The correct Answer is:
### Step-by-Step Solution: 1. **Understanding Growth Rings**: - Growth rings are layers of wood that are added to the bark of trees during a single growth period. Each ring represents one year of growth. 2. **Formation of Growth Rings**: - During the growing season, trees add new layers of wood. However, if there are adverse conditions like drought, it can affect the growth rate. 3. **Annual Rings**: - Typically, one growth period results in one annual ring. However, under certain conditions, such as drought, trees may produce more than one ring in a single year. These additional rings are referred to as pseudo-annual rings. 4. **Cork Cambium Activity**: - The formation of these rings is influenced by the activity of the cork cambium, which is a layer of cells that contributes to the growth of the bark. 5. **Location of Growth Rings**: - Growth rings occur in the extracellular region of the plant, specifically in the vascular cambium, which is responsible for secondary growth in plants. ### Final Answer: Growth rings occur in the extracellular region of trees, specifically due to the activity of the cork cambium. ---
