According to Petronus's (2016), for photosynthesis to occur, a cellular component like the pigment must be present because it gives plants their colour and traps sunlight in the process. The light spectrum, which is employed in most virtual labs for experimentation, has a tendency to have both long and short waves that contain various colours. Chlorophyll helps the photosynthesizing plant capture both blue and red light, according to Couto.

define hypertonic, hypotonic and isotonic. is it possible for a solution to be both hypertonic and hypotonic? why or why not? explain what happens to an animal cell in a hypertonic solution? a plant? why is it different? what happens in a hypotonic solution? (create an illustrated representation of hypertonic, hypotonic and isotonic solutions using any plant or animal cell to help distinguish between the three types of environments.)
If surrounding solution has higher solute concentration compared to inside the cell, then it is called hypertonic solution. A hypertonic solution has a higher concentration of solutes. If surrounding solution has high solvent concentration compared to the inside of the cell, then it is called hypotonic solution. A hypotonic solution has a lower concentration of solutes than cytoplasm of cell. If both surrounding solution and solution inside the cell has same concentration of solvent and solute, then it is known as isotonic solution.
A solution can be both hypertonic and hypotonic depending on type of cell or substance kept in solution. If cell has more solutes than solution then it may swell and if it has less solutes than solution then it may shrink.
If animal or plant cell is kept in hypertonic solution that is solution with higher solute concentration than water molecules will move outside of the cell from inside of the cell ie; exosmosis will take place. Due to this reason, both animal as well as plant cell will shrink. Plant cell is said to become plasmolysed.
In hypotonic solution, animal and plant cell will swell as solution has lower solute concentration than inside of the cell present in solution. Animal cell will swell and ultimately burst ie cell will lysed but, plant cell will not burst it will swell and develop turgor pressure. Hence, plant cell becomes turgid in hypotonic solution.

why is fructose toxic to liver cells, but not muscle cells, in individuals with a defect in the enzyme aldolase b?
Fructose is toxic to liver cells, but not muscle cells, in individuals with a defect in the enzyme aldolase, because muscle cells employ hexokinase to convert glucose to glucose-6P, which cannot be further metabolized, liver cells cannot.
In the second stage of the metabolism of fructose, aldolase B is in charge of converting the compound fructose-1-phosphate into glyceraldehyde and dihydroxyacetone phosphate. Aldolase B is also involved in the breakdown of the simple sugar glucose, but to a lesser extent. The lack of the enzyme aldolase B is a defining feature of the autosomal recessive condition known as inherited fructose intolerance.
Fructose-1-phosphate is broken down into glyceraldehyde and dihydroxyacetone phosphate by the crucial enzyme aldolase B. Phosphate depletion and fructose 1-phosphate buildup in the liver are symptoms of aldolase B deficiency. As a result, gluconeogenesis and glycogenolysis are suppressed, which inhibits the synthesis of proteins and causes liver failure.
