Dena is cutting up a tomato. She looks closely at the seeds inside, and wonders if it comes from a flowering plant. Explain how you know the tomato comes from a flowering plant, and describe the stages in the life cycle of the tomato.
The tomato comes from a flowering plant because it has seeds. First, the tomato seed germinates, with the seeds absorbing water and the seed coat splitting open. Then, the plant uses the food inside the seed to grow, and the roots grow down into the soil. Leaves begin to make food for the plant, and the stem and leaves begin to grow. The plant grows into an adult plant and flowers begin to grow. The flower makes egg cells and pollen, pollination happens, and the fertilized eggs develop into seeds. Fruit forms around the seeds, the fruit and seeds separate from the plant, and the seeds germinate, beginning the cycle again.
