Ex Input:
Not all cells in a multicellular plant contain chloroplasts. All green parts of a plant contain chloroplasts—the chloroplasts, or more specifically, the chlorophyll in them are what make the photosynthetic parts of a plant green. The plant cells which contain chloroplasts are usually parenchyma cells, though chloroplasts can also be found in collenchyma tissue. A plant cell which contains chloroplasts is known as a chlorenchyma cell. A typical chlorenchyma cell of a land plant contains about 10 to 100 chloroplasts.

Ex Output:
What parts of plants have chloroplasts?

Detroit has four border crossings: the Ambassador Bridge and the Detroit–Windsor Tunnel provide motor vehicle thoroughfares, with the Michigan Central Railway Tunnel providing railroad access to and from Canada. The fourth border crossing is the Detroit–Windsor Truck Ferry, located near the Windsor Salt Mine and Zug Island.

The Detroit Salt Company mine has over 100 miles (160 km) of roads within.
