Both need air: animals breathe/respire oxygen plants use carbon dioxide in photosynthesis and give-off oxygen in that process.Both need water to develop and grow: animals drink water through their mouths plants intake water through their roots.Plants and animals have similar needs to grow.It should be planted is a pot with soil or in the ground. Once the seedling has leaves, it can begin to manufacture its own food via photosynthesis. Hypocotyl - emerges upward to become the base of the plant stemĮpicotyl - emerges above the cotyledons, which are used up by the embryo and become paper thin Bean Plant Germination:Īs the seedling starts to grow more parts are visible (on the Bean Plant Germination Diagram) At home you want to open the Bean Grow House to provide air and keep the seed moist. As the leaves emerge, however, the plant needs sunlight in order to conduct photosynthesis and survive. To germinate, seeds need warmth, not sunshine. The food for the emerging plant is stored inside the seed until the leaves emerge. The water will be absorbed by the seed, causing it to swell and the seed coat to soften. Keep your seed moist, but not soaking wet. Plants need sunlight (or artificial sunlight), water, nutrients, air, space, and support to grow, which you will provide when you transplant your seedling into a pot with potting soil. Under good conditions, beans germinate in eight to 10 days. Seeds need moisture, warmth and a small amount of oxygen to germinate, or begin to grow, which you will provide as you create the Bean Greenhouse. Place dampened cotton ball and 2 bean seeds in the small bag.An example of a monocot seed is a c corn seed. Therefore, a monocot seed has only one cotyledon and a dicot seen such as a bean has two cotyledons. If we break the words down, we see that "Mono" = one and "Di"=two and the "cot" is short for cotyledons. Most seeds can be classified into two groups. The beans will have similar structures, but they might look different Compare a dry bean with the bean you soaked.
Use a magnifying glass to see all the details of the bean. You may need to use the knife to cut through the bean coat. Split the softened bean in half, there is a line that runs down the middle of the seed coat.Hypothesize what the bean will look like on the inside before you cut it open.Today you are going to explore the parts of a seed and make a bean green house to germinate a seed and watch it grow. Local office information can be found on the 4-H county listing Let's Learn: To enroll your child in a 4-H club or to find out more about these curriculums for school enrichment or after school programs, contact the 4-H Educator at your local Extension Office.
Our 4-H Meet the Plants Project also guides youth to discover more about plant science as well and is a popular 4-H School Enrichment program for students in grades 2 through 5. This curriculum supports the National Science Standard (NS.K-4.1) Science as Inquiry. This Inspire Kids to Do Home Activity is adapted from Hot House Detective, 4-H Acres of Adventure Book 1, a National 4-H Curriculum. Youth will also learn about the requirements for seed germination (sprouting) while creating a mini greenhouse. This lesson provides youth with an opportunity to identify the parts of a seed and their functions. Have you ever wondered how a plant actually grows from a seed? Seeds actually have parts which support the plant as it begins to grow. Meet the Plants and Acres of Adventure Introduction: A pot and soil at a later date to transplant your seedĤ-H Project that aligns with this activity:.You will want to let the dried bean soak for 12- 24 hours Softened Lima Bean or large dried bean for dissection.Bean Seeds - (another medium to large seed could be substituted).*Elementary Suggested amount of time for lesson:ģ0 minutes to do the initial lesson, additional time to monitor the seed growth and development Supplies Needed
