respiration in plant
Answers
Answer:
Respiration is essential for growth and maintenance of all plant tissues, and plays an important role in the carbon balance of individual cells, whole-plants and ecosystems, as well as in the global carbon cycle.
Answer:
Respiration in plants
Just like animals plants also respire (take oxygen in and release carbon dioxide). They use oxygen for the breakdown of food and release carbon dioxide. It can be represented by an equation as
Glucose (food) + Oxygen ---------> Carbon dioxide + water + energy.
The intake of oxygen and release of carbon dioxide is through different routes in different parts of the plants.
In leaves and stem, exchange of gases takes place through stomata (guarded pores).
In stem with bark, exchange of gases take place through the lenticels.
Root cells take the air (through diffusion) in the soil spaces.
The oxygen in the air is then utilized for breaking down glucose to release energy and carbon dioxide.
Respiration in most plants occurs under dark conditions (no light).
