What does elodea need to stay alive?

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.

What environment does Elodea live in?

Grows in a variety of pond habitats but prefers to grow in fine sediments at the bottom of cool, spring-fed ponds. One of the few pond plants that can remain green all winter long. Reproduces primarily through stem fragments.

What affects the growth of Elodea?

Elodea plants grow almost entirely in water. The temperature of the water in which it is submerged significantly affects its growth rate, but that does not mean that it is not a sturdy plant. ... Even in icy temperatures during the winter, elodea continues to thrive, though its growth rate significantly drops.

Does Elodea need carbon dioxide?

How can I use Elodea to study 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.

Are Elodea cells alive?

The Elodea plant and the individual paramecium cell are both organisms because they can live on their own. ... Elodea cells are part of a bigger organism; paramecium are not. An organism is always free-living. It is not a part of a larger living organism.

How do you care for Elodea densa?

Anacharis can survive in water temperatures from 15 to 30° C (59 to 86° F), and prefers a neutral pH range of 6.5 to 7.5. Anacharis is a forgiving plant and tolerates a wide range of conditions but does best with moderate sunlight.

Do you think that Elodea lives in fresh water or in the sea?

Elodea normally lives in fresh water. What changes would you observe in the cells of an Elodea plant that was suddenly moved from fresh water to salt water?

Does Elodea need sunlight oxygen or carbon dioxide?

The plant uses sunlight to convert carbon dioxide and water into glucose, which is a carbohydrate. This all happens in the chloroplasts in the leaf cells using chlorophyll.

Can Elodea live in saltwater?

The Elodea plant which normally lives in low salt now finds itself in high salt. Water will move OUT of the plant, moving from low salt to high salt. This is plasmolysis. The cell membrane pulls away from the cell way.

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.

Can Elodea live in warm water?

Elodea is a popular, perennial water plant that grows easily in lakes, ponds, rivers, streams and aquariums worldwide. It is ideal for scientific studies in biology and research about water habitats and ecosystems. It grows stalks of leaves that bloom in warm temperatures.

What are the best growing conditions for Elodea?

Keep the habitat at temperatures ranging from 50 to 77° F for Egeria densa, and 45-65°F for Elodea canadensis. Your container should be large enough to submerge the entirety of the Elodea in treated water. Elodea can grow if it is free floating, but it does grow more vigorously if it is rooted in a substrate.

Is light required for Elodea to take up CO2?

blue (no CO2) is not only dependent on the presence of Elodea, but specifically on the Elodea being supplied with light.

Is Elodea good at photosynthesis?

The experiment proved that if the light source was too far away, photosynthesis would be slower and less productive. The procedure was to place Elodea under heat lamps and count the bubbles of photosynthesis in test tubes. A higher count of bubbles showed a higher rate of photosynthesis.

Why is Elodea important for lake ecosystems?

Ecological Importance. Elodea provides habitat for many small aquatic animals, which fish and wildlife eat. Geese, ducks, and swans are particularly attracted to this plant. Elodea is an excellent oxygen producer and frequently used by fish to protect fry.
