Scientists searching for the blue-light receptor in plants isolated the gene for a membrane protein that becomes phosphorylated in response to blue light. They inserted the gene into insect cells and exposed the cells to blue light. Why did the scientists use insect cells instead of plant cells?

Insect cells are easier to work with than plant cells.

Because the insect cells do not contain any other plant proteins, the researchers were able to determine that the identified plant gene truly encoded a blue-light photoreceptor.

Plant cells cannot be grown in a laboratory.

Insect cells respond to blue light in the same way as plant cells do.
