Cellular Respiration In Plants Experiment

The experimental set-up involves a qualitative measurement of the CO 2 concentration in the vials.

Cellular respiration in plants experiment. Students use a carbon dioxide sensor to measure the rates of photosynthesis and respiration in spinach leaves. In this experiment the rate of cellular respiration in the germinating peas in both water. Due Next Class Term 1 Exam.

First you will examine photosynthesis and then cellular respiration. Respiration is a set of chemical processes that break down nutrient molecules in living cells to release energy in usable form. Cellular Respiration Lab Overview In this experiment you will work with seeds that are living but dormant.

Then students conduct an experiment to evaluate changes in CO 2 concentration in the air around plants in the light vs. 18 Cellular Respiration AP Lab Report. This respiration will consume the oxygen that has accumulated and possibly cause the plant disks to sink.

In turn the oxygen is a vital component in aerobic cellular respiration. 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. For example students may investigate photosynthesis and cellular respiration in aquatic plants but may want to do another investigation to learn about photosynthesis and cellular respiration in seeds before and during germination.

The most basic plant respiration experiment will simply demonstrate that plants do respire thus creating carbon dioxide. This module is designed so that students can be assessed. However plants are unique in that they can use the CO 2 they produce during cellular respiration as a reactant in photosynthesis.

In this experiment we will be using the same plant you examined in Lab 3 called Elodea. 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. When the necessary conditions are met germination occurs and the rate of cellular respiration.
