The movement of molecule across a typical plant cell ( about 50 `mum` ) takes place approximately ______ seconds.

Explanation

To solve the question about the time taken for a molecule to move across a typical plant cell of about 50 micrometers, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Micrometer**:
- A micrometer (µm) is a unit of length in the metric system. It is equal to \(10^{-6}\) meters.
- Therefore, 50 micrometers can be converted to meters:
\[
