The highest rate of respiration are found in the actively growing root and stem tips, cambium and embryos of germinating seeds and lowest rates in dormant seeds or spores. As, the growing tips are generally rich in meristematic tissues the rate of respiration is also high.
- Root and stem tips: These regions are actively growing and require energy for cell division, elongation, and differentiation.
- Buds: Buds are also actively growing and undergo rapid cell division and differentiation, requiring significant energy.
- Germinating seeds: During germination, seeds are metabolically active as they undergo processes like hydration, enzyme activation, and growth of the embryo, all of which require substantial energy through respiration.

In which part of the plant, respiration rate is higher :a)Root and ste...
Explanation:
Respiration is the process by which cells release energy from food molecules. It occurs in all living cells, including those in plants. In plants, respiration takes place in different parts of the plant.
Root and stem tip:
The root and stem tip are the growing parts of the plant. They require a lot of energy for cell division and growth. Hence, the respiration rate is higher in these parts.
Buds:
Buds are the developing parts of the plant where new leaves, stems, and flowers are formed. The respiration rate is higher in buds as they require energy for growth and development.
Germinating seeds:
Germinating seeds are the ones that have just started to grow. They require energy for cell division and growth. Hence, the respiration rate is higher in germinating seeds.
All of these:
From the above explanations, it is clear that the respiration rate is higher in root and stem tip, buds, and germinating seeds. Hence, the correct option is 'D'.

Respiration converts oxygen and the sugars generated during photosynthesis into carbon dioxide, water and energy. In addition to the type of plant, several environmental factors affect a plant cell's rate of respiration. Plants"breathe" as part of the growth cycle.
