Educational model of a bean plant growing roots, sprouting through the soil, and growing leaves. A great way to learn how plants sprout from seeds.
Our Green Bean Life Cycle Set Have you ever wondered how plants grow from seeds? Our green bean life cycle set depicts the germination process of a plant seed. It comes in a blister pack attached to a nine-inch tall card. The back of the card describes the four stages of seed development in English, French, and Spanish. The four plastic models can be removed from the card for closer study. They include: the bean (seed) under ground beginning to put forth a root (1 1/2 inch block), plant sprouting out of the ground and young root system (1 3/4 inches tall), first leaves breaking through the seed leaves (3 inches tall), and young bean plant with developing root system (4 inches tall). Our lifecycle set is made by Safari, Ltd., one of the best names in accurate and scientific animal replicas. Although this plastic plant is not an animal, Safari's vast experience makes it look almost real. Each stage of the life cycle is detailed with a large enough model that you can pass the models around the classroom or give them to your kids to study up close where they can learn in a very memorable, hands-on way about how seeds turn into plants. What a fun way to learn biology! You could even use these high-quality replicas as a museum display. See our other plant toys and gifts along with our series of life cycle biology models. Sprouting Green Bean Facts When you eat a green bean you are actually eating the unripened fruit of a strain of beans that have been developed over a long time to be good. That is true whether you are eating green beans, string beans, snap beans of the various French varieties such as French green beans or French beans which have been grown to be longer, thinner, and crisper than the other varieties. It is also true that regardless of the type, our life cycle model works to depict exactly what happens long before the unripened leftovers arrive at your table. Whether they are bush beans or pole beans (those are the ones that grown in vines on a support of some type), all 130 varieties of green beans start from seeds. First, the seed sits underground a couple of inches or more from the surface. When the conditions are right, the seed begins to put out a long root. That root is called a tap root and it is the main root. It will tend to go straight down, and various secondary roots will extend off from the main root. At the same time the beginnings of the plant will break through the surface of the ground reaching for the sky and sunlight. Over the next several days the first leaves break through and up past the seed or starter leaves.
