The building blocks of life
- Every living thing — from a blade of grass to a blue whale — is built from cells 细胞.
- They are tiny, but inside each one is a busy world of parts that keep it alive.
生命的构建块
- 每个活的东西——从一片草叶到一头蓝鲸——都由细胞(cells)构成。
- 它们很微小,但每一个内部都是一个让它活着的部件的繁忙世界。
Which part of the cell contains DNA and controls the cell? · 细胞的哪个部分含有 DNA 并控制细胞?
The nucleus holds DNA and controls the cell. · 细胞核持有 DNA 并控制细胞。
Which part releases energy by respiration? · 哪个部分通过呼吸作用释放能量?
Mitochondria are the site of aerobic respiration. · 线粒体是有氧呼吸的场所。
The cell membrane's main job is to: · 细胞膜的主要工作是:
The membrane controls movement in and out. · 膜控制进出的移动。
Parts of an animal cell
- Cell membrane 细胞膜: controls what enters and leaves.
- Cytoplasm 细胞质: jelly where reactions happen.
- Nucleus 细胞核: contains DNA and controls the cell.
- Mitochondria 线粒体: release energy by respiration.
An animal cell: membrane, cytoplasm, nucleus, mitochondria and ribosomes
一个动物细胞的部分
- 细胞膜(cell membrane):控制什么进入和离开。
- 细胞质(cytoplasm):反应发生的果冻。
- 细胞核(nucleus):含有 DNA 并控制细胞。
- 线粒体(mitochondria):通过呼吸作用释放能量。
一个动物细胞:膜、细胞质、细胞核、线粒体和核糖体
Explore the parts of a cell · 探索一个细胞的部分
Tap each part of the cell to see what it does. Some parts (cell wall, chloroplast, vacuole) are found only in plant cells. · 点击细胞的每个部分,看它做什么。一些部分(细胞壁、叶绿体、液泡)只在植物细胞中。
Which parts are found ONLY in plant cells? (Select all that apply.) · 哪些部分只在植物细胞中?(选择所有适用的。)
The nucleus is in both; the cell wall, chloroplasts and large vacuole are plant-only. · 细胞核在两者中;细胞壁、叶绿体和大液泡是植物专有的。
The plant cell part made of cellulose that gives support is the cell . · 由纤维素构成、给予支撑的植物细胞部分是细胞。
The cellulose cell wall supports and shapes plant cells. · 纤维素细胞壁支撑植物细胞并赋予其形状。
Extra parts in a plant cell
- Cell wall 细胞壁: made of cellulose 纤维素, gives support and shape.
- Chloroplasts 叶绿体: contain chlorophyll 叶绿素 for photosynthesis.
- Large vacuole 液泡: filled with cell sap, keeps the cell firm.

一个植物细胞中的额外部分
- 细胞壁(cell wall):由纤维素构成,给予支撑和形状。
- 叶绿体(chloroplasts):含有用于光合作用的叶绿素。
- 大液泡(large vacuole):充满细胞液,使细胞坚硬。

Animal vs plant cells
- Both have a membrane, cytoplasm, nucleus and mitochondria.
- Only plant cells have a cell wall, chloroplasts and a large permanent vacuole.
All plant cells have a cell wall, but not all have chloroplasts. Root cells, for example, are underground and get no light, so they have no chloroplasts. Don't assume every plant cell is green.
A plant cell also has a cell wall, a large vacuole and chloroplasts
动物对植物细胞
- 两者都有一个膜、细胞质、细胞核和线粒体。
- 只有植物细胞有一个细胞壁、叶绿体和一个大的永久液泡。
所有植物细胞都有一个细胞壁,但不是所有都有叶绿体。 例如,根细胞在地下且得不到光,所以它们没有叶绿体。不要假设每个植物细胞都是绿色的。
一个植物细胞还有一个细胞壁、一个大液泡和叶绿体
You've got it
- all cells have a membrane, cytoplasm, nucleus and mitochondria
- plant cells also have a cell wall, chloroplasts and a large vacuole
- the nucleus controls the cell; mitochondria release energy
你掌握了
- 所有细胞都有一个膜、细胞质、细胞核和线粒体
- 植物细胞还有一个细胞壁、叶绿体和一个大液泡
- 细胞核控制细胞;线粒体释放能量
