Vegetable seeds are the small, often hard structures that can grow into new plants. They contain the genetic material needed for the plant's development and are essential for growing a variety of vegetables, such as carrots, tomatoes, and lettuce. Each type of seed has specific requirements for germination, including moisture, temperature, and light. These seeds can be purchased from garden centers or saved from mature vegetables. When planted in soil, they absorb water and nutrients, eventually sprouting into seedlings. Proper care, including watering and sunlight, helps ensure healthy growth and a successful harvest of fresh vegetables.
