Common Misconception: Because of the ways cells are portrayed, with only a few representatives of each organelle shown, students may think of a cell as a bag of cytoplasm with a loose assortment of organelles floating about.
Correcting the Misconception: Quantitative analysis of cell material shows that the parts of the cell are so numerous that they constantly bump up against one another and agaisnt the cell membrane and cytoskeloton.

33. PLANT VERSUS ANIMAL CELL
PLANT CELLS :
- HAVE CHLOROPLASTS (for photosynthesis—makes sugar)
- NO CENTRIOLES
- HAVE A CELL WALL AND CELL MEMBRANE
- HAVE A LARGE VACUOLE
ANIMAL CELLS :
-NO CHLOROPLASTS
-HAVE CENTRIOLES
-HAVE A CELL MEMBRANE BUT NO CELL WALL
-HAVE SMALL VACUOLES

34. Cell Summary Cells have 3 main jobs make energy need food + O2
cellular respiration & photosynthesis
need to remove wastes
make proteins
need instructions from DNA
need to chain together amino acids & “finish” & “ship” the protein
make more cells
need to copy DNA & divide it up to daughter cells
Our organelles do all those jobs!
