Life Cycle of a Plant

• How living things grow, live, and die

2nd grade Science
2
A plants 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 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.

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.
