Here is a worksheet on the Greek word root blasto/o. It means “cell, cell layer, immature cell, and “primitive bud.”
As you will see when you read the words under review, this isn’t a root that produces a lot of high-frequency words in English. But these words, if the the book from which the text for this document is drawn can be trusted, these words do turn up on the SAT. And if you have students planning careers in the health care professions? This is definitely a word root they should know.
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.
