Aim: To investigate how sugar concentration affects the mass or size of a potato and find out the sugar solution.
Introduction: Osmosis is the movement of water molecules across a partially permeable membrane form a region of high water concentration to a region of low
The effects of different wavelengths of light on the rate of photosynthesis
This experiment was performed to investigate the effects of different wavelengths of light on the rate of photosynthesis. If a multiple colored film petri dishes are place under a 50 watt lamp, then the rat
To survive, all organisms need energy. Plants get most of their energy from photosynthesis. Plants are autotrophs, that generate their own chemical energy from the product of the sun through photosynthesis. The chemical energy that plants get from the sun is used to produce gluco
In photosynthesis, light energy is transformed into chemical energy, thus chemical energy is the product. This is different from respiration because respiration transforms chemical energy into energy usable by cells; in this case chemical energy is the source. Photosynthesis occurs in the chloroplas
The Effects of Photosynthesis on Bean Plants
Purpose: To determine how the quantity of light will effect the growth of a bean from seed.
Hypothesis: I think that the bean that is in light constantly for 24 hours will grow more quickly than the bean in full sunlight and in partial sunlight.
How does the Amount of CO2 Affect the Rate of Photosynthesis?
There are a number of variables that can affect the photosynthesis rate of Canadian water weed (Elodea). They are as follows:
 The amount of light: an increased light level increases the rate of photosynthesis to a certain poi
To work out how light intensity can affect the rate of photosynthesis.
I think that the further away the light source is the smaller the rate of photosynthesis is. This is because there is a further distance for the light to each the plant in order for it to photosynthesise. Alth
I plan to investigate how light intensity affects the rate of photosynthesis in pondweed. The rate of photosynthesis will be measured by the number of bubbles given off (considering that oxygen is produced as a waste gas during photosynthesis). The light intensity is measured by the distance
The Entire Process of Photosynthesis
Photosynthesis is the process by which organisms that contain the pigment chlorophyll convert light energy into chemical energy which can be stored in the molecular bonds of organic molecules. Photosynthesis powers almost all trophic chains and food webs on th
Photosynthesis is a two stage process. The first process is the Light Dependent Process (Light Reactions), requires the direct energy of light to make energy carrier molecules that are used in the second process. The Light Independent Process (or Dark Reactions) occurs when the products of the Light
Cellular Respiration vs. Photosynthesis
To obtain energy needed for life, organisms depend on the processes of cellular respiration and photosynthesis. Though they share the same function of changing energy from one form to another, there are many differences between cellular respiration and pho
Photosynthesis is used to synthesize complex organic materials from carbon dioxide, water, and inorganic salts, using light as the source of energy. The purpose of this experiment was to measure the optimum wavelength and light intensity at which photosynthesis occurs. A buffer soluti
Cellular Respiration and Photosynthesis
Photosynthesis is the process by which plants, some bacteria, and some protistans use the energy from sunlight to produce sugar, which cellular respiration converts into ATP, the "fuel" used by all living things. The conversion of unusable sunlight energ
Light Absorption by Photosynthetic Pigments in Silver Beet
The aim of the experiment was to determine the absorption of differing wavelengths of light by individual pigments in the vegetable silver beet. Pigments were extracted from silver beet leaves and separated into chlorophyll a, c
Photosynthesis - An Overview
There are 3 basic types of photosynthesis: C3, C4, and CAM. Each has advantages and disadvantages for plants living in different habitats.
All 3 forms of photosynthesis are based on two pathways. The first are the light reactions, where energy from the sun is abs
Examination of How Different Colours of Light Affect
The Rate of Photosynthesis
Plants are an essential part of the food chain required by all living things to survive. The growing world population and subsequent alteration to the natural environment has placed increased pressu
The rate of photosynthesis is affected by a number of factors including light levels, temperature, availability of water, and availability of nutrients. If the conditions that the plant needs are improved the rate of photosynthesis should increase.
The maximum rate of photosynthesis will be const
Account of photosynthesis
Photosynthesis is a natural process which occurs in every single plant worldwide. The main site for photosynthesis is within the cellular organelles known as chloroplasts. These chloroplasts contain a specific membrane known as the thylakoid membrane where the light depe
Photosynthesis is a life providing process for both plants and animals. It provides food for plants, and oxygen for animals. Photosynthesis is almost the exact opposite of cellular respiration. The equation for cellular respiration is C6H12O6 + 6O2 ( 6H2O + 6CO2 + energy; whi
