Question

The cell is the fundamental unit of life and requires certain basic functions, including:

1. A boundary that distinguishes inside from outside the cell yet allows materials to enter or leave the cell.
2. An "engine" to capture energy from the environment and convert it to a form useful to the organism.
3. A genome that can be transmitted to the next generation and is stable, but able to change.
4. A way to change in response to environmental changes, over both a short (individual organism) and long (generational) time frame.

Answer 1

Step-by-step explanation:

A boundary that distinguishes inside from outside the cell yet allows materials to enter or leave the cell.

The cell needs a barrier for protection, rigidity and also for easy transportation.
