Life Cycle of a Plant How living things grow, live, and die 2nd grade Science
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.
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
As the sprout continues to develop, it will grow roots, a stem, leaves, and flowers which will form more seeds At this stage, the life cycle of the plant begins again.
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.
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.
