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:
Both the arguments are valid.
Explanation:
Claire thinks enough food should should be produced for everyone, because the world's population is rapidly increasing. Don thinks the environment should be kept in mind, because our environment is getting ruined every second. Hence, both arguments are valid.
<span>Unlike vascular plants, non-vascular plants do not have tissue specialised fro transport of fluids, so</span> they cannot control the rate of water loss. However, they have simple tissues that can perform this function. They also lack in true leaves, seeds, flowers, and roots. They usually live in moist environment so they can absorb water more efficiently.
No, even after several days of incubation, you shouldn't detect any symptoms of microbial growth in a sterile medium.
<h3>What is the microbial growth in the sterile medium?</h3>
The deliberate introduction of germs into a sterile growing medium is known as immunization. When there are no living creatures present, a substance is sterile; undesirable bacteria are said to be contaminated. The use of aseptic procedures helps keep growing media from being contaminated. Reduce the amount of time that cultures and growth media are exposed to the outside world. Clean the work area both before and after each use. Avoid breathing or touching the stock cultures or sterile culture media. Before used, loops, needles, pipes, and other items should be sanitized. The tube caps should be held in your hand while inoculating and not placed on the table while using tubes.
