Effect of Light Intensity on the Rate of Photosynthesis

Purpose
The purpose of this experiment was to determine how light intensity affects rate of photosynthesis using seaweed.
Introduction
In the process of photosynthesis there is combination of water and CO2 from the environment to form oxygen and sugar, mainly glucose (Emeritus, 2010). These products are then used by the plant through the process of respiration producing water and carbon dioxide (Seeley, Stephens, & Tate, 2004).

Hypothesis

It was hypothesized that the rate of photosynthesis as measured by the number of bubbles produced increased as light intensity increased.

Methods

Results
The amount of bubbles that appeared during the ...

Investigating how light intensity will affect the rate of photosynthesis, with the help of DCPIP, in Spinach leaves.

The aim of this experiment is to find out how the rate of change of light intensity affect the photosynthesis in spinach leaves.
Successful farming of food crops is very essential for both the nutritional and financial health of a nation. Governments of almost every nation invest land and labour to crop farming, as much as is possible, keeping in mind the other needs of a country. But, however, due to many reasons the maximum crop yield possible is not always achieved.
For the production of a healthy crop certain conditions are necessary. The primary among these conditions are ...

Photosynthesis/Semiconductor-based solar cell

Photosynthesis is a process where plants manufacture carbohydrates from water, carbon dioxide and minerals with the use of light as an energy source. Plants degenerate water and carbon dioxide into carbon, hydrogen and oxygen which form glucose, the source of energy for plants that helps in food production and growth. A semiconductor-based solar panel is used to harness solar energy into electricity form. People can use this device to harvest sunlight energy and use it as electricity.

Solar cells and plant cells use sunlight and change it into energy. The process by which sunlight is converted into energy differs though. ...

Executive Summary

This process of making 17 reams release 100 pounds of Carbon dioxide in the environment. Forests and trees are mainly responsible for maintaining a stable environment of the world. Going paperless will help reduce the total waste that disturbs the natural environment. Trees are naturally responsible for absorbing carbon dioxide through the process of photosynthesis. The amount of paper recycled is proportional to the amount of tree saved. The increased usage of recycled paper will help decrease the demand for virgin paper. Decrease in the demand of virgin paper will automatically help reduce the air and water pollution. The paper ...

Dissolved oxygen is believed to be the volume of oxygen in water. Dissolved Oxygen is believed to be part of the microscopic bubbles of oxygen which are normally mingled water and then appears to occur among water molecules. This component is a vital index of the water body's power to back aquatic life. Aquatic animals and other species like fish "breathe" by absorbing the available dissolved oxygen by means of their gills.
The gaseous oxygen comes in the water by absorption straight from the air or by aquatic plant and algae photosynthesis. The dissolved oxygen is believed to be ...

Carbon (C) is a chemical element of atomic number 6 and belongs to group 14 on the periodic table. Carbon is a nonmetallic element and it’s the sixth in abundance in the universe. Coal is the most readily available source of carbon. Carbon in its raw form is of little value and has to be processed into commercially applicable forms. Commercial carbon appears in three allotropes: graphite, amorphous, and diamond. This is a research paper on carbon, its applications and negatives effects on the environment (Jefferson Lab).

CARBON ALLOTROPES

Amorphous carbon is the resulting black material when a carbonaceous fuel or compound is burnt ...

Introduction

Biomass is a biological material obtained from a living organism or a recently living organism. The word biomass is derived from two Greek words; bio meaning life, and maza meaning mass (Demirbas, “Fuels from Biomass” 43). Biomass means non-fossil and bio-decomposable organic matter (originating from plants, animals and microorganisms). The products, byproducts, residues and waste from agricultural processing, all constitute biomass. Bio-waste simply means non-fossil and biodegradable waste that is composed of organic matter. Bio-wastes include food and kitchen wastes, garden and park wastes, and wastes from food processing plants. Bio-waste is therefore an element of biomass.
Non-fossil wastes that are ...

Introduction

The pollution in the highly urbanized areas allows the phenomenon called ‘greenhouse effect’ wherein the heat from the Sun is trapped on the land causing tremendous amounts of heat and leads to numerous issues such as the rise of temperature, drought, the melting of icebergs, and high evaporation of water. Unfortunately, the cities contribute to this effect, the use products containing CFC’s and the pollution of too much carbon dioxide in the atmosphere leads to the destruction of the ozone layers. With the destruction of the atmospheric barrier, the excessive radiation from the sun cannot be prevented. In ...

Research Question: Does a diet such as low fat and low cholesterol really help lower LDL? Hypothesis: It may or may not. Early research sometimes suggested not eating eggs would help lower cholesterol. This resulted in limits for how many eggs one should eat, if any. Determine if a low fat and low cholesterol diet really works with the study outlined below .
Compare two groups of patients: one group eliminating foods which may alter LDL levels and one which continues on with their usual diet before diagnosis of the high LDL levels. Foods to be considered are eggs, 2% ...

Sun plays crucial role in the life of the Earth. The entire organic world of our planet is obliged to the Sun for its existence. It is not only the source of light and heat, but also the original source of many other types of energy (oil, coal, water, wind). Since people appeared on the Earth, they began using the sun's energy. According to archaeological data, it is known that housing preference was given to quiet places, closed from the cold winds and open to the sun's rays.
Perhaps the earliest known solar system can be considered the ...

The transition from aquatic to terrestrial habitat no doubt posed some challenges to plants. They have had to overcome challenges in order to adapt completely to life on land. Some of the challenges that that plants faced by moving from water to land was the problem of water loss. They also had to overcome the challenge of reproduction. Also, terrestrial plants have had to evolve new ways of feeding. Some of these are presented below.
The evolution of plants to terrestrial habitat took place from their ancestors which were algae. Algae had to adapt to living in shallow ...

Introduction

Stomata are sections in plants leaves that regulate the amount of water vapor and gases entering in and out of green plant leaves. Stomata are very essential in the control of water loss through the plant leaves in a process of transpiration. In light plants, transpiration is highest in the presence of sunlight because the guard cells fully open the stomata. Dark plants use the inverted stomatal rhythm and the openings of the stomata are wider in the dark. The opening of the stomata in leaves increases with time: at the beginning, fewer are open but after sometime majority become ...
