Question

Quizplus · Accepted Answer

A cell is the lowest level of biological organization that can perform all the activities required for life, including energy production, responding to stimuli, and reproduction. While organelles have specific functions within a cell, they cannot carry out all the activities required for life on their own. Tissues, organs, and organ systems are all composed of multiple cells working together and are therefore not the lowest level of biological organization that can perform all the activities required for life. And while an organism is capable of performing all the activities required for life, it is made up of multiple cells and is not the lowest level of organization.
