From where do the roots of the plants take in oxygen?

Correct option is B

The correct answer is (b) From the air spaces in between the soil particles.

Information Booster:

• In addition to the leaves, the root system also contributes to plant respiration.
• The soil's tiny air pockets can provide the roots with oxygen to breathe. 
• Oxygen (O₂) from the soil pores diffuses into the root hairs of root systems, where it is carried to all regions of the roots.
• During respiration, plant roots utilize photosynthates for a variety of purposes, including nutrition in take,tissue maintenance, and growth.
• The created carbon dioxide (CO₂) is subsequently released into the soil, where it diffuses into the atmosphere through soil pores.
