苹果种子

苹果是一种常见的温带作物，其种子是成熟后在果肉中形成的。苹果种子通常呈圆形或椭圆形，有时甚至会显得有些扁平。这不仅是因为它们需要通过生长过程中的压力和重力影响来适应其所在环境，确保能够正确地分开并播下，但也反映了它们内在的生物学功能，即保证新生命的产生。每颗苹果种子都有一个坚硬的小壳保护着里面的胚芽，这个胚芽将发育成为新的植物。

苹果树需要经过多年的培育才能达到产花和授粉阶段，并最终结实为可食用的苹果。在这个过程中，它们依赖于无数小小的助手——蜜蜂等昆虫，帮助传递花粉，使得授精能够发生，从而开始繁殖新的生命体。这是一个复杂而微妙的过程，每一步都涉及到精细调节，以确保遗传信息能被准确地传递给下一代。

香蕉种子

bananas are a popular fruit that grows on large plants with thick, fleshy stems that act as pseudostems to support the plant's height and provide structural integrity. The seeds of bananas are not typically found in commercial varieties due to selective breeding for desirable traits such as sweetness, flavor, and texture.

However, wild bananas do contain many seeds per fruit. These seeds serve an important function by allowing the banana plant to reproduce naturally in its native habitat. Each seed is surrounded by a soft pulp which provides nutrients for the developing embryo during germination.

Orange citrus fruits like oranges and grapefruits have small black or brown seeds scattered throughout their pulp. These tiny structures may be easily overlooked when eating these fruits fresh or consuming them in juice form.
