Biology B2 Cells

Basics

• The different parts of the cell are called organelle 
• The main types of cell you will be asked about are; animal cells and plant cells 
• They have many similar features, but plant cells have 3 individual features 

Animal Cells 

• Nucleus  - The nucleus controls the activities that occur within the cell 
• Cell Membrane - The cell membrane controls what substances pass into and out of the cell 
• Cytoplasm   - The cytoplasm is the jelly like substance where reactions occur
• Mitochondria/on - Energy is released from the mitochondrion during respiration 
• Ribosomes - This is where protein synthesis occurs 

• Nucleus  - The nucleus controls the activities that occur within the cell 
• Cell Membrane - The cell membrane controls what substances pass into and out of the cell 
• Cytoplasm   - The cytoplasm is the jelly like substance where reactions occur
• Mitochondria/on - Energy is released from the mitochondrion during respiration 
• Ribosomes - This is where protein synthesis occurs 
• Vacuole - This contains cell sap and helps give structure to the cell 
• Choloroplasts - Contain chlorophyll, a green pigment, which absorbs sunlight for photosynthesis 
• Cell Wall - Gives the cell structure 

Differences 

Organelle shared by animal and plant cells 

• Nucleus  - The nucleus controls the activities that occur within the cell 
• Cell Membrane - The cell membrane controls what substances pass into and out of the cell 
• Cytoplasm   - The cytoplasm is the jelly like substance where reactions occur
• Mitochondria/on - Energy is released from the mitochondrion during respiration 
• Ribosomes - This is where protein synthesis occurs 

Organelle individual to plant cells 

• Vacuole- This contains cell sap and helps give structure to the cell 

• Choloroplasts- Contain chlorophyll, a green pigment, which absorbs sunlight for photosynthesis 
• Cell Wall- Gives the cell structure
