In producing transgenic plants, cells called protoplasts are often used. Protoplasts are plant cells from which the cell wall has been removed. Why would the cell wall need to be removed?


A) The foreign DNA enters the cell through self-healing holes in the membrane but it could not pass through the cell wall.
B) The cell wall prevents the transgenic cell from growing into a mature plant.
C) The cell wall makes it difficult for the biotechnician to determine if the foreign DNA has been incorporated into the cell's genome.
D) The cell wall prevents the microinjection of foreign DNA into the cell because the needle cannot pass through it.
E) The foreign DNA passes through the plasmodesmata of the plant cell, which is blocked by the cell wall.
