用法要点

句型搭配

通常作为名词使用,在句子中作主语、宾语或定语,常见于描述细胞结构和功能的句子中。

• The cytoplasm contains various organelles.
• Cytoplasm is essential for cellular metabolism.
• Cytoplasm in plant cells differs from animal cells.

介词用法

常与介词'in'连用表示位置,如'in the cytoplasm';也可与'of'连用表示所属关系,如'cytoplasm of the cell'。

• Organelles are suspended in the cytoplasm.
• The cytoplasm of eukaryotic cells is complex.
• Proteins move through the cytoplasm.

语域说明

主要用于生物学、医学等学术领域,在非专业日常对话中较少使用,属于正式或技术性词汇。

• In biology class, we studied cytoplasm.
• The doctor explained cytoplasm's role in health.
• Cytoplasm is a key term in cell biology.

基础例句

In science class, we learned that cytoplasm is the jelly-like substance inside cells.

在科学课上,我们学到细胞质是细胞内部的胶状物质。

The teacher showed us a diagram of a cell with cytoplasm highlighted in blue.

老师给我们看了一张细胞图,其中细胞质用蓝色突出显示。

I remember that cytoplasm contains important parts like mitochondria and ribosomes.

我记得细胞质包含线粒体和核糖体等重要部分。

When studying biology, understanding cytoplasm helps explain how cells work.

学习生物学时,理解细胞质有助于解释细胞如何运作。

高级例句

Recent research indicates that cytoplasmic streaming plays a crucial role in nutrient distribution within plant cells.

最近的研究表明,细胞质流动在植物细胞内的养分分配中起着关键作用。

In eukaryotic cells, the cytoplasm is compartmentalized to facilitate specialized metabolic processes.

在真核细胞中,细胞质被分隔以促进专门的代谢过程。

The pharmaceutical company is developing drugs that target cytoplasmic enzymes to treat metabolic disorders.

这家制药公司正在开发针对细胞质酶以治疗代谢紊乱的药物。

During cell division, the cytoplasm divides through a process called cytokinesis, ensuring genetic material is evenly distributed.

在细胞分裂过程中,细胞质通过胞质分裂过程进行分裂,确保遗传物质均匀分布。

常见错误

❌ 错误:The cytoplasm is the same as the cell membrane.
✓ 正确:The cytoplasm is inside the cell membrane, not the same as it.

错误地将细胞质等同于细胞膜。细胞质位于细胞膜内部,是细胞内的物质,而细胞膜是包围细胞的边界结构。应区分两者,细胞质是内部内容,细胞膜是外部屏障。

❌ 错误:Cytoplasm only exists in animal cells.
✓ 正确:Cytoplasm exists in both animal and plant cells.

错误地认为细胞质仅存在于动物细胞中。实际上,细胞质是所有类型细胞(包括植物、动物、真菌等)的基本组成部分,是细胞内的通用结构。应更正为细胞质普遍存在于各种细胞中。

近义词辨析

protoplasm

原生质是一个更广泛的术语,指细胞内的所有活物质,包括细胞质和细胞核;而细胞质特指细胞膜内除细胞核外的部分。细胞质是原生质的一部分。

Protoplasm includes both cytoplasm and nucleus, whereas cytoplasm excludes the nucleus.

cytosol

细胞溶胶是细胞质的液体成分,不包括细胞器;而细胞质包括细胞溶胶和悬浮在其中的所有细胞器。细胞溶胶是细胞质的一个子集。

Cytosol is the fluid part of the cytoplasm, while cytoplasm encompasses cytosol plus organelles like mitochondria.
