Euglena is a single-celled organism that performs both photosynthesis and respiration. During respiration, Euglena takes in oxygen and releases carbon dioxide, producing energy in the form of ATP. The process of respiration in Euglena occurs in the mitochondria, where glucose is broken down to release energy for the organism's metabolic activities.
All plants must have a way of getting energy. Most plants even underwater plants such as seaweed use photosynthesis and cellular respiration to get energy.
Eugena does not breathe in the sense that animals do. However, it does perform photosynthesis, which helps allow for the exchange of gases. Also, the permeable membrane surrounding the euglena allows for gaseous exchange.
Dark respiration refers to the process by which plants release carbon dioxide through cellular respiration during the night, in the absence of light. This process involves breaking down stored carbohydrates to generate energy for cellular functions when photosynthesis is not occurring.
All plants must have a way of getting energy. Most plants even underwater plants such as seaweed use photosynthesis and cellular respiration to get energy.
ATP is used for cellular respiration. It is not a product of cellular respiration.
Euglena is primarily aerobic, meaning it obtains energy through aerobic respiration in the presence of oxygen. However, euglena can also switch to anaerobic respiration in the absence of oxygen to generate energy.
Anaerobic respiration does not require oxygen, while cellular respiration does. Anaerobic respiration produces less energy compared to cellular respiration.
Some important questions to ask about cellular respiration include: How does cellular respiration produce energy for cells? What are the different stages of cellular respiration and how do they work? What role do mitochondria play in cellular respiration? How is cellular respiration related to the process of photosynthesis? What factors can affect the efficiency of cellular respiration in cells?
Oxygen is the difference! Cellular respiration requires oxygen, while cellular fermentation does not.
When it becomes dark, a plant continues to undergo cellular respiration to convert stored glucose into energy (ATP) for its metabolic processes. Unlike photosynthesis, which requires light, cellular respiration occurs continuously, utilizing oxygen to break down glucose. The byproducts of this process are carbon dioxide and water, which the plant can later use during photosynthesis when light is available again. Thus, even in darkness, plants rely on cellular respiration to meet their energy needs.
Because cellular respiration occurs in the presence of oxygen.
