Plant Cell vs. Animal Cell--their three major differences

1.) Plant cells have cell walls; animal cells don't--that's why the shape of plant cells is usually rectangular while animal cells can have many different, irregular shapes depending on their functions

2.) Plant cells have chloroplasts to turn sunlight into food; animal cells don't and therefore can't make their own food within the cells

3.) Plant cells usually have one large vacuole while animal cells have many small ones or none at all

Cell wall               
~In plant cells only; provides shape, support, protection to cell
~Is non-living
~School analogy: brick walls of school protect, support and give shape to school
~Your analogy:


Cell membrane   
~Surrounds cell, controls what goes in and out.
~School analogy: windows/doors of school allow people to go in and out
~Your analogy:
                        

Cytoplasm
~Gel-like substance that fills cell; where organelles are found.
~School analogy: Air fills school like cytoplasm fills cell
~Your analogy:


Organelles      
~Structures in cell that have special jobs


Mitochondrion (singular)
Mitochondria (plural)   
~Convert food to energy; “powerhouse” of cell
~School analogy: Generator creates electricity/energy for school
~Your analogy:


Vacuole 
~Storage space for cell—holds waste, water, food.                                     
~Plant cells--one large vacuole; animal cells--many small vacuoles or none at all
~School analogy: Bathrooms hold wastes; closets store paper, books
~Your analogy:

                        
Nucleus         
~Controls everything that happens in cell; “brain” of cell
~School analogy: Principal controls what goes on in school
~Your analogy:
                        

Chloroplast
~Converts sunlight into energy or food for cell—process called photosynthesis
~School analogy: Lunch ladies make us lunch
~Your analogy:

Notes on chapter 1 section 1: Discovering Cells (pages 6-13)

Cell—Basic unit of (structure and function in) all living things

Microscope—instrument that makes small objects look larger

Cell Theory
·      All living things are made of cells
·      Cells are the basic unit of (structure and function in) all living things
·      All cells are produced from other cells
