Answer 1

1)

In plants the products of respiration is molecular oxygen. In animals the product is CO2.

2)

CO2 , water and light are reactants of photosynthesis.

3)

• During light , increased respiration and so animals produce more energy and release CO2.
• In dark animals respire , increase in co2.
• In light , plants respire , increase in O2.
• In dark , plant respire , increase in CO2.
• In light , decrease in germination of seeds, there fore decrease in co2. (seeds release CO2 while respiration )
• In dark , incraese in CO2.

4)

• Positive values indicate that the plant is photosynthesing and negative values shows that plant is undergoing respiration.

5)

• Measuring CO2 levels in dark plants and animals shows respiration .
• So, animal -light and dark ; plant in dark , seeds in dark show respiration.

6)

• Plants in light shows photosynthesis.

7)

• Yes , it occurs . lIght plant and cellular respiration here denotes it as aerobic respiration. In dark anerobic respiration takes place.

8)

• Just measuring CO2 rates doesnot show the exact cellular metabolism.
• Respiration rates denotes the exact cellular metabolism . Hence it is useful to calculate respiration rates.
