Is a virus a life form?
Viruses are considered by some biologists to be a life form, because they carry genetic material, reproduce, and evolve through natural selection, although they lack the key characteristics such as cell structure that are generally considered necessary criteria for life..
Are viruses alive Yes or no?
So were they ever alive? Most biologists say no. Viruses are not made out of cells, they can’t keep themselves in a stable state, they don’t grow, and they can’t make their own energy. Even though they definitely replicate and adapt to their environment, viruses are more like androids than real living organisms.
Are plants alive when eaten?
“Vegetables and fruits don’t die the moment they are harvested,” said lead researcher Dr. Janet Braam, Professor of Biochemistry and Cell Biology at Rice University in Houston, Texas. … Even after they’ve been harvested and cut from one another, their cells remain active and alive.
Is water alive Yes or no?
OLogy. All living things, from tiny cyanobacteria to giant blue whales , need water to survive. Without water, life as we know it would not exist. And life exists wherever there is water.

Is Water rare in the universe?
One of NASA’s guiding policies in the search for alien life is to “follow the water.” Water is fairly common in the universe, found everywhere from vast interstellar dust clouds to the orange-red fields of Mars, but most of this water is in the form of ice.
Is an apple dead or alive?
After apples are picked, they are still alive – they continue to carry out the chemical processes of a living plant, more or less, as they take in oxygen, create energy, and get closer and closer to ripeness.
Is Sun a nonliving thing?
For young students things are ‘living’ if they move or grow; for example, the sun, wind, clouds and lightning are considered living because they change and move. Others think plants and certain animals are non-living. … It is common for 5-7 year old students to have no conception of humans as animals.
