Answer:
A. Oxygen ( for animals )
B and C ( for plants )
Explanation:
Cellular nutrients come in many forms, including sugars and fats. In order to provide a cell with energy, these molecules have to pass across the cell membrane, which functions as a barrier — but not an impassable one. During cellular respiration, oxygen is needed. Carbon dioxide is the product of cellular respiration.
In the event you are referring to plants, then both water and carbon dioxide are needed for photosynthesis.
Oxygen is required by all cells in order to function properly. Thus, the correct option is A.
Cells may be defined as the building blocks of living organisms. They are considered the basic structure and functional unit of life. All living beings are made up of cells.
Antony von Leeuwenhoek discovered the living cell for the very first time in 1674 with the help of an improved microscope in Pond water.
Cells require oxygen because they have the ability to break down food particles in the presence of oxygen to derive energy for metabolic activities. This process of breaking down food in the presence of oxygen is known as cellular respiration.
This is because oxygen functions as a final electron acceptor in the electron transport chain to synthesize an energy molecule known as ATP.
Therefore, Oxygen is required by all cells in order to function properly. Thus, the correct option is A.
