Cellular Respiration In Plants Experiment

In this experiment we will be using the same plant you examined in Lab 3 called Elodea.

Cellular respiration in plants experiment. C 6H 12O 6 6 O 2 6 H 2O 6 CO 2 energy All organisms including plants and animals oxidize glucose for energy. This respiration will consume the oxygen that has accumulated and possibly cause the plant disks to sink. Cellular respiration in plants respiration in which carbon dioxide is absent is called cellular respiration.

However plants are unique in that they can use the CO 2 they produce during cellular respiration as a reactant in photosynthesis. When plants use sugars stored in their leaves or seeds they undergo cellular respiration Sugar Oxygen Carbon dioxide Water Energy ATP In this experiment you will use a substance called calcium hydroxide that absorbs any carbon dioxide in the air and converts it to solid calcium carbonate. The most basic plant respiration experiment will simply demonstrate that plants do respire thus creating carbon dioxide.

Photosynthesis the process through which leaves make food on their own is called photosynthesis. In turn the oxygen is a vital component in aerobic cellular respiration. Respiration is a set of chemical processes that break down nutrient molecules in living cells to release energy in usable form.

The molecule H 2 O is water and finally ATP is cellular. The collection of biochemical reactions that plants undergo. Cells respire in this situation.

The AP Biology Lab 5 uses respirometry techniques to calculate the rate of oxygen consumption cellular respiration in germinating pea seeds. Trapped inside a closed jar as carbon dioxide is produced during cellular respiration it dissolves in water producing an acidic environment that can be measured using bromthymol blue. While this is going on the leaf is also carrying out cellular respiration.

It turns red when an acid is added to it and blue when a base is added to it. Measuring carbon dioxide production is an indirect way of measuring whether or not cellular respiration is occurring. Rubber stoppers Respiration bottle setups.
