This question is a bit tricky because it's playing on our understanding of biological organization. Here's why:

* Cells are the smallest units of life. They are the building blocks of all living organisms.

* Tissues are groups of similar cells that work together to perform a specific function. Examples include muscle tissue, nervous tissue, and connective tissue.

Therefore, a cell is smaller than a tissue.

It's important to remember the hierarchy of biological organization:

1. Atoms

2. Molecules

3. Organelles

4. Cells

5. Tissues

6. Organs

7. Organ Systems

8. Organisms
