• The stem acts like a highway, transporting water and minerals absorbed by the roots to the leaves and other parts of the plant.
• It supports the plant, allowing it to stand upright and reach sunlight, which is essential for photosynthesis.
• Without a proper stem, plants would struggle to distribute nutrients effectively, affecting their growth and health.

• Germination is the process where a seed begins to grow and develops into a baby plant.
• It starts when the seed absorbs water, swelling and breaking its outer shell.
• Temperature and light also play vital roles in this process.
• As the seed germinates, it develops roots, stems, and leaves, establishing itself as a new plant.
