Unicellular and Multicellular Organisms

Multicellular and Unicellular
Organisms
By: Owen and Ian Classification of Organisms Plants Adios Unicellular Organism - One cell
- Living things
- Live everywhere
- Millions of types
- Many are essential for life
- Can be fungi, bacteria, or protists Gas Exchange Multicellular Organisms Nutrition Specialized Cells Animals Fungi Bacteria Protists Phytoplankton Ameoba Bacteria - More then one cell
-Have specialized cells
-Many have trillions of cells
- Relies on cells for specific functions
- Can be plants, animals, fungi, or protists Bunny Tulips Fungi Specialized Animal Cells Skin Cells - "Gatekeepers" Muscle Cells - Transform energy -Bone Cells -Provides structure Nerve Cells - Transmit electrical impulse Brain Cells - Receive and transmit impulses Fat cells - Store energy Specialized Plant Cells Cells in leaves - Chloroplasts help make food Cells in stems -Transports food and water Cells in roots - Store food and water
- Transport these to stem Plants - Roots absorb water and minerals
- Xylem vessels carry these to the plant
- Leaves use photosynthesis to make food
- Phloem vessels carry this to the plant
- Stems and roots store extra sugars Animals - Eating living things (e.g. meat, vegetables)
- Eating products that come from living things (e.g. honey)
- Have a digestive system to break down food Vertebrates - Exchange gas in different ways
- Could use gills (e.g. fish)
- Could use skin (e.g. frog)
- Could use mouth and nose (e.g. human) Plants - Uses tiny openings (stomates)
- Let water and gases in and out
- Usually found on leaves and stems We hope you enjoyed the presentation.
