What is the photosynthesis method?
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.
Why is Elodea used in photosynthesis experiment?
This North American pondweed is widely recommended for demonstrating oxygen formation during photosynthesis. Elodea is cheap and easy to grow, but other pondweeds can also be used.
Does Elodea carry out photosynthesis?
Do Elodea plants carry out photosynthesis and cellular respiration at the same rate? Yes, plants can do photosynthesis and cellular respiration at the same time. When sunlight is available for the plant, the plant can use that energy to perform photosynthesis.
Why would we use Elodea SP for this experiment instead of terrestrial plant?
A water plant such as elodea (the type you commonly see in aquariums) does the process of photosynthesis just as plants that grow in the air do, but you can actually see the bubbles that indicate photosynthesis is occurring–they form on the leaves before they float to the surface, enabling an easy measurement of …
What was the dependent variable in the Elodea experiment?
The independent variable was the distance the light source was from the Elodea. In this lab the distances were 10 cm, 20 cm, and 30 cm away. The dependent variable was the rate of photosynthesis, which was determined by how many bubbles appeared when the light source was on.
How do you teach photosynthesis?
Using construction paper and crayons or markers, have your child design a pictorial representation of photosynthesis.
- Instruct your child to draw a plant or flower on the paper.
- Have your child draw a sun above the plant to symbolize the sun’s energy.
- Ask your child to add a source of water for the plant.
How do Elodea plants photosynthesis?
During photosynthesis, the plant absorbs carbon dioxide from the water and releases oxygen. Since oxygen is much less soluble in water than is carbon dioxide, the water quickly saturates with oxygen and bubbles form. The number of bubbles released per minute measures the rate of photosynthesis.
Why are Elodea leaves used in this lab?
carbon dioxide is a reactant that is used up during photosynthesis. In the first experiment, we will be using the same plant you examined in Lab 3 called Elodea. The experimental set-up involves a qualitative measurement of the CO 2 concentration in the vials. The variables to be examined in relation to carbon dioxide use
Is Elodea a plant or an animal?
The Elodea plant is indigenous to South America, and it has been recorded in Uruguay and Brazil. The aquarium trade has made it an invasive species in many regions of the world, and it has become established in North America, New Zealand, Northern Europe, Australia, and Japan.
Is Elodea an autotroph or a heterotroph?
Give an example of each. An autotroph is able to self-nourish, while a heterotroph must feed directly or indirectly on autotrophs to fulfill nourishment. Autotroph: Elodea Heterotroph: Deer 2. All the organisms of the same species in a given location make up a: Population 3.
Are Elodea plants harmful in an ecosystem?
One of the few aquatic plants that provides underwater habitat during the winter months. Modest amounts of elodea are generally considered beneficial for the pond ecosystem. Dense growth of elodea can interfere with some uses of the pond, such as boating and fishing.
