• Tissues


  • Groups of similar cells that work together to carry out a particular function
• Tissues


  • Muscle
  • Nervous
  • Epithelial

• Organ Systems


  • Digestive System
  • Circulatory System
• Organ systems work together to make entire organisms
• Enzymes are biological catalysts that speed up chemical reactions
• Enzymes


  • They are specific to the reactions they catalyse
  • They can be denatured by high temperatures
  • They are not used up in the reactions they catalyse
• Enzymes


  • Salivary enzymes
  • Digestive enzymes
• Tissues can be soft and quilted
