Question

Which of the following would not be true for a typical plant cell?

1. a cell wall composed of cellulose, hemicelluloses, and pectin.
2. a large vacuole that regulates turgor pressure.
3. the absence of flagella or centrioles, except in the gametes.
4. a freely permeable cell membrane.

Answer 1

A typical plant cell has a selectively permeable, not freely permeable, cell membrane, which is the statement that would not be true from the given options. Therefore, the correct option is A.

Step-by-step explanation:

Of the four options provided, the statement that would not be true for a typical plant cell is the fourth option: 'a freely permeable cell membrane'. A typical plant cell has a cell wall composed of cellulose, hemicelluloses, and pectin, which lends structural support and protection to the cell. It also possesses a large central vacuole that plays a crucial role in maintaining turgor pressure, which gives the cell its shape and helps to support the plant. Additionally, plant cells usually lack flagella or centrioles, except in the gametes. However, the plasma membrane of plant cells is selectively permeable, not freely permeable, as it regulates the movement of substances into and out of the cell.
