Check out the Wikipedia article for strain and some of the sources in it where the term is used: A strain is a low-level ...

The second paragraph in the question describes two solutions separated by a semipermeable membrane (a membrane that allows water through, but not anything dissolved in the water). As it says, in those conditions, water will move from the section with low osmotic pressure to the solution with high osmotic pressure. Osmotic pressure, like other colligative ...

The definition in your first paragraph doesn't match your understanding in the second. If osmotic pressure is high in "A" relative to "B", you would have to apply a physical pressure to "A" to prevent solvent moving from B to A. If there is no such pressure applied, then solvent does move from B to A. The osmotic pressure and physical pressure are separate ...

Yes, increase in CO₂ concentration increases the rate of photosynthesis in plants. The rate of photosynthesis is linealy proportinal to CO₂ concentration in range up to 225ppm and slowly increases range 225-650ppm.[Limiting Factors in Photosynthesis, Plant Physiol. (1984) 75, 82-86] (Now CO2 concentration is about 400ppm). You can read more in Educational ...
