Definition
Seed development refers to the process by which fertilized ovules mature into seeds, involving cellular differentiation and the accumulation of nutrients. Germination is the process by which a seed absorbs water, swells, and initiates growth, leading to the emergence of a new plant.
Summary
Seed development and germination are crucial processes in the life cycle of plants. Seeds form from fertilized ovules and contain all the necessary components for a new plant. Understanding the structure of seeds, including the seed coat, embryo, and endosperm, is essential for grasping how plants grow. Germination is the process that begins when a seed absorbs water, leading to the growth of roots and shoots under suitable environmental conditions. The success of germination and subsequent plant growth is influenced by various factors such as moisture, temperature, and light. Each plant species has specific requirements for germination, and understanding these can help in agriculture and gardening. By learning about seed development and germination, students can appreciate the complexity of plant life and the importance of plants in our ecosystem.
