Although only a small portion of water absorbed by the plant is used in photosynthesis, a shortage of water does affect the rate photosynthesis occurs. Even a slight deficiency of water results in significant reduction in the crop yield. The lack of water not only limits the amount of water, but also the quantity of carbon dioxide available for photosynthesis. This is because in response to drying the leaves close their stomata in order to conserve water being lost as water vapor through them. Care should be take to assure that both optimal oxygen and water are available to the roots at all times.
Answer:
Carbohydrates contain the elements of carbon, hydrogen, and oxygen, and only those elements with a few others.
Lipids/fat contain hydrocarbons and make up the building blocks of the structure and function of living cells. Examples include: fats, oils, waxes, and certain vitamins (such as A, D, E, and K).
Proteins contain carbon, hydrogen, and oxygen like the carbohydrates and lipids, but they also contain nitrogen and often sulfur and phosphorus.
Nucleic Acids are the large biomolecules that are essential to all known forms of life. The term nucleic acid is the overall name for DNA and RNA. Consisting of Nucleotides, which are the monomers made of three components: a 5-carbon sugar (a phosphate group and a nitrogenous base).

Scientific laws explain phenomena that have been proven to be true by the scientific community. In general, theories explain how a phenomenon occurs, whereas laws predict what will happen in a particular scenario based on an equation.
A scientific law foretells the outcomes of particular initial circumstances. It may tell you what color hair your unborn child would have or how far a baseball will travel when launched at a specific angle. In contrast, a theory seeks to offer the most plausible justification for why events take place the way they do.
The five most well-known scientific laws are:
- Bernoulli's law of fluid dynamics.
- Dalton's law of partial pressures.
- Hooke's law of elasticity.
- Fourier's law of heat conduction.
- Archimedes' Principle of Buoyancy.
