I may be wrong but I think it’s the second one. They speed up reactions, and there’s a certain enzyme for a certain reaction.
Plants need oxygen to survive , no oxygen mean the plant will diePlants do need oxygen to survive. They respire (take in oxygen, give off carbon dioxide) the same way that animals do. The difference is that during the day, plants also perform photosynthesis, in which they take in carbon dioxide and give off oxygen.Plants require oxygen for respiration to carry out their functions of water and nutrient uptake. In soil adequate oxygen is usually available, but plant roots growing in water will quickly exhaust the supply of dissolved oxygen and can be damaged or killed unless additional air is provided. A common method of supplying oxygen is to bubble air through the solution. It is not usually necessary to provide supplementary oxygen in aeroponic or continuous flow systems.Oxygen is vital ingredient in plant survival
Answer:
DNA tightly coils around proteins and condenses into chromosomes, which fit in the nucleus.
Explanation:
Answer:
The respiratory system works directly with the circulatory system to provide oxygen to the body. Oxygen taken in from the respiratory system moves into blood vessels that then circulate oxygen-rich blood to tissues and cells.
