Which prefix means 'bud'?

• A. Blast-
• B. Ton-
• C. Lept-
• D. Therap-

Answer: (A)

In medical terminology, blast- denotes bud or sprout, coming from the Greek blastos meaning budding form. This prefix is used for early developmental stages and immature cells, which is why it fits the idea of a bud. You’ll see it in terms like blastocyst, blastomere, blastula, and blastema, all referring to early, budding stages of cells or tissues. The other options point to different ideas: ton- relates to pressure or tone, lept- means thin or slender, and therap- is tied to treatment or therapy. None of those convey the sense of a bud or sprout, so blast- is the correct choice.
