The primary function of the chloroplasts in a plant is to convert light
from the sun into glucose and energy in a process that is known as
photosynthesis. This energy is then used by the plant cells for
incredibly important functions such as growth and repair, so the chloroplasts are amongst the most necessary parts of any plant.
The structure of plasma membrane makes it selectively permeable allowing it to regulate the passage of substances into and out of the cell. Small nonpolar molecules can easily across the phospholipid bilayer of plasma membrane because it is hydrophobic. Polar molecules and ion cannot easily across the hydrophobic portion of plasma membrane because it is hydrophilic. Polar molecules and ions usually across the plasma membrane with the help of transport proteins.
I would say A.
B and C can be eliminated because they have to do with using resources more efficiently. Now we're down to A and D, and of the two, I'd say A is most plausible. Globalization is the connection of the world with each other. With all this technology, companies see endless possibilities to sell their products. They use more and more natural resources, which can deplete those resources quickly.
