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.
