Plants convert energy from sunlight into sugar in a process called photosynthesis. Photosynthesis uses energy from light to convert water and carbon dioxide molecules into glucose sugar molecule and oxygen Figure 2. Simple equation describing the molecules required for photosynthesis and its products. There are several structures within a leaf that have important roles in the movement of nutrients and water throughout a plant.
Photosynthesis is a chemical reaction in which light energy is converted to chemical energy in glucose. It is the means by which the energy in sunlight becomes usable to living things.
Living things can eat glucose, we can't eat sunlight. Exactly why is photosynthesis so important? One product of photosynthesis is glucose sugarwhich provides the basis for most food chains.
The second product of photosynthesis is oxygen which comes in handy if your happen to be an aerobic organism that requires oxygen for survival. Where does photosythesis occur? This question can be answered on various levels. In terms of organisms, photosynthesis occurs in autotrophes that contain the green pigment chlorophyll.
On the multicellular level, photosynthesis occurs in the leaves of plants. On the cellular level, the reactions for photosynthesis occur in organelles called chloroplasts in eukaryotic cells.
Blue-green algae which are prokaryotic carry-out the photosythesis reactions in the cytoplasm. What raw materials are needed for the process of photosynthesis?
As mentioned in the above box, chlorophyll must be present. Chlorophyll absorbs solar energy.
To which "life function" is photosynthesis related? Photosynthesis falls under nutrition, autotrophic nutrition to be exact. Nutrition has to do with how organisms obtain the materials necessary for energy, growth, etc. We call these necessary materials nutients. How can we summarize photosynthesis?
In words, remember this: What else should we remember about photosynthesis? Well, it's an important component of the Oxygen-Carbon Dioxide Cycle. Organisms that carry-out photosynthesis are like oxygen factories. At the same time they are removing CO2 from the atmosphere.
Increasing levels of CO2 appear to go hand in hand with increasing global temperature "Global Warming". So damaging the ecosystems where photosynthesis occurs i. For the most part, when thinking of organisms that carry-out photosynthesis, it is safe to picture plants.
So let's not forget them completely. The leaves of plants are the photosynthesis factories. The structure of a "typical" leaf is illustrated in the following table. Please note that each roundish shape is a single plant cell.
So each layer is a plant tissue a group of cells. The area sandwiched in the middle of the leaf is referred to as "mesophyll". There are two layers in the mesophyll: These lines are veins, or "vascular bundles" the side of one bundle is colored light green.Three of the Four Stages in Photosynthesis Occur Only during Illumination.
It is convenient to divide the photosynthetic process in plants into four stages, each occurring in a defined area of the chloroplast: (1) absorption of light, (2). Several elements may affect the rate of photosynthesis: carbon dioxide concentration, temperature and light intensity.
If there is insufficient carbon dioxide, a plant cannot photosynthesize, even if it has plenty of light.
If it is too cold, the rate of photosynthesis will drop. . RECOMMENDED READING FOR SERIOUS AQUARIUM KEEPERS LOOKING TO MOVE PAST THE BASICS.

Photosynthesis will occur in plants, algaes, and different species of bacteria, and organisms that can perform photosynthesis are referred to as photoautotrophs, meaning they can create their own food.
Photosynthesis, a plant's internal process that converts light energy into food, takes place mostly in the leaves of plants. Plants and trees utilize specialized structures to conduct the chemical reactions necessary to transform sunlight into chemicals the plant can use. In photosynthesis, the energy from the sun is used to turn carbon dioxide (CO 2) and water into sugar.
Oxygen is a waste product. Oxygen is a waste product. More light can mean more photosynthesis.
Jun 14, · Best Answer: photosynthesis occurs during the daytime, it's when light energy is converted into chemical energy (ATP) to be used to split water molecules to get hydrogen, the oxygen is released through the stomata, ATP is made in the rutadeltambor.com: Resolved. Photosynthesis mainly occurs during daytime as there would be light. The plant takes in the energy from the light and carbon dioxide to produce its 'food' and as a result oxygen is given out as a. Several elements may affect the rate of photosynthesis: carbon dioxide concentration, temperature and light intensity. If there is insufficient carbon dioxide, a plant cannot photosynthesize, even if it has plenty of light. If it is too cold, the rate of photosynthesis will drop. .
