Explanation

**Step-by-Step Solution:**

1. **Understanding Essential Elements**: Essential elements are those that are crucial for the plant's growth, metabolism, and overall survival. They play specific roles in physiological processes and are necessary for the plant to complete its life cycle.

2. **Absorption of Various Elements**: Plants absorb a wide range of elements from the soil, including both essential and non-essential elements. While essential elements are required for metabolic functions, non-essential elements may be taken up by the plant but do not contribute to its vital processes.

3. **Examples of Non-Essential Elements**: Some elements, such as gold or selenium, can be absorbed by plants when they grow in certain environments, such as near radioactive sites. However, these elements do not play a role in the plant's metabolism or survival. Their presence in the plant does not indicate that they are essential for its growth.
