Cells: One or Many

Visual Guide to Unicellular and Multicellular Organisms Grade 6 Science Supporting Diagrams and Examples

Unicellular Organism Examples

Inside a Single Cell

One cell performs ALL life functions Cell membrane controls what enters and exits Nucleus contains genetic information Cytoplasm is where chemical reactions occur Organelles work like tiny organs

Multicellular Organism Examples

{"left":"Plants: Trees, flowers, grass - made of millions of specialized cells\nAnimals: Humans, cats, birds - different cell types for different jobs\nFungi: Mushrooms and molds - cells work together in networks","right":"Each cell type has a specific function\nCells must communicate and cooperate\nSpecialized cells cannot survive alone"}

Cell Function Challenge

Look at the organism examples Identify: Unicellular or Multicellular? Explain: How do the cells work? Compare: What are the advantages of each type?
