How do plants breathe, inhaling oxygen or carbon dioxide?

The respiration of plants is to inhale oxygen and exhale carbon dioxide. Plant respiration is mainly carried out in the mitochondria of cells. The whole process of aerobic respiration can be divided into three stages: the first stage (called glycolysis), in which one molecule of glucose is decomposed into two molecules of pyruvate, producing a small amount of hydrogen (represented by [H]) during the decomposition process. At the same time, a small amount of energy is released. This stage is carried out in the cytoplasmic matrix.

The breathing process of plants involves inhaling oxygen and releasing carbon dioxide. This process is mainly carried out in the mitochondria of plant cells. Respiration can be divided into three stages: glycolysis, in which one molecule of glucose is broken down into two molecules of pyruvate, releasing a small amount of hydrogen (represented by [H]) and energy. This reaction occurs in the cytoplasmic matrix.

Plants do not necessarily exhale oxygen and inhale carbon dioxide. When plants engage in photosynthesis, they exhale oxygen and inhale carbon dioxide. But when plants breathe at night, they exhale carbon dioxide and inhale oxygen. The main functions of plants are photosynthesis and respiration.

Plant respiration

1. Plant respiration is a basic biological process in which they use oxygen to decompose sugars and release energy. This is contrary to photosynthesis, in which plants inhale carbon dioxide and release oxygen. Respiration occurs in every cell of a plant, and both day and night require energy to sustain its life.

2. Plant respiration can provide energy for its life activities, and the energy stored by respiration can be used in various life activities of organisms, such as cell division and plant growth. The respiration process of plants can provide raw materials for the synthesis of compounds in vivo, such as pyruvate, an intermediate product of glucose decomposition, is the raw material for the synthesis of amino acids.

3. Respiration is a key energy conversion process in plant metabolism, which is similar to human dietary activities. It refers to the process of gradual oxidation of plant cells under the action of enzymes, through oxidation to form simpler substances and release energy, which is plant respiration. There are two types of respiration: aerobic and anaerobic. Aerobic respiration evolved from anaerobic respiration.

4. Plant respiration refers to the process in which plants absorb oxygen from the air through stomata and release carbon dioxide. The respiration of plants is different from that of animals, including cell respiration, stomatal respiration and root respiration. It should be noted that plant respiration and photosynthesis are interrelated. In the case of sufficient light, plants absorb carbon dioxide through photosynthesis and release oxygen while breathing.

5. Plant respiration is a necessary process for plants to obtain life. this process is divided into aerobic respiration, anaerobic respiration, and then under aerobic conditions, glucose in plants decomposes glucose by reacting with oxygen and releases a lot of energy. supply plant life, in anoxia, plants break down glucose into lactic acid or alcohol, but release a small amount of energy, in short, Respiration is the process by which plants decompose glucose into energy in order to obtain biological energy.

6. In the case of sufficient oxygen, plants can release energy efficiently, which is very important for plant life activities, such as cell division, growth and development, and mineral absorption. However, when oxygen is insufficient, the respiratory efficiency decreases, and the lactic acid or alcohol produced has an adverse effect on plant growth, indicating that the role of respiration is diverse and dynamic under different conditions.

What is the respiration of biological plants in high school?

1. Respiration is a key energy conversion process in plant metabolism, which is similar to human dietary activities. It refers to the process of gradual oxidation of plant cells under the action of enzymes, through oxidation to form simpler substances and release energy, which is plant respiration. There are two types of respiration: aerobic and anaerobic. Aerobic respiration evolved from anaerobic respiration.

2. Respiration is the core energy transformation process in plant metabolism, which is similar to the human body eating to obtain energy. Through the action of enzymes, plant cells gradually oxidize complex substances and release energy, which is called respiration. Respiration is mainly divided into aerobic respiration and anaerobic respiration.

3. Respiration is the process in which plants consume organic matter, absorb oxygen and release carbon dioxide through mitochondria. This is like the "eating" process of plants, which consumes the organic matter produced by photosynthesis in order to maintain life activities.

4. When learning biology, senior high school students often come into contact with three basic biochemical processes: photosynthesis, respiration and transpiration. They play different roles in organisms and work together to maintain ecological balance. Photosynthesis is that plants use sunlight energy to combine water and carbon dioxide to produce oxygen and organic matter and store energy. This process is the main source of energy for all life on Earth and provides indispensable support for the maintenance of ecosystems.

5. Photosynthesis refers to the process in which green plants use light energy to convert carbon dioxide and water into organic compounds that store energy and release oxygen through chloroplasts. We inhale the oxygen released by photosynthesis all the time. The food we eat every day also comes directly or indirectly from organic matter produced by photosynthesis.

6. Photosynthesis is a biochemical process in which plants, algae use chlorophyll and some bacteria use their cells themselves to convert carbon dioxide and water (bacteria are hydrogen sulfide and water) into organic matter and release oxygen (hydrogen released by bacteria) under visible light. Plants are called food chain producers because they can use inorganic matter to produce organic matter and store energy through photosynthesis.
