Plant life cycles Okay, okay…..so you think you know everything about how a plant grows. Well, this is a review….and you need to learn the proper words about the plant cycle. Can you do that?
Plant life cycles Important: You MUST read every slide!!!!!
Plant life cycles The good news is that this will be fun. I know…..you’re bored already. But, as usual, I found some interesting links you can enjoy. The important thing is that you MUST learn a few words. I will put these words on the next screen. THEN I will explain each word to you. At the end, you will need to remember the words so that you can finish your paperwork. Not so hard if you put your mind to it. Or you can pout, fall over, and cry like the rain……… That’s okay, Rain makes plants grow, and we can use more plants in the world!
Plant life cycles Words you will learn: Seed dispersion Life cycle Leaves Stem Roots Seeds Seed Coat Pollen/Pollinate Flowers
First word: Life Cycle The life cycle of a human is that he (or she) is born, is a baby, grows into a child, turns into a teenager, drives a car, gets a job, and becomes an adult. When he meets someone, he might have another child. Then he will eventually grow old and die. HIS child will then be grown and have another child. That is a cycle, and that is the cycle of a human life.
Second word: Plant Life Cycle Yeah, this part you know. A plant has the same cycle of life as humans, although they aren’t smart or as creative as humans are. Nor are they able to walk around and draw on the walls. BUT, the cycle of life is the same. It goes around like a circle.
Second word: Plant Life Cycle Look, young grasshopper, and you will see.
Third word: Seeds Well, of course SEEDS are important! I can hear you say.....……but why? What are they really? What is inside a seed? What makes a seed turn into a plant?
Third word: Seeds A seed holds a lot of information inside it’s tiny brown ball. This information tells the seed what sort of plant it will become, if it will have blue or red flowers, if it will make fruit we can eat, or fruit that is poisonous. How does this little round ball grow? We know that a seed needs three things: LIGHT, WATER, and SOIL. Why?
Fourth word: Seed Coat Inside the seed is a tiny new plant. The outside of the seed has a special covering called a seed coat. 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.
Fifth word: Roots When the seed gets the right amount of water, warmth, and air, it can begin to grow. What would happen if a seed had LIGHT but no WATER? Click on this link, and let’s find out: http://www2.bgfl.org/bgfl2/custom/resources_ftp/client_ftp/ks2/science/plants_pt2/light.htm

Sixth word: Leaves But what happens when everything is perfect? There is LIGHT, WATER and good SOIL? Click on this link and find out: http://www2.bgfl.org/bgfl2/custom/resources_ftp/client_ftp/ks2/science/plants_pt2/light_water.htm
Seventh word: Stem 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. 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.
Eighth word: 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.
Ninth word: Flowers Flowers are brightly colored for a reason. Butterflies and other flying insects like bees think they are beautiful if they are colorful. This is called: attraction. A flower wants to have the best perfume and color, so it can have the most insect and human visitors in all of the garden.
Tenth word: Pollen The flower will have pollen (usually yellow or orange powdery substance inside the flower itself). This pollen is delicious for bees and other insects to use for food. When they go from plant to plant, they pollinate other plants. This helps reproduce more plants, by telling the plant that it is now time to stop feeding the flower, and instead make a new seed. Seeds ONLY come after being pollinated.
Tenth word: Pollen Lots of insects, animals and even people transfer pollen from one plant to another. Bees, butterflies, hummingbirds, or animals in passing. This is an important part of our ecosystem. Even YOU have transferred pollen from one plant to another!
Eleventh word: Seed Dispersal For a plant to reproduce, it MUST spread it’s seeds far away. This is because there is not enough soil for all the seeds to grow where they are grown. How is this problem solved? Click on this link to see how seeds are spread, and plants can then reproduce. This is called SEED DISPERSAL. http://www2.bgfl.org/bgfl2/custom/resources_ftp/client_ftp/ks2/science/plants_pt2/dispersal.htm
Plant life cycles So…..you lived. You remembered how a seed turns into a plant, and you were able to enjoy a few interesting links. Now, you need to review, in order to understand the words we studied this week about a plant’s life cycle.
Plant life cycles Words you have learned: Life cycle ………………….........…how things grow and reproduce Leaves...parts of the plant that absorb heat from the sun, and make food for the plant Stem……………….part of the plant that holds it tall and helps it stand strong Roots…….holds the plant in the ground. It is the first part of the seed to grow, and pulls nutrients (food) from the soil for the sprout to grow. Seeds….the part of a plant that follows a pollinated flower in order to reproduce and cause a new plant to grow. Seed Coat….the hard shell that protects the seed from the weather and being stepped on or blown in the wind. Pollen….a powdery substance inside a flower that attracts bees and other insects, and helps the plant to pollinate, and to then form seeds. Flowers….makes brightly colored pollen for bees and other insects to come and collect.
