Life Cycle of a Plantby Kaitlyn Lanham

Grade Level and Expectations

• 1st grade Life Science

• Students will be able to determine the order of a life cycle.

• Students will comprehend the influences of seasons, weather, and animal life on the development of a seed.

• These will be determined by a quiz that will consist of three multiple choice questions.

Where did the seed come from?

• Before a plant grows, a seed hast to be planted. There are a few helpers with this:

• Birds

• Weather

• The plant

Go back to quiz.

Birds help plant seeds by eating berries, nuts, and some flowers. The seeds are processed and dropped by the birds far away from where the seed first started.

There is an animal that helps plant nut trees. It is small and furry, sometimes brown, and can make a chattering sound.

What is it?

The weather helps plant seeds by gentle or fierce winds blowing them from their parent plant to soft ground. Some like dandelion seeds are designed for the wind to pick them up and whisk them off.

The plant itself helps with replanting the seeds by dropping them into the ground.

How does the seed become a plant?

• This process is called germination.

• Germination takes place in spring time when the sun is shining and there is just enough water.

• The water and warmth from the sun wake the seed up, causing it to grow roots.

Water Sun = Happy Seed+

The seed is now ready to become a plant.

Germination

• Once the germination process has started the cotyledon splits open and the roots start to emerge, reaching into the dirt for food and water.

Cotyledon: the tough coat that protects the seed before it is planted.

Information from

• The shoot, stem and leaves, will start to grow up through the soil toward the warmth of the sun. The next stage is as a seedling.

Stages of germination

Watch this to see the process of germination.

Seedling

• When the roots grow down into the soil and the stem and leaves grown up toward the sun the seedling stage has started.

• During this stage the plant will get its food from the sun, through a process called photosynthesis; water and other nutrients will be brought to the plant by its roots.

Light is absorbed by the chlorophyll in the leaves and turned into food for the plant.

Chlorophyll is what makes the leaves green.

Mature Plant

• The plant will now produce flowers which will become fruit with more seeds inside.

• Once summer is past and fall comes around the fruit will release the seeds.

• This is the life cycle of a plant.

Let’s review!

• Weather, birds, and plants are helpers in the process of planting seeds.

• When there is the right amount of water and sun the seed starts to germinate.

• The next stage is as a seedling, small leaves grow on shoots of the plant.

• After growing for a while the plant will mature, flowers will blossom containing seeds to start the process over again.
