📚 Year 8 WJEC Biology: Vocabulary & Terminology Quick-Memorisation Guide | Year 8 WJEC 生物：词汇术语速记指南

Mastering the key vocabulary in Year 8 Biology is the first step towards understanding complex life processes. This guide breaks down essential terms and provides memorable tricks to help you retain them for your WJEC assessments and beyond.

掌握八年级生物的关键词汇是理解复杂生命过程的第一步。本指南分解关键术语，并提供朗朗上口的记忆技巧，帮助你在WJEC考试及今后的学习中牢固掌握它们。

1. The Building Blocks of Life: Cells | 生命的基石：细胞

All living organisms are made up of cells, the smallest functional units of life. Animal and plant cells share some structures but have distinct differences that you must remember.

所有生物都由细胞构成，细胞是生命最小的功能单位。动物细胞和植物细胞共有一些结构，但存在明显差异，需要牢记。

Nucleus: The control centre of the cell, containing genetic material (DNA) that directs all activities. Think of it as the 'brain' of the cell.

细胞核：细胞的控制中心，含有指导一切活动的遗传物质（DNA）。将其想象成细胞的 '大脑'。

Cytoplasm: A jelly-like substance where most chemical reactions occur. It fills the cell and holds organelles in place.

细胞质：一种果冻状物质，大多数化学反应在此发生。它填充细胞并固定细胞器。

Cell membrane: A thin, flexible barrier that surrounds the cell and controls what enters and leaves. Remember 'membrane' means 'border guard'.

细胞膜：围绕细胞的薄而柔韧的屏障，控制物质进出。记住 '膜' 就像 '边境守卫'。

Mitochondria: Tiny rod-shaped organelles where aerobic respiration takes place, releasing energy for the cell. The mnemonic 'Mighty Mitochondria' can help you recall their role as the powerhouse.

线粒体：微小的棒状细胞器，是有氧呼吸发生的场所，为细胞释放能量。用 '强大的线粒体' 这个口诀来记住它是能量工厂。

Cell wall: A rigid outer layer made of cellulose found only in plant cells, providing structural support. Unlike the cell membrane, it is fully permeable.

细胞壁：仅存在于植物细胞中的由纤维素组成的坚硬外层，提供结构支撑。与细胞膜不同，它是全透性的。

Chloroplasts reen organelles containing chlorophyll that capture light energy for photosynthesis. Think 'chloro' = green, 'plast' = small body.

叶绿体：含有叶绿素的绿色细胞器，捕获光能进行光合作用。联想 '叶绿' 指绿色，'体' 指小体。

Permanent vacuole: A large, fluid-filled sac in plant cells that stores cell sap and helps maintain turgor pressure. In animal cells, vacuoles are small and temporary.

永久液泡：植物细胞中的一个大液囊，储存细胞液，帮助维持膨压。动物细胞中的液泡小而临时。
