Cell Diversity

Unicellular Organisms All organisms are made of cells, but sometimes a cell is the organism A unicellular organism is an organism made of one cell

Multicellular Organism Multicellular organism are organisms made up of many cells Cells throughout an organism can develop in different ways to perform different tasks this is called cell specialization

Levels of Organization The levels of organization in a multicellular organism are: Cells tissues organs organ systems

Two Types of Eukaryotic Cells Plant Cells Animal Cells Plant and Animal cells have traits in common and traits that differ Traits of both plant and animal cells: Nucleus Cell membrane Cytoplasm

Plant Cells Have a cell membrane AND cell wall Contain chloroplasts Contain a large vacuole (for water storage)

Animal Cells Have only a cell membrane Contain the organelle centriole
