the answer is cellular membrane
photosynthesis
Edited answer:
Cell wall, also known as turgor pressure
a plant stands up straight because it is reaching to the light source which is usually straight above it. it will bend to the light if the source is not above it
In chemistry it's standard temperature and pressure
RTP stands for room temperature (in chemistry)
Pa is the abbreviation of the SI unit pascal which is a measurement of pressure.
This is at least an unproven theory (or should I say 'feeling' or 'fantasy').So as long as this stands I'd say NO.

The line stands for "on" and the circle stands for "off".
H stands for high such as heat and that is the definition edit by 2797jake: I believe it means a high pressure area and L for a low pressure area. On weather maps the H stands for high-pressure and the L stands for low-pressure.
M.A.D.D. stands for mothers against drunk driving
ATM stands for atmosphere, such as in atmospheric pressure.
obscurant
I know that usp stands for the United States Pharmacopedia but has nothing to do with medicine. bp stands for blood pressure which can be maintained with blood pressure medicine.
polysaccharide
because cell walls of the plant cells makes the plant stands straight
Millibars.
