1 How living things grow, live, and die Life Cycle of a PlantHow living things grow, live, and die2nd grade Science
2 A plant’s life cycle starts with a seed. Inside the seed is a tiny new plant.The outside of the seed has a special covering called a seed coat.
3 When the seed gets the right amount of water, warmth, and air, it can begin to grow. If conditions remain just right, after a time the little seed will sprout.The sprout will grow to look like the plant it came from
4 As the sprout continues to develop, it will grow roots, a stem, leaves, and flowers which will form more seedsAt this stage, the life cycle of the plant begins again.
5 It Starts With a Seed.From a seed, a small root grows down into the soil.Then, the stem grows up toward the surface of the soil.Soon, the stem breaks through the soil. When this happens, it is called a sprout.
6 The Cycle Continues Later, leaves begin to form on the plant stem. Now it is called a seedling and can make its own food.Finally, the seedling develops into a plant which will look like the plant it came from.
