Study Notes
Diversity Of Living Organisms
- Living organisms can be classified into different categories based on their characteristics:
- Kingdom Monera (bacteria and blue-green algae)
- Kingdom Protista (protozoa and algae)
- Kingdom Fungi (mushrooms and moulds)
- Kingdom Plantae (plants)
- Kingdom Animalia (animals)
- Diversity of living organisms can be seen in:
- Different shapes and sizes
- Different modes of nutrition (autotrophic and heterotrophic)
- Different habitats (terrestrial, aquatic, and aerial)
Characteristics Of Living Things
- All living organisms exhibit the following characteristics:
- Nutrition: Living organisms need food for energy and growth
- Respiration: Living organisms breathe in oxygen and release carbon dioxide
- Movement: Living organisms exhibit movement, either internal or external
- Growth and Development: Living organisms grow and develop over time
- Reproduction: Living organisms produce offspring
- Sensitivity: Living organisms respond to stimuli
- Excretion: Living organisms remove waste products
Levels Of Organization
- Living organisms can be organized into different levels:
- Cell: The basic structural and functional unit of life
- Tissue: A group of similar cells performing a specific function
- Organ: A group of different tissues working together to perform a specific function
- Organ System: A group of organs working together to perform a specific function
- Organism: A living individual made up of different organ systems
Cell Structure
- A cell consists of:
- Cell Membrane: A thin layer that separates the cell from its environment
- Cytoplasm: A jelly-like substance inside the cell membrane
- Nucleus: The control center of the cell where DNA is stored
- Mitochondria: The powerhouses of the cell responsible for energy production
- Cell Wall: A rigid layer outside the cell membrane in plant cells
Basic Biological Needs
- Living organisms require:
- Food: For energy and growth
- Water: For various cellular activities
- Oxygen: For respiration
- Shelter: For protection from the environment
- Air: For respiration

Diversity Of Living Organisms
- Living organisms can be classified into five kingdoms: Monera, Protista, Fungi, Plantae, and Animalia
- Kingdom Monera includes bacteria and blue-green algae
- Kingdom Protista includes protozoa and algae
- Kingdom Fungi includes mushrooms and moulds
- Kingdom Plantae includes plants
- Kingdom Animalia includes animals
- Diversity of living organisms is seen in different shapes and sizes, modes of nutrition, and habitats
Characteristics Of Living Things
- Living organisms exhibit seven characteristics: Nutrition, Respiration, Movement, Growth and Development, Reproduction, Sensitivity, and Excretion
- Nutrition: Living organisms need food for energy and growth
- Respiration: Living organisms breathe in oxygen and release carbon dioxide
- Movement: Living organisms exhibit movement, either internal or external
- Growth and Development: Living organisms grow and develop over time
- Reproduction: Living organisms produce offspring
- Sensitivity: Living organisms respond to stimuli
- Excretion: Living organisms remove waste products
Levels Of Organization
- Living organisms can be organized into five levels: Cell, Tissue, Organ, Organ System, and Organism
- Cell: The basic structural and functional unit of life
- Tissue: A group of similar cells performing a specific function
- Organ: A group of different tissues working together to perform a specific function
- Organ System: A group of organs working together to perform a specific function
- Organism: A living individual made up of different organ systems
Cell Structure
- A cell consists of: Cell Membrane, Cytoplasm, Nucleus, Mitochondria, and Cell Wall (in plant cells)
- Cell Membrane: A thin layer that separates the cell from its environment
- Cytoplasm: A jelly-like substance inside the cell membrane
- Nucleus: The control center of the cell where DNA is stored
- Mitochondria: The powerhouses of the cell responsible for energy production
- Cell Wall: A rigid layer outside the cell membrane in plant cells
Basic Biological Needs
- Living organisms require five basic needs: Food, Water, Oxygen, Shelter, and Air
- Food: For energy and growth
- Water: For various cellular activities
- Oxygen: For respiration
- Shelter: For protection from the environment
- Air: For respiration
