Embryo developing plant still inside the seed 5. seed leaf part of the seed that contains stored food used for initial growth 6. dicotyledonous (or idiotic for short) seed with two cotyledons Checking for understanding At the end of this section, film one of the following for a quick check ask the students to collaborationist share and think, pair and share, do a quick 3 excogitate 1 OFF down to check for understanding. Determine the level of ascendence for individually student and provide individual remediation as needed.Prep On the day before starting the experiment, soak dried lima beans in water. They will absorb some of the water and get a cushy outside cover ing (seed coat). Procedures/Activities examining a Bean Seed 1. Give each student a lima bean on a paper plate. Identify the seed coat. 2. Carefully rub the seed between your click and fingers. The seed coat will crack and slip off the seed easily. 3. Identify the cotyledon. This is the large oval part of the seed containing the food he seed needs before it can get nutrients from the soil and water. . The bean seed has a slit going down the middle of the seed. offend it open into 2 halves. Inside is a tiny plant called an embryo. A bean seed has two parts. Therefore, it is a Dicotyledonous, or idiotic for short. 5. find out the bean parts using a magnifying glass.
