Essays - largest database of quality sample essays and research papers on photosynthesis pondweed elodea sp. Measuring the rate of photosynthesis in elodea - lab 5 using the millimetre ruler as a guide, drag the slider to move the light source a distance of 200 mm from the sample of pondweed (elodea. Gives practice for long 6 mark questions in the new specification in starter activity includes activity using elodea pondweed and student worksheet. Assemble the equipment needed to measure the rate of photosynthesis in elodea (water plant) 3 count bubbles of oxygen gas given off by elodea to determine the rate of photosynthesis 4 change the conditions of photosynthesis by altering light intensity and.
Intensity and of light quality (ie, its colour) on the rate of photosynthesis on elodea canadensis the rate of photosynthesis is defined by the rate of oxygen production per unit mass (or area) of discovering photosynthesis by experiments. The directed study lesson is found in the student section of wow under the title studying the effect of ph diagram the relationship of photosynthesis and respiration with the approximately 12 x 3 sprigs of the common pondweed, elodea sp per. Water weed simulation this procedure can be accomplished by placing elodea plants in water with baking soda to provide carbon 100 results in the fastest rate of photosynthesis the more bubbles we see, the more photosynthesis is happening. In our lab we observed numerous plants and tissues types, however i will be focusing on our experiments with elodea cells as well as plastids explain how we would be studying and experimenting with pondweed for the the main site of photosynthesis and appear green because of. Pond weed investigation essaysthe effect of temperature on the rate of photosynthesis in canadian pondweed elodea sp in this investigation i plan to investigate how temperature effects the rate of photosynthesis in canadian pond weed, this will be achieved by comparing the amount of oxygen produce.
In this inquiry lab, students design and conduct simple experiments using elodea and bromothymol blue to determine whether plants consume or release carbon dioxide in the process of photosynthesis students will record their data which will be used to conclude whether carbon dioxide was consumed. Elodea canadensis taxon family canadian waterweed canada waterweed canadian pondweed canadian water pest american waterweed broad waterweed common waterweed water-thyme oxygen weed synonyms ( fusarium sp) was identified which damaged elodea in laboratory tests. Simple experiment to demonstrate oxygen production in pond weed as light intensity reduces so bubble count reduces. We will use canadian pondweed by counting these bubbles we can tell how fast oxygen is being given off from the photosynthesis we will place the elodea in a beaker along with warm water and a bit of sodium hydrogen carbonate (nahco3) if it wasn't. An aquarium tank containing sprigs of pondweed (elodea sp) with a digital oxygen sensor and portable data collecting device oxygen bubbles on the side of the tank are the result of photosynthesis.
Photosynthesis in aquatic plants pond weed (elodea sp) in a beaker of water, being used to demonstrate photosynthesis in aquatic plants one of the products of photosynthesis is the gas oxygen aquatic plants such as elodea give off visible bubbles of oxygen as photosynthesis takes place.
Leafy elodea was traded as an aquarium and pond plant unfortunately, it has escaped and causes problems including restricting water flow, increasing siltation herbicide group: l, inhibitors of photosynthesis at photosystem i (psi inhibitors. Elodea planchonii caspary: phca23: philotria canadensis (michx) britton: phli10: philotria linearis rydb classification click on a scientific name below to expand it in the plants classification report rank scientific name and common name. Photosynthesis practical - bubbling pondweed 43 3 customer reviews prepared this is a much more reliable version of the practical than the frequently used elodea pondweed free 43 3. Elodea water weed simulation objective: to observe how different variables affect the rate of photosynthesis in a water plant go to the following site.
Science fair project that examines how light wavelengths affect photosynthesis in the aquatic plant: elodea. Photosynthesis in pondweed (cabomba) i have been using elodea (canadian pondweed) for years which is so unreliable someone suggested i try cabomba (available from aquatic shops) and it is brilliant. Demonstrating oxygen formation during photosynthesis can be a tricky process one common way is to gather bubbles of gas given off by an aquatic plant this teaching resource introduces cabomba, a pondweed which is much more effective than the traditional elodea. Limiting factors in photosynthesis measuring the rate of photosynthesis this is a standard lab for ib usually canadian pondweed (elodea sp) is used and the bubble of oxygen counted as they are given off, or collected. Canadian pondweed (elodea canadensis) species distribution canadian pondweed all elodea species take up metals from the sediment and release them into the water (fusarium sp) has been identified that damaged elodea in laboratory tests.
