2. about pulmonary artery.The pulmonary artery is a big artery that comes from the heart. It splits into two main branches, and brings blood from the heart to the lungs. At the lungs, the blood picks up oxygen and drops off carbon dioxide. The blood then returns to the heart through the pulmonary veins.
3. There exist a concentration difference of carbon dioxide and oxygen inside the alveoli and capillaries due to which the diffusion of the two gases takes place. The carbon dioxide moves from the blood to the alveoli sac and the oxygen moves from the sacs to the blood.
Answer: Photosynthesis provides the materials that fuel cellular respiration.
Explanation:
Photosynthesis, the process through which green plants convert light to chemical energy. The energy that is gotten from sunlight by green plants, some protistans, and bacteria is used to produce sugar which is then converted to ATP by cellular respiration which is regarded to as the fuel that living things use.
Therefore, the statement that best explains why cellular respiration in plants and other organisms is dependent on photosynthesis is that photosynthesis provides the materials that fuel cellular respiration.
