Which cells does photosynthesis take place?
Photosynthesis takes place inside plant cells in small objects called chloroplasts . Chloroplasts contain a green substance called chlorophyll . This absorbs the light energy needed to make photosynthesis happen. Plants and algae can only carry out photosynthesis in the light.
Which cells do the most photosynthesis?
The palisade mesophyll consists of cells packed together and rich in chloroplasts. Eighty percent of photosynthesis occurs in the palisade mesophyll.
What four things are needed for photosynthesis?
What is photosynthesis?
- Photosynthesis is a chemical reaction that takes place inside a plant, producing food for the plant to survive.
- Carbon dioxide, water and light are all needed for photosynthesis to take place.
- Photosynthesis happens in the leaves of a plant.
What is the photosynthesis equation?
The process of photosynthesis is commonly written as: 6CO2 + 6H2O → C6H12O6 + 6O2. This means that the reactants, six carbon dioxide molecules and six water molecules, are converted by light energy captured by chlorophyll (implied by the arrow) into a sugar molecule and six oxygen molecules, the products.
Which part of the leaf is most active in photosynthesis?
palisade mesophyll
Most photosynthesis takes place in the palisade mesophyll, which is conveniently located at the top of the leaf just under the epidermis.What are the 3 types of photosynthesis?
The three main types of photosynthesis are C3, C4, and CAM (crassulacean acid metabolism).
What are the 7 steps of photosynthesis?
Terms in this set (7)
- Step 1-Light Dependent. CO2 and H2O enter the leaf.
- Step 2- Light Dependent. Light hits the pigment in the membrane of a thylakoid, splitting the H2O into O2.
- Step 3- Light Dependent. The electrons move down to enzymes.
- Step 4-Light Dependent.
- Step 5-Light independent.
- Step 6-Light independent.
- calvin cycle.
Which leaf has the most stomata?
Explanation: All surfaces of the leaf have some amount of stomata for regulating gas exchange for photosynthesis. However, the lower epidermis (the underside of the leaf) has more, because it is more often in the shade and so it is cooler, which means evaporation won’t take place as much.
What parts of the leaf are involved in photosynthesis?
chloroplasts
In plants, photosynthesis takes place in chloroplasts, which contain the chlorophyll. Chloroplasts are surrounded by a double membrane and contain a third inner membrane, called the thylakoid membrane, that forms long folds within the organelle.What is a photosynthesis example?
An example of photosynthesis is how plants convert sugar and energy from water, air and sunlight into energy to grow. The water from the leaves evaporates through the stomata, and filling its place, entering the stomata from the air, is carbon dioxide. Plants need carbon dioxide to make food.
What is the most efficient type of photosynthesis?
In sugar cane, which is one of the most efficient plants, about 8% of the light absorbed by the plant is preserved as chemical energy. Given that photosynthesis is the direct or indirect source of all human food, this kind of slacking is clearly just not good enough.
What is photosynthesis in short form?
photosynthesis. [ fō′tō-sĭn′thĭ-sĭs ] The process by which green plants, algae, diatoms, and certain forms of bacteria make carbohydrates from carbon dioxide and water in the presence of chlorophyll, using energy captured from sunlight by chlorophyll, and releasing excess oxygen as a byproduct.
What 3 things are needed for photosynthesis?
Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.
What are the 3 products of photosynthesis?
Photosynthesis involves three elements: carbon, hydrogen, and oxygen. You have seen that the products of photosynthesis are oxygen and glucose.
