Respiration+&+Photosynthesis

Respiration & Photosynthesis Animals Respiration Definition of Respiration: The process by which food molecules are broken down to release energy is called respiration. It occurs in all cells. Aerobic Respiration Definition of Aerobic Respiration: The process whereby food substances are broken down in the presence of oxygen, and energy is released in living cells is called aerobic respiration. Tissue respiration Definition of Tissue Respiration: Tissue respiration is the process by which food substances are broken down in living cells. External Respiration Definition of External Respiration: External respiration is the process of bringing the oxygen from the surrounding environment to the cells for tissue respiration to take place. Breathing What is breathing? Breathing refers to the movements that bring about an exchange of gases between the body and its surroundings. It is also the movement that brings air into and out of the body. Difference between inhaled and exhaled air: Difference between actions made when inhaling and exhaling: Plants Plants do not breathe in the same way as animals. Instead, the exchange of gases in flowering plants takes place mainly through openings in the leaves called stomata. During the day, oxygen leaves the leaf and carbon dioxide enters the leaf. However, during the night, oxygen enters the leaf and carbon dioxide leaves the leaf. Similarities and Differences

Reflection
After this lesson, I learn a lot. During primary school, I only learnt normal respiration for humans and also about photosynthesis. However, during this lesson, I learn more different kinds of respiration. I actually thought that there are only two ways to breathe, either respiration or photosynthesis, but through this lesson, I learned that there are more kinds of repiration, more detailed ones. I have also learnt about the differences between respiration and photosynthesis other than the difference in the time it happens and also what does those kinds of breathing.
