Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
____ reaches the air in the soil particles .
A
root
B
root hair
C
root particles
D
None of the above
Explanation: 

Detailed explanation-1: -Final Answer: Root hair carry out exchange of oxygen and carbon dioxide to and from tiny air pockets present in between soil particles.

Detailed explanation-2: -In root systems, oxygen (O2) in soil pores diffuses into the root hairs and gets transported to all parts of the roots. Plant roots use photosynthates during respiration for their various functions, like nutrient uptake and maintaining and growing their tissues.

Detailed explanation-3: -Root hair cells Plants absorb water from the soil by osmosis. They absorb mineral ions by active transport, against the concentration gradient. Root hair cells are adapted for taking up water and mineral ions by having a large surface area to increase the rate of absorption.

Detailed explanation-4: -They grow vertically upwards in air, above the soil level and respire so called respiratory roots or pneumatophores.

Detailed explanation-5: -Pneumatophores. These specialized aerial roots enable plants to breathe air in habitats that have waterlogged soil. The roots may grow down from the stem, or up from typical roots.
