Question

CO2 production by beans during Aerobic Respiration

Table:   CO2 Production by Beans
Beans	Indicator Color (Phenol Red)	Conclusion (CO2 present or absent)
Germinating	Yellow	Present
Ungerminated-dry	Red	Absent

Hypothesis: Growing beans will be respiring

Question: Does the data given support the hypothesis? Use the data to support your answer

Answer 1

The data supports the hypothesis because in case of germinating seeds the phenol red indicator showed

a)yellow color indicating the presence of carbondioxide.

b)If carbondioxide has to be produced this when the carbohydrates are used up and the by product is acidic in nature resuting in yellow color.

A reaction where carbohydrates are used up and resulting in the release of carbondixide is the cellular respiration.

The starch which is stored in the seeds are used as the source of carbohydrate.

Therefore this supports the hypothesis.
