Where would the following structures be found in a cell? microtubules, thylakoids, `F_0 - F_1` complex, ribosomes, nucleolus.

Explanation

To answer the question regarding where the following structures are found in a cell: microtubules, thylakoids, F0-F1 complex, ribosomes, and nucleolus, we can break down each structure and its location step by step.

### Step-by-Step Solution:

1. **Microtubules**:
- Microtubules are tubular structures made from the protein tubulin.
- They are primarily found in the **cytoplasm** of eukaryotic cells, except for molds and amoebas.
- They are also present in specialized structures such as **centrioles**, **spindle fibers**, **flagella**, **cilia**, and in the **chromosome fibers** during cell division.
