The Life Cycle of a Plant
Today’s Learning Goal
• Earlier this week, you planted a Wisconsin Fast Plant!
Now you are eagerly waiting to observe its life cycle.
• To help you build background on the stages of a plant’s
growth, you will read some slides today, take notes from
them on the stages of a plant’s growth, draw some
diagrams, and possibly view some plant videos.
Your instructions
• Make a heading in your notebook for The Life Cycle of a Plant.
• Read each slide carefully.
• For each slide, write down
• The heading (like 1. Germination)
• Copy the information down for that part of the life cycle.
• When you are done with writing the notes, follow the directions on the other
slides.
The Life Cycle of a Plant
1. Germination
• The seed coat is softened by water.
• The seed splits open.
• The new plant inside (the embryo) begins to grow up.
• The root begins to grow down into the soil.
2. Sprout or Seedling
• A small shoot pushes up through the soil, beginning the plant’s
growth.
• The stem and “seed leaves” turn green as CHLOROPHYLL (a green
chemical) begins to form. Chlorophyll is one the things needed for a
plant to make its own food.
3. Plant Growth
• The stem grows thicker and stronger.
• The plant becomes green with CHLOROPHYLL inside it.
• It develops LEAVES, which are “food factories”. They make food for
the plant by the process of PHOTOSYNTHESIS.
• The plant grows taller.
4. Flower buds
• Flower buds begin to form at the tips of some stems.
• They are important beginnings of new flowers, from which new seeds
will form.
5. Flowers
• A flower opens its colorful petals up, with important parts in the
center to help to create a new seed.
6. Pollination
• An insect, bird or the wind has to help transfer pollen grains from the
plant of one flower to a flower of a different plant.
• The flower is then fertilized and a new seed begins to grow inside the
flower.
7. Fruit or seed pod formation
• A fruit or seed pod grows around the seed to protect the seed.
• The flower dies and the fruit or seed pod dries up and splits open,
releasing the seeds.
8. Seed dispersal
• The seeds fall out of the fruit or seed pod into the soil, or gets carried
to a new location by the wind, water or animals.
• Some seeds have hooks, burrs, or sticky surfaces to help them travel.
• Once they fall on new soil, the life cycle begins again, as the seed goes
into the ground and germinates.
Life Cycle in Pictures
• You will draw a series of diagrams/pictures in your notebook to show
the life cycle of a plant in pictures.
• Press “Escape” to get out of full-screen view of the presentation.
• Scroll back to 1. Germination.
• Write the heading for the slide, and draw a diagram based on one of
the illustrations on the slide. Do your best to draw it accurately! Add
color if you can!
If you are done….
• Go to www.kyrene.org
• Click Students, then Educational Resources,
then choose Discovery Education.
• Log in with your usual Kyrene number and password.
• Once you are in, type “Plants” in the
Search box at the top.
Put on headphones and watch some video clips
about plants!
