entoblast的音標是["ent??bl?st]，意思是“內胚芽細胞”。速記技巧可以考慮使用其發音的音節來幫助記憶，例如可以將字母e、n、t、o分別看作是音節的重音部分，而b、l、a、st則可以看作是音節的輕音部分。同時，也可以將單詞分解成更小的部分來記憶，例如可以將單詞分解成“en-to-b-la-st”，這樣也可以幫助記憶。

Entoblast這個詞源自希臘語，意為“植物原基細胞”。它的變化形式包括名詞形式如entoblasts，entoblastsemia，以及形容詞形式entoblastic。

相關單詞：

embryoblast：胚胎原基細胞，指的是胚胎發育初期形成的細胞。

organoblast：器官原基細胞，指的是器官形成前的原始細胞。

meroblastic：指混合細胞，即由兩種不同類型細胞組成的細胞。

protoplast：原生細胞，指的是一個生物體或組織中最基本的、未分化的前體細胞。

metamorphosis：變形，指的是生物體從一個階段轉變為另一個階段的過程，常常涉及到細胞的分化與分裂。

以上這些單詞都與細胞和生命體的發育過程有關，體現了生物學中多樣化和動態變化的特征。每個單詞都有其特定的含義和用法，為我們的生物學研究提供了豐富的語言資源。

英文小作文：

Entoblasts are crucial for the normal development of embryos, as they are the cells that will form the body of the fetus. During the early stages of development, the entoblast undergoes a series of complex changes that allow it to differentiate into different cell types and form the organs and tissues of the body. These changes are essential for the normal development of the fetus and ensure that it is born healthy and able to function normally.

Entoblasts are also important for understanding human reproduction and embryology, as they provide insights into how embryos develop and how abnormalities can arise during this process. Understanding these cells is crucial for developing new methods of assisted reproduction and for preventing and treating birth defects and genetic diseases.
