Breathing and respiration are the same process.
In breathing, only exchange of gases occurs.
Animals and plants both respire.
Plants give out carbon dioxide during respiration.
Germinating seeds release carbon dioxide which can turn limewater milky.
Oxygen enters plants only through roots.
Unicellular animals respire through their cell membrane.
Human lungs have millions of tiny air sacs called alveoli.
Blood absorbs carbon dioxide from alveoli during respiration.
Percentage: 0%
