Multiple Choice

In the context of cell communication, what is the primary difference between adherence and colonization?

Adherence involves the movement of cells towards a chemical stimulus, while colonization is the formation of a protective biofilm.

Adherence is the release of signaling molecules by cells, whereas colonization is the response to these signals by other cells.

Adherence refers to the initial attachment of cells to a surface, while colonization involves the growth and multiplication of cells after attachment.

Adherence is the process of cells communicating through chemical signals, whereas colonization is the exchange of genetic material between cells.

Verified step by step guidance

Understand the context of cell communication, which involves how cells interact with each other and their environment.

Identify the concept of adherence: it refers to the initial attachment of cells to a surface. This is a crucial first step in many biological processes, including infection and tissue formation.

Recognize the concept of colonization: it involves the growth and multiplication of cells after they have attached to a surface. Colonization can lead to the formation of structures like biofilms, which are communities of microorganisms.

Differentiate between adherence and colonization: adherence is about the initial attachment, while colonization is about subsequent growth and multiplication.

Consider the implications of these processes in various biological contexts, such as infection, where adherence might be the first step in a pathogen establishing itself in a host, followed by colonization leading to disease progression.
