Xylem is the advanced dead material, however, the cell contents are not. Phloem, though not with the heart, is the breathing material.
Answer is above.

Answer:
The given situation is an example of <u>density dependent factor</u>.
Explanation:
The density dependent factors are the factors that regulate the growth of a population. It is defined as the factors whose effects on the growth or size of a given population vary with the population's density. The various types of density dependent limiting factors are diseases, migration, safe drinking water, food availability, migration etc.

So we know that to transport materials in or out of the cell, we need to have access to both the inside and outside of the cell. This would require that the protein be a transmembrane protein that reaches both the inside and the outside of the cell.
So in this case, let's look at pore proteins. These are proteins that cross a membrane and act as a pore for the materials that need to cross the membrane.
One example of a pore protein is an aquaporin. These proteins aid in the transport of water into or out of a cell.
Therefore, the answer to your question is: A) Pore proteins.
