The word photosynthesis can be separated to make two smaller words: Most plants are able to make their own food whenever they need it. This is done using light and the process is called photosynthesis. Photosynthesis is the process by which plants make their own food.
Back to Top 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 ATPthe "fuel" used by all living things.
The conversion of unusable sunlight energy into usable chemical energy, is associated with the actions of the green pigment chlorophyll. Most of the time, the photosynthetic process uses water and releases the oxygen that we absolutely must have to stay alive.
Oh yes, we need the food as well! We can write the overall reaction of this process as: Image from Purves et al.
Leaves and Leaf Structure Back to Top Plants are the only photosynthetic organisms to have leaves and not all plants have leaves. A leaf may be viewed as a solar collector crammed full of photosynthetic cells. The raw materials of photosynthesis, water and carbon dioxide, enter the cells of the leaf, and the products of photosynthesis, sugar and oxygen, leave the leaf.
Cross section of a leaf, showing the anatomical features important to the study of photosynthesis: Water enters the root and is transported up to the leaves through specialized plant cells known as xylem pronounces zigh-lem.
Land plants must guard against drying out desiccation and so have evolved specialized structures known as stomata to allow gas to enter and leave the leaf.
Likewise, oxygen produced during photosynthesis can only pass out of the leaf through the opened stomata. Unfortunately for the plant, while these gases are moving between the inside and outside of the leaf, a great deal water is also lost.
Cottonwood trees, for example, will lose gallons of water per hour during hot desert days. Carbon dioxide enters single-celled and aquatic autotrophs through no specialized structures. Pea Leaf Stoma, Vicea sp.

The order of colors is determined by the wavelength of light. Visible light is one small part of the electromagnetic spectrum.
The longer the wavelength of visible light, the more red the color.Study the general equation for photosynthesis and be able to indicate in which process each reactant is used and each product is produced. List the two major processes of photosynthesis and state what occurs in those sets of reactions.
• Cellular Respiration Equation (Products and Reactants) PHOTOSYNTHESIS vs. RESPIRATION Compare and Contrast: Draw the organelle responsible for each. Label the major parts, show where all processes are occurring and show where the H+ concentration occurs.
Write out a balanced equation for photosynthesis: Experimental Design Your table will design an experiment to test how a selected variable affects the rate of photosynthesis. Photosynthesis, ATP and Cell Respiration Chapter 8 study guide by Jdesplaces includes 34 questions covering vocabulary, terms and more.
The formula for photosynthesis is 6CO2 + 6H2O + light energy = C6H12O6 + 6O2. In words, the equation translates to the combining of water, carbon dioxide and light energy to produce glucose and oxygen. Photosynthesis is a complex natural process that .
