I would say that the answer is D.
Answer:
It is pertinent to understand what hypertonic, hypotonic, and isotonic solution means before setting out to explain how a cell reaches equilibrium in each type of solution.
A hypertonic solution is one whose solute concentration is higher than that of the sap of a cell that is immersed in it.
A hypotonic solution is one with the same solute concentration as that of the sap of the cell immersed in it.
An isotonic solution has a lower solute concentration than that of the sap of the cell immersed in it.
In biological systems, water molecules move by osmosis from the region of higher water potential or lower concentration of solutes to the region of lower water potential or higher concentration of solute. An equilibrium is reached when there is no net movement of water between two sides. Hence;
A cell placed in a hypertonic solution will lose water to the surrounding solution until an equilibrium is reached. This means that such a cell will end up shrinking (wilting) or even dying due to loss of water from the cell sap.
A cell placed in a hypotonic solution will gain water from the surrounding solution until there is no net movement of water anymore. Such a cell might become turgid or even burst out its cell content.
A cell placed in an isotonic solution will neither gain nor lose water because the cell sap and the surrounding solution have equal solute concentrations.
Explanation:
when a plant takes in sunlight to make glucose
The correct answer is C4 plants.
A plant that cycles carbon dioxide into four-carbon sugar components to get into the Calvin cycle is known as a C4 plant. These plants are very effective in dry, hot climates and produce ample energy. Various foods one consumes are C4 plants like pineapple, corn, and sugar cane.
In the C4 plants, at the start carbon fixation occurs in the mesophyll cells and the Calvin cycle occurs in the bundle-sheath cells. The PEP carboxylase combines with an incoming molecule of carbon dioxide to the three carbon-molecule PEP, generating a four carbon molecule, that is, oxaloacetate.
I have not learned that yet i wish i could help so sorry though good luck
