Epipremnum aureum - Wikipedia
a
By actively transporting ions across the cell membrane
b
By generating ATP through photosynthesis
c
By regulating gene expression within the cell
d
By regulating the cell's pH balance
b. By generating ATP through photosynthesis
Epipremnum aureum, also known as the golden pothos or devil's ivy, is a plant species that exhibits its characteristics and functions primarily through photosynthesis. Therefore, option b, "By generating ATP through photosynthesis," is the correct answer for how Epipremnum aureum obtains energy.
Option a, "By actively transporting ions across the cell membrane," is not a primary mode of obtaining energy for Epipremnum aureum. While active transport may occur in the plant's cells, it is not the main source of energy production.
Option c, "By regulating gene expression within the cell," is not applicable to plants such as Epipremnum aureum. Gene expression is more pertinent to organisms with complex cellular processes, such as animals and humans.
Option d, "By regulating the cell's pH balance," is not a primary function of Epipremnum aureum. While plants have mechanisms to regulate pH within their cells, it is not directly related to energy production.
In summary, Epipremnum aureum obtains energy primarily through photosynthesis, option b.
The options provided seem to be related to the question of how Epipremnum aureum, also known as the Golden pothos or Devil's ivy, obtains energy.
Firstly, option b, "By generating ATP through photosynthesis," can be eliminated because Epipremnum aureum is not a photosynthetic plant. It belongs to the family Araceae, which includes plants that mostly rely on their ability to enhance nutrient uptake from the soil rather than generating energy through photosynthesis.
Next, option a, "By actively transporting ions across the cell membrane," is also not a correct answer. While ion transport is a fundamental process in many plant cells, the energy for this transport is primarily derived from ATP produced through other means.
That leaves us with two remaining options: c) "By regulating gene expression within the cell" and d) "By regulating the cell's pH balance."
Epipremnum aureum obtains energy through the process of cellular respiration, which occurs within its cells. This process involves breaking down organic molecules to release energy in the form of ATP. The regulation of gene expression plays a role in the production of the necessary enzymes for cellular respiration and therefore contributes to obtaining energy, making option c a potential answer.
Regarding option d, "By regulating the cell's pH balance," while pH regulation is important for the cell's overall functioning, it is not directly related to obtaining energy.
To summarize, the correct option for how Epipremnum aureum obtains energy is most likely c) "By regulating gene expression within the cell."
