Sunflowers – Planting to Harvest
Planting
The seed is about half an inch long. It has a hard, striped covering. The covering protects the soft inside (the part that is tasty to eat). What the covering protects, and what you like to eat, is the food that the sunflower needs to begin to grow into a plant. Let’s plant the seed and watch it change and grow! In the spring, when the ground is warm, and the soil is soft, you can plant your seed. The seed needs to be buried in the soil where it can be warmed by the sun, watered by the rain, and fed by nutrients and oxygen trapped in the soil. Now underground, the hard covering of your seed splits open, and a little, white root appears! The root is the first part of the sunflower to grow. It will grow downward because of the force of gravity. The roots will hold the sunflower in the ground. This is a big job because your sunflower may grow to be over seven feet tall! The roots will also help feed the plant so that it can grow to be so tall.
Most plants have similar external features such as leaves, stems and flowers. Certain external features of these parts can be similar or different. Plants can be grouped according to the external features. Plants which are similar in a certain external feature can be put in the same group. Plants can be also be grouped according to their similarities in other external features such as thorns and leaves.
