What is the direction, X, and function, Y, for the sugar molecules?
A.
Direction X is out; function Y is to provide chemical energy for the plant cell.
B.
Direction X is in; function Y is to provide heat energy for the plant cell.
C.
Direction X is out; function Y is to form more chlorophyll for the plant cell.
D.
Direction X is in; function Y is to form large sugar molecules for the plant cell.
D. Direction X is in; function Y is to form large sugar molecules for the plant cell.
The correct answer is D.
Direction X is in; function Y is to form large sugar molecules for the plant cell.
To determine the direction X and function Y for sugar molecules, we need to understand their role in the plant cell.
Sugar molecules are products of photosynthesis, a process that occurs in the chloroplasts of plant cells. During photosynthesis, plants use sunlight, water, and carbon dioxide to produce glucose (a type of sugar) and oxygen.
The correct answer is D. Direction X is in (into the plant cell) and function Y is to form large sugar molecules for the plant cell. After being produced in the chloroplasts, sugar molecules are transported throughout the plant to provide energy for various cellular processes. They can be used immediately for energy production or stored as starch for later use.
