  • 1. COMMON CELL TRAITS
    • Acellis the smallest unit that is capable of performinglife functions .

2. COMPARING CELLS

  • Thesize&shapeof a cell relates to itsfunction . (job it does)

3. Prokaryotic Cells (proh KAYR ee yah tihk)

  • cellswithoutmembrane-bound structures
  • EX :bacteria
  • pond scum

4. Eukaryotic Cells (yew KAYR ee yah tihk)

  • cellswithmembrane-bound structures
  • EX:animals ,plants ,fungiandprotists

5.

  • protectsthe cell
  • givesshape
  • is made ofcellulose
  • A cell wall is found inplants ,algae ,fungi , & mostbacteria .

CELL WALL 6. CELL MEMBRANE

  • Outer covering,protective layeraroundALLcells
  • For cells with cell walls,the cell membrane isinside the cell wall
  • Allowsfood ,oxygen , &waterinto the cell &wasteproducts out of the cell.

7. CYTOPLASM

  • gelatin-likeinside cell membrane
  • constantlyflows
  • akaprotoplasm

8. NUCLEUS

  • Directs allcell activities
  • Containsinstructionsfor everything the cell does
  • These instructions are found on ahereditarymaterial calledDNA
  • Usually thelargestorganelle

9. NUCLEAR MEMBRANE

  • separatesnucleusfromcytoplasm
  • controls movement of materialsin & outof nucleus
