An Investigation into the Effect of Light Intensity on the Rate of Photosynthesis on a Piece of Elodea Plan: Method: 1) First I will put some water into a boiling tube and add 5 spatulas of Sodium Hydrogen Carbonate. I will add 5 spatulas of Sodium Hydrogen Carbonate as it reacts with water and forms carbon dioxide; also I have so much so that I have carbon dioxide in excess. 2) Then I will cut off 5cm of elodea and place it into the boiling tube. 3) Thirdly I will place the boiling
Photosynthesis Investigation to find effects of distance of a light source from pond weed has on the amount of oxygen produced Photosynthesis All green plants need to be able to make their own food.They do this by a process called photosynthesis.For photosynthesis to occur they need sunlight energy.This energy is absorbed by a green pigment called chlorophyll,which is mainly found in the leaves.This energy then combinEs with water molecules (from the soil) and carbon dioxide (from the air).Then
Investigation Into the Colour of Light Needed to Start a Photosynthesis Reaction Diagrams [IMAGE] Method The apparatus for this experiment will be setup as shown in the diagram, for all the experiments the coloured filter will be 5cm away from the white light bulb, which is a 60watt bulb, and the beaker will be 20cm away from the edge of the coloured filter. Just before the experiment takes place we will place the pond weed (which has been in darkness for at least 24 hours to stop
Photosynthesis is the process of making glucose using the raw materials water, carbon dioxide and radiant energy. Which is trapped by the chlorophyll molecules and then oxygen is given off as a bi-product if the process. It is the conversion of radiant energy into chemical potential energy. The occurrence of photosynthesis is very important to us as humans, because it provides us with the oxygen we need to breathe and plants are at the bottom of every food-chain and so without them, I would collapse
would increase as the light intensity decreases. Therefore, plantain leaves found in the shade will have larger surface areas than leaves found in an open area. Theory: Sunlight is an essential factor need to complete the process of photosynthesis. Photosynthesis consists of the following equation: Sun light Carbon dioxide + Water ========> Glucose + Oxygen Chlorophyll Chlorophyll is a substance found in chloroplasts, found in the cells of leaves. They are used to produce glucose which
Temperature on the Rate of Photosynthesis Aim The aim of my experiment is to determine whether intensity of light and temperature would affect the rate of photosynthesis in a plant. To do this, I will place a piece of pondweed in varying light intensities and temperatures, and observe the amount of oxygen being given off. I am using pondweed because of its unusual quality of giving off bubbles of gas from a cut end, when placed in water. Introduction Photosynthesis occurs only in the presence
The investigation was completed over a period of a week for a wide range in the results to base experimental conclusions. From the primary data obtained, the pattern of the results supported the hypothesis and followed the trends of the theory discussed earlier and also the reflection spectra (Figure 2). The vertical growth of height table and graph (Table 1 & Figure 3) demonstrates the effects isolated colours of light have on the vertical growth of plants via mung beans. In the experiment of this
The Effect of Light Intensity on Photosynthesis Of Elodea Canadensis Introduction I wanted to find out how much the light intensity affected the Photosynthesis in Elodea Camadensa. I decided to do this by measuring the amount of oxygen created during photosynthesis. Photosynthesis is the procedure all plants go through to make food. This process uses Carbon dioxide, water and light energy. It produces Oxygen and Glucose. [IMAGE]Carbon dioxide + water Light Energy glucose + oxygen
stomata is between these two specific types of leaves. Stomata is found on the epidermis of the plant and works hand in hand with water levels in the plant, stomata’s purpose is to absorb carbon dioxide to release oxygen which all falls into photosynthesis as well as assisting
plant. Plants use xylem vessels, which are vertically elongated vessels with lignified walls, to transport water and dissolved minerals from the roots to the leaves, where they can be used for photosynthesis and cell growth (Roberts, King, 1987). Phloem vessels transport carbohydrates, created during photosynthesis, from the leaves to the rest of the plant to be used in growth (Whiting, 2010). Plants also use transpiration as an evaporative cooling system. This is possible because the process of evaporation
Plant Location Lab Background: This investigation involves with dependents of plants around the world growing constantly. Recently, plants have been growing at a slow ate without any sunlight. According to scientists, plants are now growing without light and effects the development stages. The longer the measurement of the seeds to bloom, the longer the estimating growth rates between 2 weeks to 2 months to evolve. Scientists pointing out saying that plants will grow rapidly without sunlight. The
Our world is filled with beautiful plants of all different colours. Green is clearly the most prominent colour, and we know that this is due to the presence of chlorophyll. We have also learnt that photosynthesis is a vital process that occurs in order to create glucose and oxygen, by transforming carbon dioxide and water in the presence of light energy. Chlorophyll is vital for this process due to the fact that the light energy which allows for this process to occur is trapped in the chlorophyll
Photosynthesis Investigation Research Question How does the concentration of glucose affects the photosynthesis rate of a spinach leaf when exposed to a LED light source? Hypothesis My hypothesis is that when the concentration of glucose is glucose increasing the faster the rate of photosynthesis will occur.The LED light will make the photosynthesis work even faster so the spinach leaves will probably go up faster than normal.I think that the glucose will help the rate of photosynthesis because
excellent covering for buildings. Its leaves and berries are poisonous. English ivy belongs to the ginseng family, Araliaceae. The scientific classification would be Hedera helix. Being an evergreen plant it has the advantage of being able to photosynthesis during the winter months whereas deciduous trees are dormant. The increased light that is available, by the absence of deciduous leaves allow it to grow more rapidly up the trunk of the host tree. The evergreen leaves of the plant also inhibit
minutes, the reading was taken for 40 minutes. Finally the lamp was turned off. Following the experiment, the results were entered into an Excel spreadsheet. Using the online t-test software “graphpad”, an unpaired t-test was generated. In this investigation the light intensity, and temperature, and aquatic plant (Elodea densa) were constant, and thus where the control variables. (Rush,
Light Intensity's Effect on Photosynthesis Aim : To find out how light intensity will affect the rate of photosynthesis in a piece of Canadian Pondweed. Prediction : I predict that as I increase the distance between the light source and the Canadian Pondweed (reducing the light intensity), the volume of oxygen produced within the time limit (the measure of the rate of photosynthesis) will decrease. This will happen because as the light source is moved further away, less light rays will
particular morphological feature that was going to be investigated. It was felt that the best possible use was made of the equipment and sites available in order to attain reliable data under the time constraints involved. The sample size for this investigation was set at 30 – this allowed a reasonably large sample and thus reasonably confident conclusions and tests are possible for the Analysis and Evaluation sections. However, a sample size of 30 is still small enough in order to feasibly collect data
required to drive photosynthesis, the photosynthetic machinery can only tolerate so much of it. Excess light may lead to the generation of reactive oxygen intermediates resulting in oxidative damage to the photosynthetic apparatus (Niyogi, 1999). Therefore it is necessary for organisms such as the green algae Chlamydomonas reinhardtii to employ photoprotective mechanisms in order to maintain photosynthetic efficiency and reduce stress caused by excess light. During photosynthesis, solar energy in
Investigating the Relationship Between the Transpiration Rate of a Shoot and the Degree of Opening of the Stomata of Its Leaves I will be investigating the relationship between the transpiration rate of a shoot and the degree of opening of the stomata of its leaves. Transpiration is the loss of water vapour from the surfaces of a plant. Solar energy turns the water in the plants into a vapour causing it to evaporate into the leafÂ’s internal air spaces before diffusing out of the stomata

Still, the study shows effects of TiO2 and N-TiO2 on Melissa officinalis, but to understand the positive and negative effects of nanoparticles on other physiological characteristics of Melissa Officinalis requires further investigation. It is necessary to examine aspects of its growth affected of nanoparticles and then release to market. Because, lemon balm plant is known among people and its use is very common as a food and medicine, particularly in traditional societies.
