Life Cycle of Plants Study Guide Vocabulary ● Many plants grow from seeds. ● The plant parts that grow out of stems are leaves. ● All plant parts are made of cells. ● Chlorophyll gives plants their green color. ● A seed needs water to germinate. ● A young plant is a seedling. ● The underground parts of a plant is a plant that take in water and nutrients from the soil are the roots. ● The food-making process of plants is photosynthesis. ● A stem connects the roots and leaves of a plant. ● A plant with no roots, stems, or leaves is a simple plant. Parts of a Flower Important Concepts How Plants Grow What Plants Need What Seeds Do How Plants Make Food Roots helps a plant take in water and nutrients from the soil. Many Plants can form seeds. Seeds need air, and water to sprout. Seeds are spread in many ways. Plants make their own food by a process called photosynthesis. Leaves take in carbon dioxide from the air. They give off oxygen. Three ways seeds are spread are by wind, Chlorophyll in plants helps take in light. water, and animals. Parts of a Seed (embryo) Plant Video From “You Tube” http://www.neok12.com/php/watch.php?v=zX447672777b04515b18737f&t=Plants Photosynthesis Video http://www.neok12.com/php/watch.php?v=zX4b7a504d047d5b6e660173&t=Plants Seedling Lapse Video http://www.neok12.com/php/watch.php?v=zX000e665066767b7b72457b&t=Plant s Critical Thinking If there were little or no rain for a long period of time, a farmer’s crop would… The plants would die from the lack of water unless the farmer provided water to the plants from another source. How can a dandelion growing in the schoolyard be a parent to young dandelion plants growing miles from school? Wind can carry seeds from the dandelion great distances. The seeds may be dropped in a new location miles away and grow into new plants. If a plant reproduces by bulbs, does it make seeds, too? Explain. Plants that make bulbs also make seeds. It is easier to produce new seeds from the bulbs. Process Skills Review You are growing two plants. You want to test one plant to find out how sunlight affects its growth. You will provide the other plant with everything it needs for growth. Explain how you will observe the plants and compare your results. One plant will be provided with water, air and soil, but not sunlight. The other plant will be provided with air, water, soil and sunlight. I will observe both plants and record what happens to them. This allows me to compare the plants to learn what the role of sunlight is in plant growth. What can observing tree leaves help you learn? Observing different traits of the leaves such as size and shape can help you identify the type of tree the leaves came from.
