Photosynthesis is the process by which organisms use solar energy to make sugar and oxygen (nutrient molecules) from carbon dioxide and water (PimaCommunityCollege).
The chemical equation of this process is:
carbon dioxide + water =light energy=> glucose + oxygen
6CO2 + 6H2O =light energy=> C6H12O6 + 6O2, or
Six molecules of carbon dioxide plus six molecules of water produce one molecule of sugar plus six molecules of oxygen.
The two stages of photosynthesis:
The rate of photosynthesis varies with changes that occur in environmental temperature. In order to see how exactly different temperatures affect the rate, we can experiment with cotyledon plants. First, gather all the materials: 5 same size cotyledon plants, 5 clear closed containers to place the plants inside, and oxygen sensor to measure the rate of photosynthesis. Make sure to have 5 rooms with different temperatures but same amount of light and water for all plants. Control the temperatures…
The chemical equation for the process of photosynthesis is given as:
The photosynthesis equation is a simple representation for a very complex natural process.
The leaves are the organs for photosynthesis. It is where photosynthesis takes place. The structures of leaves are adapted for efficient photosynthesis:
Large surface area
Most leaves are broad and so have a large surface area allowing them to absorb more light.
A thin shape
A thin shape means a short distance…
Photosynthesis and Respiration
Through many years of school and history we have thought of Photosynthesis as
two opposite things, but they actually can’t work without each other. So in this essay we
will be comparing and contrasting photosynthesis and respiration.
Photosynthesis is a process used by plants and other organisms to convert light
energy, normally from the Sun, into chemical energy that can be later released to fuel
the organisms' activities.
During photosynthesis there is a twostage process…

Assessment Questions (Parts 1 and 2)
1. The Carotene pigment (light yellow) migrated the farthest on the chromatogram. The migration of the pigments occurred through rubbing a line of spinach with the side of a coin onto chromatography paper, then soaking the paper with 1 mL of chromatography solvent in a vial to allow absorption. The order of lines (absorption) was…
Photosynthesis and Cellular Respiration Review and Jeopardy
Light Dependent Reactions (Stage 1)
PS II (wavelength p680)
-Photons strike the chlorophyll in Photosystem 2 (PS II) and an electron absorbs the energy and becomes excited (photoexcitation), but has nothing to do with this energy.
-The electron travels from PS II (1st protein complex of 4) along the Electron Transport Chain (via mobile electron carriers) to harness the energy; across a series of reactions the electrons lose…
Plant Pigments and Photosynthesis
Statement of the Problem:
What question(s) are you trying to answer?
Include any preliminary observations or background information about the subject
If we use paper chromatography to separate the pigments in spinach leaves, then we will see several different pigments because plants use other pigments besides chlorophyll a (the green pigment) to capture visible light for photosynthesis.
1. What factors are involved in the separation of the pigments?
a. Some factors…
Plants use a number of absorption techniques to get the nutrients and moisture necessary for sturdy growth. As roots dive deep into the soil, they encounter air, water and nutrient reserves. In contrast, photosynthesising leaves discover sunlight and air as they rise up to the sky.
Roots act like sponges to absorb soil moisture.
carbon dioxide + water ————> sugar + oxygen
Balanced symbol equation:
structures in chloroplasts containing chlorophyll
ATP: adenosine tri-phosphate
-energy molecule of the cell
NADPH: electron carrier in cells
-Glucose: simple sugar made by plants in Calvin cycle (C6H12O6)
Stages of Photosynthesis
1: Pigments capture energy from sun
2: Light energy is converted to chemical energy (ATP and NADPH)
-Energy stored in chemical bonds
3: ATP, NADPH and CO2 used to make glucose

Photosynthesis & Cellular Respiration Research Paper
All living things on earth are made up of small structures called cells. Photosynthesis and cellular respiration are two of the most important energy producing processes that occur in these miniature structures, to maintain.
Photosynthesis is a chemical process that takes place in the presence of sunlight, in which plants make their food and build stores of energy. This event occurs in chlorophyll containing plant cells. Chlorophyll is a pigment…
