity. Results Graph 1 Graph 2 Discussion i. It took 2 minutes before any increase in the O2 concentration of the chamber was observed‚ it took 2minutes‚ after illuminating the leaf. ii. There are 2 main parts of the photosynthesis‚ light dependent part and light independent part‚ the O2 is released in last part which is light-independent

Plant Pigments and Photosynthesis Problem: We are going to separate and identify pigments and other molecules from cell extracts through a process called chromatography. We will also test the theory that light and chloroplasts are required for light reactions to occur. Background: Pigments are chemical compounds which reflect only certain wavelengths of visible light. This is what makes them seem colorful. Many things contain pigments including flowers‚ corals‚ and even skin. More important than

increased‚ the average rate of photosynthesis of the leaf discs increased in a linear trend. As it is the sodium bicarbonate which decomposes into carbon dioxide necessary for photosynthesis‚ it is reasonable to consider from Graph 1 that as carbon dioxide concentration of the solution increases‚ the rate of photosynthesis will also increase in a linear trend. Carbon dioxide concentration is shown to be directly proportional to rate of photosynthesis ([CO2] ∝ rate of photosynthesis). The line of best fit

Introduction Photosynthesis is the process by which autotrophic organisms convert light energy to chemical energy in the form of glucose. Without this process life on earth would be very different because every organism directly or indirectly depends on photosynthesis. Photosynthesis helps the plants to grow roots‚ leaves‚ flowers and fruits. It is an extremely important process because plant tissue serves as the bottom of every food chain. The process of photosynthesis is dictated by a number
