Here is a worksheet on the Greek roots phyt/o and –phyte. They mean “plant” and “to grow.” If you teach in the hard sciences, particularly biology, this might be a useful document for you: these roots yield words such as chrysophyte, hydrophyte, and phytochrome among others.
If you find typos in this document, I would appreciate a notification. And, as always, if you find this material useful in your practice, I would be grateful to hear what you think of it. I seek your peer review.
