花是被子植物. A Flower contains both male and female reproductive parts within it. Anthers produce pollen grains that carry male gametes while pistil bears female gametes. Pollens are transferred into the stigma of pistil by pollinators during the pollination. Once pollination occurs,合成或男女配子的受精。一些花表现出自施肥，而一些花则表现出交叉施肥。当交叉施肥不可行时，花随自施施用。裂缝和蓝斑花是两种主要的花类型。

什么是裂痕?

Chasmogamy is a mechanism of pollination and the flowers that show chasmogamy are chasmogamous flowers. Chasmogamous flowers are prominent, and they open their floral parts including anthers and stigma of pistils for the pollination.

裂痕flowers are bisexual and mostly show cross pollination. However, there is self pollinating chasmogamous flowers as well. Since cross pollination occurs, chasmogamous flowers require pollinators (abiotic or biotic pollinators). And also chasmogamous flowers produce seeds that are genetically distinct. Hence, these flowers increase the genetic diversity of the population, reduce theinbreeding depression, and retard the deleterious effects of recessive alleles.

什么是克利斯蒂安妈妈?

继续教育istogamy is another type of pollinating mechanism in which pollination and fertilization occur in unopened flowers or flower buds. Those flowers are known as cleistogamous flowers. They don’t open their reproductive parts to the out. They remain closed, and they force self pollination and fertilization. Hence, cleistogamous flowers do not need pollinators or attractive floral parts or nectaries to reward pollinators.

这些花在土壤中观察到，它们很小，不能以花为花。花生，豌豆和五月是丁香花的例子。

What are the Similarities Between Chasmogamous and Cleistogamous?

• 裂缝和蓝菌花属于被子植物。
• 裂缝和蓝果花都表现出自我施肥。
• 花卉of Chasmogamous and Cleistogamous are bisexual.
• 授粉和施肥都发生在裂缝和颈椎花朵中。

裂痕和克氏菌之间有什么区别？

chas虫与蓝菌
裂开的花朵是将其生殖零件暴露于授粉中的花朵。	丁香的花朵是不打开的花朵，并阻止它们暴露于生殖部位并迫使自施肥。
Nature
裂痕flowers are opened.	蓝花朵保持关闭。
受精
裂痕flowers show both self and cross fertilization.	乳木果总是表现出自我施肥。
生物和非生物传粉者的责任人
裂痕花由生物或非生物传粉媒介授粉。	Pollinators are not involved with Cleistogamous flowers.
Exposing Anthers and Stigma
裂开的花朵暴露了花药和污名。	克利斯蒂安妈妈flowers never expose anthers and stigma.
授粉和施肥
开花后，裂缝花的授粉和受精。	Pollination and fertilization of cleistogamous flowers occur while during the closed state.
花卉
裂痕flowers are prominent.	克利斯蒂安妈妈flowers are not much distinguishable.
ATTractive Floral Parts
裂痕flowers posses attractive floral parts to attract pollinators.	克利斯蒂安妈妈flowers do not possess attractive floral parts.
Coloured Petals
裂开的花经常有彩色花瓣。	蓝果花不具有色花瓣。
Nectaries
裂开的花朵有蜜化。	克利斯蒂安妈妈flowers do not have nectaries.
Pollen Production
裂痕flowers need to produce a large amount of pollen.	克利斯蒂安妈妈flowers do not need to produce a large amount of pollen.
植物资源生产种子的要求
Chasmogamy needs comparatively higher plant resources for seed production.	克利斯托妈妈需要较少的植物资源来生产种子。
Advantages
裂痕flowers produce seeds that are genetically distinct hence, it increases genetic diversity, reduce inbreeding depression and deleterious effects of recessive alleles.	乳木糖不需要传粉媒介进行授粉。而且还需要更少的植物资源来生产种子。
缺点
裂痕flowers need pollinators. Hence, they depend on pollinators.	克利斯蒂安妈妈flowers produce seeds that are genetically similar. Hence, increases the inbreeding depression and deleterious effects of recessive alleles.

摘要 - 裂缝vs克利斯蒂安妈妈

裂痕flowers perform pollination and fertilization after opening their floral parts. Both cross and self pollination occur in chasmogamous flowers, but cross pollination is most common and favoured. Cleistogamous flowers carry out pollination and fertilization before opening or inside the flower bud. However, they do not expose floral parts specially anthers and stigma. Hence, they always encourage the self pollination. This is the difference between chasmogamous and cleistogamous flowers.
