Binghamton Press & Sun-Bulletin  |  April 20, 2018
"There are more than 300,000 different kinds of plants, including plants that live in the ocean, like kelp; and plants that live in the desert, like cactuses. There are microscopic plants, like algae; and gigantic plants that can be very old, like redwood trees. But no matter what, all plants need the same four things to grow: water, air, sunlight and nutrients."
