<span>It is true that the chromosome is the sex determiner for many species. There are two types of chromosome - X, which determines the female sex, and Y, which determines the male sex. Based on these chromosomes, the child will either be a man or a woman. There are some cases where a person has only one type of a chromosome, X, when they are considered to be an 'inter sex,' although resembling females more.

Answer:
The cell membranes controls what goes in and out by having protein channels that perform their role accordingly sometimes like funnels and like a pump in different cases.
When a channel open in the plasma membrane it allows molecule to pass through, in this case there is no requirement for energy so it is a passive transport.
Gases and food particles broke down in water must be assimilated and waste or harmful substance and molecules must be remove. For most cells, this type of selective transport of all materials all through the cell must happen through the plasma membrane.
