Question

Cell membranes are structured so that molecules can pass in and out of the cell across them. While both plant and animal cells have membranes, plant cells also have cell walls surrounding their cells. Which of the following observations BEST supports the conclusion that molecules can cross cell walls as well?

A. every cell has its own nucleus
B. the chloroplasts would need light in order to work
C.the cell wall is directly outside of the cell membrane
D. water in the soil is used in photosynthesis

Answer 1

The answer is C. Cell wall is directly outside of the cell membrane.
Cell walls allow substances to pass through regularly but transport in and out of the cell is still regulated by the cell's membrane.

Answer 2

The correct answer will be-Option-C.

Step-by-step explanation:

The animal and plant cell show a structural difference as the plant cell exhibit a cell wall outside the cell membrane. The cell wall is made up of cellulose, a carbohydrate. The cell wall provides many functions to the plants as it acts as a structural entity as well as acts as a filter.

The cell wall is semi-permeable membrane present outside the cell membrane which allows the entry and exit of the molecules. The molecules have to pass the cell membrane also.

Thus, Option-C is the correct answer.
