preview biology vocabulary
two key terms from this chapter share the same word part. read the
definitions and guess what the word part means.
term | definition | what i think the word part means
aerobic | describes reactions that do not require oxygen |
aerobic | describes reactions that do not require oxygen |

Explanation:

The two terms "aerobic" and "anaerobic" share the word part "aer" (or "aero"). Looking at their definitions: "aerobic" needs oxygen, "anaerobic" doesn't. The prefix "an - " means "without", so the root "aer" likely relates to oxygen or air (since oxygen is in air). So the word part (root) "aer" probably means "oxygen" or "air" (related to oxygen - based processes).

Answer:

The word part (root) likely means "oxygen" (or "air", related to oxygen - involving processes). The shared word part is "aer" (from "aerobic" and "anaerobic"), and from the definitions (one needs oxygen, one doesn't), we infer "aer" is about oxygen.
