Question

In anaerobic respiration seeds respire___________.

  1. In presence of O2
  2. In presence of CO2
  3. In absence of O2
  4. In absence of CO2

hintHint:

Respiration is of two types- aerobic and anaerobic. One of these options is part of a plant that will be insulated from the atmosphere or soil air reserve that part would be capable of anaerobic respiration.

The correct answer is: In absence of O2


    In anaerobic respiration, seeds respire In absence of O2

    • When oxygen is present, respiration can be aerobic, or it can be anaerobic, when there is no oxygen present.
    • Aerobic respiration releases considerably more energy and results in the complete oxidation of reduced substrates.
    • Since anaerobic respiration is an incomplete oxidation process, during germination seed respire in the absence of oxygen.
