Hello. I am a 13 year old kid who did this experiment for my science fair, so my answer may not be correct but is quite distinctive in the results. I had three plants. One that was kept away from radio waves as much as possible, one that was sometimes exposed to radio waves from a guitar amplifier, and one that had the aerial of an ordinary FM radio below its leaves at all times. I kept the experiment going for 25 days, and I tried to keep everything else the same.
In the end, the radio waves plant grew the most, then came the control plant (radio wave sometimes), then in last place the natural plant. I hope this was helpful, but I understand if you do not rely on this answer. If you really wanted to, you could do this at proffessionally controlled conditions with an oscillator and everything. :-)

What effect do radio waves have on living cells?

Why does fresh plant material block radio waves?
Radio waves can be blocked (reflected) or attenuated (partially reflected or absorbed) by anything that conducts electricity. A thin sheet of aluminum can completely block (reflect) radio waves. They simply cannot penetrate it. Salt water (as in the ocean) permits radio waves to penetrate only a very short distance. Similarly, living plant material contains water and dissolved ions (the plant's "blood" or the plants food, if you want to look at it that way). This makes the plant something of a "conductor" of electricity. Now to the nut inside the shell of this answer. When radio waves (electromagnetic energy) encounter a conductor, something happens. The frequency of the radio waves, their amplitude, and the "nature" of the conductor will result in a varying degree of interaction. What happens is that the radio waves stimulate microcurrents within the conductive material (the foil, the salt water, the plant with its moisture and ions, whatever). This interaction reflects or absorbs the energy (to a greater or lesser degree) of the incoming radio wave. The microcurrents don't destroy plant tissues because the power contained in the radio wave is very low (microvolts per meter, and usually less). Certainly if a plant is "right on top" of an electromagnetic source, it will take some heat from the radiated energy. But as to the effect of "regular" radio waves, the damage is not noticable, and the signal will be damped or attenuated by interaction with the plant.
Does mechinal waves have radio waves?
no, mechanical waves are not radio waves
Why do radio waves diffract around building's while light waves do not?
Light waves do diffract, but the effect is very very small. In general diffraction effects are important when the object interacting with the wave has dimensions that are comparable to the wavelength of the wave. Light waves have much shorter wavelength compared to the radio waves. Hence the effect. (It should also be noted that radio waves penetrate buildings much better than light waves, but that leads to a more nuanced discussion of diffraction effects.)
How are electromagnetic waves different to radio waves?
Radio waves ARE electromagnetic waves.

What happens when your nice to a plant?
If you meant be nice to a plant by using language, most likely nothing will happen. If you put some type of electronic that makes loud sound such as speakers next to the plant, the radio waves might effect the plant in some way. Try an experiment.
What effect does heat have on an experimental plant?
In general, heat waves do not have any effect on the biomass of a plant in an experiment. The heated water or water from a microwave also does not affect the plant.
Does mechinal waves have radio waves?
no, mechanical waves are not radio waves
Are radio waves transverse waves or longitudinal waves?
Transverse. Radio waves are electromagnetic waves, which are transverse.
Does music affect bactria?
The sound waves of the music could effect the growth of the bacteria.

How are electromagnetic waves different to radio waves?
Radio waves ARE electromagnetic waves.
Are radar waves visible?
No. Radar waves are one category of radio waves. Think of all the radio waves that are all around you right now . . . AM radio, FM radio, police and fire radio, highway patrol radio, taxi radio, television picture and sound radio waves, cellphone radio waves, garage-door-opener radio waves, bluetooth radio waves, WiFi waves, microwaves ... and you can't see any of them ! Radar waves can easily be there in the group.
Radio waves harmful effect?
That's not a question, improve your sentence structure and I'll improve my answer
How are radio and television waves added to em radio waves?
by changing the amplitude or frequency of the radio waves.
