为什么植物会有种子？
1、种子是植物繁殖的一种方式，通过种子，植物可以在不依赖水的条件下传播和生长，提高了生存和扩散的效率。
2、种子内部含有胚胎和营养物质，可以为新植物提供生长所需的能量和养分，确保幼植物在恶劣环境中也能存活。
3、种子可以休眠，帮助植物应对不利环境，如干旱、寒冷等，等待适宜的时机再发芽生长，增加了植物的适应能力。
4、种子的外壳可以保护内部的胚胎和营养物质，防止被外界环境破坏或被其他生物吃掉，提高了繁殖成功率。
5、种子传播方式多样，如风力、水力、动物携带等，使得植物能够迅速占据更广泛的生存空间，避免了种内竞争。
总之，种子是植物适应环境、繁殖后代的重要机制，通过保护、休眠和传播等方式，提高了植物的生存和繁衍能力。
