That molecule is called Geosmin. It is mainly produced 1 by Actinomycetes such as Streptomyces; filamentous bacteria that live in soil. Other organisms also produce geosmin: Cyanobacteria Certain fungi An amoeba called Vanella A liverwort It is an intracellular metabolite and cell damage is the primary reason attributed to its release. However oxidant ...

I've worked on a couple of these for biofuel production. The answer varies widely according to plant P and how well studied plant P is. In terms of what data is used, it includes but is not limited to: temperature, insolation, length of the day, cloud cover, rain, soil composition, soil type, soil density, other local effects like wind or pests, altitude, ...

Hydrogen carbonate is an indicator commonly used for testing photosynthesis. It shows changes in carbon dioxide concentration in the air. You would set up the plant in a sealed system next to a tray of hydrogen carbonate indicator solution and observe the colour change.

In biology phosphorylation marks the addition of inorganic phosphate groups to proteins or other organic molecules. The phospho-group usually comes from ATP which is converted into ADP in this process. In the context of the Calvin Cycle there are two positions where molecules get phosphorylated. The first is the phosphorylation of 3-phosphogylcerate to ...

With arbitrarily broad meaning of "processed", yes. If absolutely nothing else, elemental purification and inorganic synthesis of something chemically resembling meat in nutrition is possible. Prohibitively expensive and stupid, yes, but possible. So then the question becomes exactly how much processing you need to do. Without clear bounds on that question ...

Forever no. For thousands of years yes. And not only plants, other organisms have what is called biological immortality. Look here for some examples https://en.m.wikipedia.org/wiki/List_of_long-living_organisms

Of course it is possible for a carnivore to live with a vegetarian diet. Technically you could come up with a complete meal out of vegetables and make a carnivore pup live with it. Dogs and cats are good example of it. They can learn to eat vegi-processed food and as far the nutrients needed are present they will grow and live well. To make them eat raw ...

The answers to these questions often boil down to "what do you mean by live forever?". You've included vegetative cloning, so I infer that counts as one living organism for your purposes. In that case, the answer is absolutely. Pando is at least 10 thousand years old and only getting larger. The Cavendish banana is about 150 years old, but produces at ...

What does it mean for an element to be mobile or immobile in plants? Generally speaking, mobile elements are those that can be moved from older to newer tissue in the plant, while immobile ones cannot be. For example, calcium is incorporated into the cell wall, so it is immobile; it cannot be relocated later. Plants with a deficiency of mobile elements ...

Meristems in plant's kingdom are functionally similar to stem cells in animal kingdom, even you can see it in their names, meriSTEMs & STEM cells ,stem cells are more flexible,okay going back to meristems ,buds are complex of apical or lateral meristems which are covered by special kind of leafs according to enzymatic change,photoperiod and climate ...

The uptake system in plants is much more complicated, as Mr.Baily opened the anatomy and structure of root I will only explain the uptaking system. When plant absorbs water it absorbs some elements too, but there is a broblem which is soil particles as the clay is a cloidical substance of soil wich does contain negative charge and most of essential elements ...

Welcome to Biology.SE! About your title Let me first react to your title: Viruses selected by evolution. Evolution is any process of genetic (and eventually phenotypic) change in a population through time. Selection (Natural Selection for example) is one of such process. Genetic drift is another such process. So, evolution don't select viruses. Viruses ...

One thing to remember when you uproot a plant is that some of the smallest structures break off most readily. What you will usually see after uprooting the plant are the largest parts of the root structure, but there are often smaller parts which have broken off. Root structure is highly variable, but the general idea is that one or more primary trunk-like ...
