why is elodea used?

Question

i wont be using a microscope in the experiment, so is there something else good about using elodea, like does it photosynthesise quick or something?

Answer 1

think it must do, thats why its cheap and abundant for fish tanks. sorry, i couldn't honestly say.

Answer 2

Elodea also known as Canadian pond weed, is a water plant which, is easy and cheap to obtain.

It also photosynthesises in a way that can be easily observed

Carbon Dioxide + Water > Glucose + Oxygen

the oxygen that is produced can be seen as bubbles coming off of the leaf, these bubbles can be collected with a test tube and tested with a glowing splint, which will prove the bubble are oxygen.

Also if you want to show how different light intensity (etc) can affect photosynthesis, you can change the light intensity and clearly see the what speed the bubble come off the Elodea at.

More light = more oxygen (bubbles) - until point where it will not get any faster.

Answer 3

I did that experiment! I warn you - its boring. Anyway, there are several reasons for you using Elodea, otherwise known as Canadian pond weed (don't know why). Firstly, it's cheap, and you can get it from any garden centre. Secondly photosynthesises very quickly, and the effects of light shining on it can be seen within a few seconds. Thirdly, as its a water plant, you can see bubbles rising from the leaves - oxygen from the photosynthetic process, so by counting the number of bubbles, and measuring the volume of oxygen produced, you can quantify the rate of photosynthesis easily. Hope that helps!

Answer 4

Elodea certainly does photosynthesise and produces oxygen which you can see bubbling up from the leaves - assuming you keep it under water as you would do in a fish tank. It is also easy to get from a pet shop/aquarium and is relatively cheap.

Answer 5

Usually, when a microscope is available, the cells of elodea leaves are known for their vivid exhibition of cyclosis, or cytoplasmic streaming. Chloroplasts make use of cytoplasmic streaming to move to optimum position within the cell for maximum light absorption used in photosynthesis. The rate of motion is usually affected by light exposure, temperature, and pH levels.

Otherwise: Elodea will grow in a wide range of conditions, from very shallow to deep water, and in many sediment types. It can even continue to grow unrooted, as floating fragments. It is found throughout temperate North America, where it is one of the most common aquatic plants. It is an attractive and easy to keep aquarium plant.

Answer 6

Elodea is a genus of aquatic plants often called the Water weeds. Elodea is native to North America and it is also widely used as aquarium vegetation. The introduction of some species of Elodea into waterways in parts of Europe, Australia, Africa, Asia, and New Zealand has created a significant problem, and it is now considered a noxious weed in these areas.

Elodea canadensis, sometimes called American or Canadian waterweed/pondweed or Anacharis (a former scientific name) is widely known as the generic water weed.

American waterweed is an important part of lake ecosystems. It provides good habitat for many aquatic invertebrates and cover for young fish and amphibians. Waterfowl, especially ducks, as well as beaver and muskrat eat this plant. Also, it is of economic importance as an attractive and easy to keep aquarium plant. It was used as a drug by the Iroquois.

Answer 7

It's known for making oxygen in sunlight, is that something eles?
