Check all the information about a Cell Wall (check all that apply).
A. Is semipermeable (allows certain things to enter and exit a cell)
B. Helps keep the plant cell SHAPE
C. A layer for additional protection
A. Is semipermeable (allows certain things to enter and exit a cell)
B. Helps keep the plant cell shape
C. A layer for additional protection
To check all information about a cell wall, we can assess each option individually:
A. Is semipermeable (allows certain things to enter and exit a cell): This statement is incorrect. A cell wall is permeable, meaning it allows certain substances to pass through, but it is not semipermeable like a cell membrane.
B. Helps keep the plant cell SHAPE: This statement is correct. The cell wall provides structural support and helps maintain the shape of a plant cell.
C. A layer for additional protection: This statement is correct. The cell wall acts as an additional protective layer, providing a barrier against external threats such as pathogens and physical damage.
Therefore, options B and C are correct when discussing the information about a cell wall.
To check all the information about a cell wall, we can break down each option and explain how to find the answer.
A. Is semipermeable (allows certain things to enter and exit a cell): To determine if the cell wall is semipermeable, you need to investigate the characteristics of the cell membrane, not the cell wall. The cell membrane is responsible for regulating the passage of substances in and out of the cell. The cell wall, on the other hand, provides structural support and protection but does not play a role in selective permeability. Thus, the cell wall is not semipermeable.
B. Helps keep the plant cell shape: This statement is true. The cell wall provides rigidity and support to plant cells, helping them maintain their shape by preventing them from collapsing or bursting under pressure.
C. A layer for additional protection: This statement is also true. The cell wall acts as an additional layer of protection for plant cells. It helps protect the cell from mechanical damage and provides a physical barrier against pathogens.
In summary, the correct options are B and C. The cell wall helps keep the plant cell shape and acts as a layer for additional protection.
