All BUT one is a function of the cell wall. Which one is NOT a function of the cell wall?

Question 1 options:

provides support

regulates the passage of materials

transfers genetic materials

provides protection

transfers genetic materials

The function of the cell wall that is NOT listed is "transfers genetic materials."

To determine which option is not a function of the cell wall, we need to understand the functions of the cell wall and then analyze each option.

The cell wall is a rigid layer that surrounds the cell membrane in many organisms. Its main function is to provide structural support and protection to the cell. It helps in maintaining the shape of the cell and prevents it from bursting under osmotic pressure. Additionally, the cell wall regulates the passage of materials into and out of the cell, allowing certain substances to pass through while blocking others.

Now let's analyze each option:

1. Provides support: This is a function of the cell wall, as mentioned earlier. It gives the cell its rigidity and structure.
2. Regulates the passage of materials: As stated, this is also a function of the cell wall. It acts as a selective barrier, controlling the movement of substances.
3. Transfers genetic materials: This option refers to the transfer of genetic materials, which is not a function of the cell wall. Genetic materials, such as DNA, are typically transferred through processes like replication, transcription, and translation, which occur within the cell but not directly involving the cell wall.
4. Provides protection: Like support, protection is a function of the cell wall. It acts as a physical barrier against external factors, such as mechanical damage or pathogen invasion.

Based on the analysis, the function that is not associated with the cell wall is "transfers genetic materials" (Option 3).
