What we are studying and why? Today we are going to be studying the life cycle of a plant. Plants are a vital part of our every day lives. They provide nutrients, herbs, food and much more. It is important we realize plants are constantly changing and that we are able to identify those changes. Teachers
Seed Dispersal There are many kinds of seeds and each grow a different kind of plant, but where do seedscome from? Menu
Seed Dispersal The fruit of a plant grows during the spring and summer, like this apple tree shows. The seeds grow in the fruit of the plant. Menu
Seed Dispersal Plants become dormant during the fall and winter months. There are a number of ways that the seeds can leave the plant. Menu
Dormant When a plant is dormant it is during the fall and winter months. At this time the plant is not dead, just slowly growing.
Seed Dispersal Windcan blow the seeds and spread them around. Menu
Seed Dispersal Seeds in a pod can also burstopen and be spread around in this way. Menu
Seed Dispersal Plants can also shakeseeds off the plant. Menu
Seed Dispersal Watercan carry the seeds to different areas. Menu
Seed Dispersal Seeds can be carried away if they get caught on something. Menu
Seed Dispersal Animalseat seeds and they can be dispersedin that way. Menu
Seed Dispersal Sometimes seeds can justfall and rollaway. Menu
Seed Dispersal There are many ways seeds can be dispersed, but no matter which way they leave the plant they will eventually begin growingin the ground. End of section Click on menu Menu
Seed Growth Now that we have learned how seeds are dispersed, it is time we discover how seeds grow into plants! Menu
Seed Growth First seeds are planted in the ground. Menu
Seed Growth Roots begin to grow helping the seeds get nutrients. A shoot (a small stem) starts to grow out of the seed and up towards the ground. Menu
Seed Growth When the shoot reaches the surface of the soil, it becomes a sprout. Menu
Seed Growth Water, air, sunlight and nutrients from the soil help the sprout grow and turn into a seedling. Menu
Seedling A seedling is a small plant with very few leaves.
Seed Growth The seedling is now a young plant and plant growth is now noticeable. Menu
Seed Growth Do you know the order of seed growth? If you are unsure, review this part of the lesson again. End of section Click on menu Menu
Plant Parts It is important that we can identify the parts of plants so we know how the plant grows and what the parts do. Menu
Plant Parts • Seed • Roots • Stem • Leaf • Flower • Shoot • Fruit Menu
Plant Parts Can you identify all parts of the plant? End of section Click on menu Menu
Plant Growth As a young plant grows into an adult it grows more leaves and becomes a healthierand larger plant. Menu
Plant Growth However, if plants do not receive proper care or have to live in unfit conditions they will notgrow as well. Plant Growth Menu
Plant Growth Next, the plant will grow flowers or bloomswhich will then eventually grow fruit. Menu
Plant Growth The fruit grows during the spring and summer months, and when ripened can be harvested by humans or animals. Menu
Plant Growth As we have already mentioned before, the fruit contains the seeds and when the fruit has been produced the seeds can begin to be dispersed. Menu
Plant Growth Once the seeds are dispersed, the plant begins to become dormant. This is the last stage in the life cycle. When spring comes, dormancy will end and thelife cycle willbegin again. Menu
Plant Growth See a corn plant grow by watching this video! Menu
Plant Growth If you have questions about the plant life cycle, try going through parts of the lesson again or ask your teacher. If you know the material, you can move on to the review. Keep upthe good work! End of section Click on menu Menu

Quiz Good try but take another shot.
Quiz Something is always happening in the plant life cycle, try again.
Quiz Correct! A plant life cycle never stops, the plant just grows at a slower rate when dormant and begins growing faster whenspring begins.
Quiz 2) What does a plant need in order to grow? A) Water B) Air C) Sunlight D) Soil E) All of the above Menu
Quiz Close, but try again.
Quiz Air is very important but something else is needed too.
Quiz Nice try but it is not the right answer.
Quiz Soil provides nutrients but it is not the correct answer.
Quiz Good work! All of these are needed to make a plant grow.
Quiz 3) Where do seeds come from? A) The ground B) The plants fruit C) The store D) None of these Menu
