Osmotic pressure in the phloem tissue allows phloem to move material according to the plant's needs. Give an example,

Explanation

### Step-by-Step Solution:

1. **Understanding Osmotic Pressure**: Osmotic pressure is the pressure required to prevent the flow of water across a semipermeable membrane. In plants, this pressure is crucial for the movement of nutrients and water in the phloem tissue.

2. **Role of Phloem Tissue**: Phloem is responsible for transporting organic compounds, particularly sugars produced during photosynthesis, from the leaves to other parts of the plant, such as roots and stems.

3. **Seasonal Changes and Nutrient Storage**: During different seasons, plants have varying needs. For example, in spring, plants require more energy for growth and reproduction. During this time, sugars and nutrients are stored in the roots or stem tissues.
