Bean Seed Germination

Also called

Topics

• a seed has a seed coat, stored food in the cotyledons, and a tiny plant (embryo) with a radicle and a plumule
• a bean is a dicot: its seed has two cotyledons
• water, air (oxygen) and suitable warmth are needed for germination; soil and sunlight are not needed to start it
• the seed takes in water, swells a little and the seed coat splits
• the radicle comes out first and becomes the first root; side (lateral) roots branch from it later
• in a bean the shoot comes up as a hook, then straightens and lifts the cotyledons above the soil
• the young seedling lives on the food stored in its cotyledons, which shrink as the food is used
• once the first true leaves open, they make food using light
• a seed kept dry does not germinate, but it is not destroyed: it waits (stays dormant)
