Respiration in plants important points For NEET

Respiration in plants important points:Respiration in the plants is a process that releases the energy stored in organic compounds by breaking down the glucose and other organic molecules into carbon dioxide and water as byproducts. It occurs in all parts of plant and can be divided into two different stages: glycolysis and Krebs cycle.

Environmental factors such as the temperature, light, and carbon dioxide levels influences rate of the respiration, which can be higher during day and slower at night. Respiration in the roots, leaves, stems, fruits, and seeds is important for supporting the growth, maintaining acid-base balance, and ripening. Respiration can also plays a role in the plant defense, disease and disorder, and genetic modification.

Overall, respiration is crucial for life of plants, providing energy for the growth, reproduction, and survival.

NCERT Biology Class 11 Chapter 14, 25 important points – Respiration in plants important points

There are 25 important points on Respiration in plants important points

1. Respiration in plants is a process by which they releases the energy stored in the organic compounds.

2. This process occurs in all parts of  plant, including the leaves, stems, roots, and fruits.

3. During the process of respiration, glucose and the other organic molecules are broken down into carbon dioxide and water, releasing the energy in the form of ATP.

4. Respiration in the plants can be divided into two different stages: glycolysis and  Krebs cycle.

5. During the glycolysis, glucose is broken down into the pyruvate, which is then further processed in  Krebs cycle.

6. The Krebs cycle takes place in mitochondria and is where  majority of the energy releases occurs.

7. The rate of the respiration in plants is influenced by the environmental factors such as the temperature, light, and carbon dioxide levels.

8. Higher the temperatures and increased light levels tends to increase rate of respiration in plants.

9. The availability of the oxygen also affects the rate of respiration, with anaerobic respiration occurring in absence of oxygen.

10. During day time, plants often respires at a higher rate than they photosynthesize, using the stored energy to provide support and  growth and other processes.

11. At night time, respiration can continue but at a quite slower rate, with the plant relying on the stored energy to support the basic metabolic processes.

12. Respiration in the plants also produces heat, which can be used to regulate the plant temperature in the extreme environments.

13. Respiration also plays a role in carbon cycle, with plants absorbing the carbon dioxide through photosynthesis and releasing it through the process of respiration.

14. Respiration in the roots is important for supporting overall health of  plant, with roots respiring at a higher rate to support growth and the nutrient uptake.

15. In addition to providing the energy, respiration also helps to maintain the acid-base balance within plant by producing the bicarbonates.

16. Different plant species can have different respiratory rates, with some species respiring more efficiently than the other one.

17. Respiration in the plant leaves is often most important source of energy release, with leaves containing large amounts of the chloroplasts and mitochondria.

18. Respiration also plays a role in the seed germination, with the stored energy being used to support growth of the young plant.

19. Respiration in the fruits is important for ripening process, with release of energy allowing the fruits to soften and mature.

20. Respiration can also play a role in the plant defense mechanism, with some plant species releasing the toxic compounds through the process of respiration to deter herbivores.

21. Respiration in the plant stems is important for supporting the growth and transportation of water and nutrients throughout the plant.

22. Some plant species are able to adjust their respiratory rates in response to the changes in the environmental conditions, such as drought.

23. Respiration can also be affected by the various diseases and disorders, with some diseases reducing efficiency of respiration and leading to the decreased growth and vigor.

24. In some of the cases, genetic modification can be used to improve efficiency of the respiration in plants, leading to improved growth and productivity.

25. Overall, respiration plays a crucial role in  life of plants, providing energy for the growth, reproduction, and survival in a changing environment.
