Seedcase: Understanding the Protective Shell Around Seeds
Seedcase, also known as the seed coat, is the protective outer covering of a seed. It plays a crucial role in safeguarding the seed from damage, pathogens, and unfavorable environmental conditions. The seedcase is formed from the integuments of the ovule after fertilization, providing a barrier that helps ensure the survival and germination of the seed.
The Function of Seedcase
The primary function of the seedcase is to protect the seed from mechanical injury, pathogens, and desiccation. It acts as a barrier that shields the seed from external threats, such as pests and harsh weather conditions. Additionally, the seedcase regulates the exchange of gases and moisture, promoting proper seed development and germination.
Structure of Seedcase
The structure of the seedcase varies among different plant species. In general, the seedcase consists of two layers: the outer seed coat and the inner testa. The outer seed coat is often tough and impermeable, providing physical protection, while the testa may have specialized features like micropyles for water uptake during germination.
Importance of Seedcase
The seedcase is essential for seed dormancy and viability. It prevents premature germination and ensures that the seed remains viable until conditions are favorable for growth. Some seeds have hard seedcases that require scarification or stratification to break dormancy and initiate germination.
Seedcoat Adaptations
Seeds exhibit a wide range of adaptations in their seedcases to suit their dispersal and germination needs. Some seeds have wings or other appendages on the seed coat for wind dispersal, while others have fleshy seed coats that attract animals for seed dispersal. These adaptations enhance the survival and dispersal of seeds in diverse ecosystems.
Seedcase Examples

- Animals may help to spread seeds by eating the seedcase and depositing the seeds elsewhere.
- The seedcase of the dandelion can be carried far by the wind, aiding in seed dispersal.
