The process of respiration in plants continues day and night.
Entry of Oxygen: -
Oxygen from air spaces on leaves diffused into tissues and cells. Then this
oxygen dissolves in film of water present over cells. In cells this oxygen
oxidizes the carbohydrates to produce energy.
Excretion of CO2: -
Some carbon dioxide is used in photosynthesis. Remaining is passed out
through lenticels and stomata.
Water: -
Water produced in this process becomes a part of already present water.
Rate of Respiration: -
This process takes with faster rate in those parts, which have rapid growth like
growing seeds, buds etc because these parts require more energy to grow.
