发现花在植物中的功能是什么

所有的植物都是地球的根本。 它们负责提供呼吸的新鲜空气,维持环境和生态平衡,滋养土壤,生产食物,以及点缀它们所种植的所有空间。 但是,你有没有停下来思考过 花的功能是什么 ?

它们色彩鲜艳,性格开朗,能够使任何环境变得更加美丽。 然而,许多人不知道它们的真正功能是什么。

这朵花的功能是什么?

在全世界已知的大约35万种植物中,25万种是被子植物,是植物界中种类最多的一组。

被子植物是产生花朵的植物。 这种富有同情心和色彩的结构有一个主要功能: 进行有性繁殖 通过这种方式,有可能使生态系统始终保持更新。

被子植物如何繁殖

许多植物是单性的,即它们有一个雄性(雄蕊)或雌性(雌蕊)的生殖器。

在雄性器官中,配子(花粉粒)的产生是在花药中完成的,而在雌性器官中,它是在心皮中产生的。

然后,为了实现受精,两种配子必须相遇,形成子宫,即新生物体的第一个细胞。 第一次分裂后,它被称为胚胎。

回放遵循这些步骤:

  1. 花药产生花粉
  2. 它被授粉,直到到达位于雌性器官上的柱头。 从那里,开始发芽
  3. 卵粒从花柱下降到卵巢,直到最后与卵子相遇,受精过程实际发生在这里。

必须指出的是 大多数花不接受其他物种的花粉 因此,不同的物种之间不会发生受精作用。

除了单性的,还有 雌雄同体的被子植物 换句话说,它们既有安体,也有妇科,就像橘子树一样。 在这种情况下,花本身没有性别,但有负责受精的女性和男性结构。

然后植物产生花粉,自己受精。

被子植物的果实是什么?

现在你知道了花的功能是什么,有必要强调另一个有趣的特点: 有些果实也是在子房内受精生长的 .

在这种情况下,子房变成了果实,而胚珠变成了种子。

被子植物的一些水果类型有:葡萄、黑莓、菠萝、李子和苹果。

授粉剂

植物的受精作用只有在以下因素的帮助下才能发生 授粉剂 虫子:昆虫,如蜜蜂和蝴蝶,鸟类,如蜂鸟和蝙蝠,甲虫和其他动物,以及风本身。

花朵有彩色的花瓣和吸引昆虫的气味。 所以授粉是成功的。

此外,花还为授粉者提供食物、住所、寻找伙伴的地方和其他好处。

就水果而言,动物因其营养储备而被吸引。 最有趣的是,种子有一层保护膜,使其无法消化。

因此,当它们被食用时,它们会随动物的粪便排出,这有助于种子在自然界传播。
