What are plant hormones?
Almost every element of plant growth and reaction to its environment is regulated by plant hormones. Numerous plant hormones play important roles in the interactions between plants and helpful microorganisms because they are active at extremely low concentrations and have precise spatial control of synthesis and response.
The "The Role of Plant Hormones in Plant-Microbe Symbioses" special issue offers fresh information on the functions of hormones produced from both the plant and the microbial partner in symbiosis establishment and communication. This includes the close symbioses that the majority of terrestrial plants have with arbuscular mycorrhizal (AM) fungi, as well as the more recently acquired nodulation—symbioses between a select group of plants in the fabid clade and nitrogen-fixing bacteria.
The articles in this special issue also look at how hormones affect how plants interact with ectomycorrhizae, endophytic bacteria, and fungi, and helpful microorganisms that stick to the surfaces of the leaves and roots. Many hormones can interact with one another in addition to acting directly to regulate the growth of these symbioses, and these intricate networks are just beginning to emerge.
Therefore, various plant hormones are used commercially.

Answer:
When a volcano erupts particles of rock and ash are released into the atmosphere after this water droplets form around?
When a volcano erupts, particles of rock and ash are released into the atmosphere. After this, water droplets form around the rock and ash particles and fall to Earth as rain. The rainwater helps plants grow. Which scenario describes an interaction between two of Earth's spheres?
Explanation:
The spheres of Earth that interact in this scenario are the geosphere, hydrosphere, and biosphere.
The geosphere, which makes up the solid Earth, spews rock and ash particles into the atmosphere during a volcanic eruption. These ascenting particles come into contact with the hydrosphere, or the water systems of Earth. Rain is created when water droplets gather around the particles. This rain, which has been enhanced with minerals from volcanic material, falls to the biosphere and fosters the growth of plants.
The interplay between the geosphere, hydrosphere, and biosphere demonstrates the complex interrelationships between Earth's constituent parts, demonstrating how changes in one sphere can have an effect on others, eventually influencing the environment and sustaining life.

5. Why do you think it's important to look at the impact on the ecosystem as a whole, instead of just the individual"?
Answer:
Ecosystem Services are the benefits nature provides to human well-being. The term is frequently thrown around in academic circles, but why should you care about them?
Although the term is quite new, our connection to nature is not. We depend on nature for our survival - without healthy ecosystems, our drinking water isn’t clean nor is the air we breathe. We also enjoy nature... studies show that people who spend time in nature tend to be happier than those that don’t. It can even act as a natural anti-depressant. With industry and urban sprawl expanding at unprecedented rates, Ecosystem Services attempt to translate the benefits we receive from nature into economic terms so we can better understand the trade-offs we are making between nature and industrial development.
This brings us to the reasons why we feel Ecosystem Services are important to each and every person:
1. Boundless Benefits
Understanding nature in economic terms, while not perfect, allows us to put everything into the same comparison unit. Despite nature being such an integral part of the human existence, it is sometimes an afterthought in today’s economy. Nature and money are often on competing terms, so to make a more level playing field, environmental economists have tried to bridge this gap by placing a monetary value on the benefits nature provides.
A recent study estimated the combined benefits of nature to people at well over $100 USD trillion per year. To put this in perspective, the top 50 most profitable companies globally combine to make just under $10 USD trillion per year.
Valuing nature in a way that can speak to decision makers, may help promote conservation efforts in the future. It brings nature back into the cost-benefit discussion in a way that can be easily understood.
2. The Foundation For Sustainable Development
Ecosystem Services help measure the true cost of industrial development. Often, the impact industrial development has on the economy and job creation overshadows the cost it will have on surrounding lakes, forests, keystone species, and so on. Assigning a dollar value to these lakes and forests, and the Ecosystem Services they provide, helps adjust the cost benefit analysis by evaluating the negative effects development will have on the natural environment.
Companies have also started to use Ecosystem Services in conservation offset planning, where they can buy and sell credits to offset a development or set aside land to meet a specific offset. Sustainable development supports the maintenance of a healthy economy while also protecting the ecological process for future generations.
3. Essential For Our Survival
Whether you live in rural Newfoundland or downtown Los Angeles, your dependence on Ecosystem Services is the same. As a society, we depend on healthy ecosystems to do many things; to purify the air so we can breathe properly, sequester carbon for climate regulation, cycle nutrients so we have access to clean drinking water without costly infrastructure, and pollinate our crops so we don’t go hungry. As the world’s population continues to grow, so too does our dependence on healthy ecosystems to provide the necessities essential to our survival.
Don’t we all want to leave the planet in a good condition for our successors? Ecosystem Services valuation and assessment is one way to help make this happen. By clearly understanding their value, we can make the best and most informed decisions about how to manage our landscape to ensure this value isn’t lost.

How waste is removed from plant body ?
Answer:
Living organisms sustain life, based on certain life processes. These life processes help to regulate their daily activities. Excretion is one among them. The metabolism takes place in the cells of living organisms resulting in both useful and toxic products. The accumulation of toxins may harm the organism. Thus, the living organisms remove all these metabolic wastes from their body and this process is called excretion. Different organisms follow different modes of excretion. Let’s have a glance at excretion in plants and how excretion in plants is different from that of animals.

Long before the structure of DNA was solved, the physicist Erwin Schrodinger suggested that the three-dimensional arrangement in some polymer had to explain the two main properties of heredity: 1) the stability of life, such that traits were passed faithfully from generation to generation, and 2) the mutability of life, such that traits could change. How did Watson and Crick’s structure explain those two properties?
Watson and Crick's model explained mutability because bases pairs can suffer changes (mutations) during DNA replication. Moreover, this model also explained stability because DNA strands are held together by hydrogen bonds.
Deoxyribonucleic acid (DNA) is a double helix molecule composed of two long chains of four types of nucleotides, each containing one different nitrogenous base, i.e., Adenine, Guanine, Cytosine and Thymine.
In Watson and Crick's model, both DNA strands are held together by hydrogen bonds between nitrogenous bases on opposite DNA strands, thereby providing stability to the DNA molecule.
In DNA, Guanine always pairs with Cytosine by three hydrogen bonds, while Adenine always pairs with Thymine by two hydrogen bonds.
Moreover, Watson and Crick suggested that mutations could occur as a consequence of a base occurring very infrequently in one of the less likely tautomeric forms during DNA replication, thereby also explaining the mutability of life.
