This experiment is set up the study the effect of different sodium bicarbonate concentrations on the rate of photosynthesis in spinach (Spinacia oleracea). Photosynthesis is the process by which plants and other photoautotrophs synthesize organic compounds from carbon dioxide (Faculty of Science and Horticulture, 2018). Photosynthesis takes place in the chloroplast of a plant cell, where sunlight, water, and carbon dioxide are used in a reaction to produce oxygen and sugar (Reese 2017). In the photosynthesis reaction carbon dioxide is reduced to make sugar and water is oxidized to make oxygen. In this experiment oxygen production is being used to measure the rate of photosynthesis.
The scientific name is Elodea Canadensis (Ashley, 2000). This experiment will look at the effect of light intensity on the rate of photosynthesis in Elodea plants. Aim The aim of this experiment is to examine the effect of light intensity on the rate of photosynthesis. Hypothesis The rate of photosynthesis is directly proportional to light intensity but inversely proportional to
Research Question: How does the presence of light impact the rate of transpiration in plants? Aim: The aim of this experiment was to investigate how the presence of light affects the rate of transpiration in plants. Hypothesis: As light intensity increases, the rate of transpiration (water uptake) in a plant increases. Background Information: In this experiment I will be investigating the impact of light intensity on the rate of water uptake, due to transpiration, by attaching a shoot from a leafy plant in the capillary tube of a potometer, and then measuring how long it takes for a bubble to move a set distance. The faster the bubble moves, the greater the rate of transpiration.
The Development and Testing of Greenhouse Comprehensive Environment Control System Mohammed Alrefaie and Yaser Miaji .. Abstract- Greenhouses provide a convenient means to grow plants in the best environment. They achieve this by trapping heat from the sunlight and using artificial means to enhance the environment of the greenhouse. This includes controlling factors such as air flow, light intensity and amount of water among others that can have a big impact on plant growth. The aim of the greenhouse is to give maximum yield from plants possible. This report details the development and testing of greenhouse environment control system that can regulate light intensity.
Cell Respiration Lab Research Question What is the optimal temperature for germinating pea-seeds where the rate of respiration is the greatest? Background Information Cell Respiration refers to the biochemical process conducted by the cells of an organism that combines glucose and oxygen to produce energy in the form of ATP, along with two by-products, water and carbon dioxide. The equation representing this chemical reaction is shown below. C6H12O6 + 6 O2 6 CO2 + 6 H2O + ATP Although plants and animals have different methods of obtaining glucose, the cell respiration process occurs in both types of organisms. Many external factors in the environment may affect the organism's’ rate of respiration such as the temperature of the surrounding,
Title Which frequencies and type of light aided and affected the efficiency of photosynthesis or carbon dioxide consumption in a spinach leaf? Purpose The purpose of the experiment/lab was to observe the effectiveness of different lights during the process of photosynthesis. Background Photosynthesis is a biological process. It occurs in plants, algae and specified bacteria (prokaryotes). Photosynthesis is the process where plants, algae, and bacteria convert light energy into chemical energy.
However higher intensity have a better effect on the rate of photosynthesis, as it manages to hit not only the top part of the plant but also the bottom leaves, maximizing the effects of photosynthesis to the plants potential. Farmers use the power of grow lights to control the photoperiod during the seasons where sunlight isn’t as strong and photoperiod is lower and to increase the rate of photosynthesis. There are different kinds of grow light and each of them has different function or a different effectiveness: • Incandescent; The incandescent light bulb is used to control photoperiod mostly. This because the majority of energy form released from the light bulbs is heat rather than light, and is therefore an inefficient light source. Also because this light bulb releases mostly heat it must be placed at a correct distance from the plant, otherwise it might cause the plant to burn.
Antireflection coating became an integral part of designing different types of solar cells. Reflections can be minimized in certain wavelengths thus result in higher overall efficiency. In order to understand the working principle behind antireflection coatings, we must first understand the nature of light and it’s interaction with other materials. It is of utmost importance for solar cell designers and researchers to understand both the particle and wave nature of light in order to design a high efficiency solar cell. The Sun’s energy which radiates into the Earth’s surface and harnessed by solar cells are composed of broad spectrum of electro-magnetic (EM) waves combined together which form visible light that have different power densities depending on the wavelength of propagation.
Plants go through a process called photosynthesis. Photosynthesis is the process in which water, carbon dioxide, and light create oxygen and glucose for plants to grow. Water and light go through light dependent reactions. In the light dependent reactions, ADP and NADP+ are converted into ATP and NADPH, which are energy carriers. The product of light dependent reactions is oxygen, which they release some into the air and use some for cellular respiration.
They harness their energy form the sun to carry out photosynthesis (Miller and Levine) However, other things are needed to do photosynthesis as well. Carbon dioxide and water are the key components to process photosynthesis. Chloroplast makes photosynthesis happen. They are organelle, or a specialized structure that performs important task in the plant cell. Cell in the plants co-operate to help
