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 we find that Cabomba is a much more reliable plant for this purpose.

What is the purpose of elodea?

Elodea provides shelter and food for many aquatic insects, crustaceans and fish. Elodea is often used in decorative purposes in the freshwater aquariums. Elodea quickly grows in waters rich in nitrogen and phosphorus. Rapid growth of elodea reduces oxygen content in the water and leads to fish kills.

Why is pondweed used for photosynthesis experiments?

Like other green plants, pond weed can make sugar from carbon dioxide and water. ... Red light is more easily used by the pond weed than most other colours. This process of making sugar and oxygen is called photosynthesis. Pond weed uses the carbon dioxide which is dissolved in the water it is in.

Does elodea do photosynthesis?

Through investigation, students observe that an Elodea plant in water and exposed to light performs photosynthesis. ... Students connect the role of chloroplasts to the process of photosynthesis. From these observations, students conclude that photosynthesis takes place in Elodea.

Why is an aquatic plant used in the experiment?

Why only hydrilla plant is used in the experiment to prove that oxygen is necessary for the photosynthesis. Because hydrilla is a small plant and hence easy to handle and also it is a aquatic plant so it is able to breath in water whereas land plants are not.

Does elodea produce oxygen?

Brazilian elodea (Egeria densa; formerly Elodea densa) and Canadian waterweed are commonly used in schools as an experimental plant for demonstrating cellular structures, such as chloroplasts and nuclei, and oxygen production during photosynthesis.

What does elodea release?

Snails will produce only carbon dioxide, while the Elodea will produce carbon dioxide and oxygen gas.

Why did the students use a water bath?

Why did the students use a water bath? To keep the temperature constant.

What is the relationship between oxygen and photosynthesis?

Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.

Why do we use sodium bicarbonate in photosynthesis experiment?

The function of the sodium bicarbonate in this experiment, was providing carbon dioxide for photosynthesis to occur. ... Once photosynthesis occurs for this type of reaction, sugar is produced. The energy used for a light independent reaction is energy (ATP) from the light dependent reactions and the sugar energy.

Is elodea a plant or animal?

Lack a cell wall, and have no central vacuole. This Elodea leaf cell exemplifies a typical plant cell. It has a nucleus, and a stiff cell wall which gives the cell its box-like shape. The numerous green chloroplasts allow the cell to make its own food (by photosynthesis).

Can photosynthesis occur in the dark?

The dark stage of photosynthesis is an intricate process where NADPH and ATP are used to produce carbohydrate molecules (or sugars). Unlike the light phase, it can happen in light or darkness. ... This light phase is necessary for the following phase, the dark phase, which doesn't necessarily need the presence of light.

What did the elodea plant take in during photosynthesis?

During photosynthesis, the plant absorbs carbon dioxide from the water and releases oxygen.

Which plant is used in Hydrilla experiment?

PROCEDURE:1)Place hydrilla plant twigs in a short stemmed funnel and keep it in a beaker containing water. 3)Place the apparatus in the sun for at least 2-3 hours. OBSERVATION:1)Gas bubbles i,e.,oxygen is produced at the end of test tube and remove the test tube gently.

Does Hydrilla produce oxygen?

Hydrilla, like all plants, gives off CO2 and uses oxygen during the night time (although the opposite is true during the day), which can bring oxygen levels to dangerously low levels for fish.

What plant is used in an experiment?

Plants for Rooting Experiments

Bulbs and corms that are easy to obtain and use include: amaryllis. lily. iris.

What does elodea need to survive?

Food: There is no need to feed; Elodea derives most of its nourishment from the water through its leaves and through light. Water: You should keep your Elodea fully submerged in water, so water in its habitat should be replenished as it evaporates with de-chlorinated water.

Does elodea grow fast?

Elodea grows very quickly and can reach a mature state within a week.

What is the relationship between snails and elodea?

The relationship between snails and elodea is symbiotic in that the snail eats algae and produces carbon dioxide. The elodea takes in the carbon dioxide and, through photosynthesis, creates oxygen, which the snail and every living thing in the tank uses to breathe.

What is the meaning of elodea?

: any of a small American genus (Elodea) of submerged aquatic monocotyledonous herbs.

What was your experimental design what is the relationship between snails and elodea?

What is the relationship between snails and Elodea? The snails produce the carbon dioxide. The Elodea then takes in the carbon dioxide, and produces the oxygen for the snail to take in. ... If the color changed, it meant that there was carbon dioxide in the test tube.

Why was elodea placed in both flasks?

the elodea in the flask left in the light was able to carry out photosynthesis / release oxygen.
