Basic Structure of a Cell

Page
3

Dead layer

Large empty spaces present between cellulose fibers

Freely permeable

Cell wall

Slide 25

Plant Cell

Made of cellulose which forms very thin fibers

Strong and rigid

Found in plant cells

Slide 26

Protect and support the enclosed substances (protoplasm)

Resist entry of excess water into the cell

Give shape to the cell

Cell wall

Plant Cell

Slide 27

Plant Cell Organelles

Have a large central vacuole

Surrounded by tonoplast

Contains cell sap

Sugars, proteins, minerals, wastes, & pigments

Slide 28

Different kinds of plant cells

Slide 29

mitochondrion

nucleus

glycogen granule

cell membrane

cytoplasm

Animal cell

No cell wall or chloroplast

Stores glycogen in the cytoplasm for food energy

vacuole

Slide 30

Animal Cell Organelles

Near the nucleus

Paired structures

Help cell divide

Slide 31

Different kinds of animal cells

Slide 32

Similarities between plant cells and animal cells

Both have a cell membrane surrounding the cytoplasm

Both have a nucleus

Both contain mitochondria

Slide 33

Differences between plant cells and animal cells

Animal cells

Plant cells

Relatively smaller in size

Irregular shape

No cell wall

Relatively larger in size

Regular shape

Cell wall present

Slide 34

Animal cells

Plant cells

Vacuole small or absent

Glycogen as food storage

Nucleus at the center

Large central vacuole

Starch as food storage

Nucleus near cell wall

Differences between Plant Cells and Animal Cells

Slide 35

Compound Microscope

Instrument for observing small objects

Magnify images up to 2000X their size

Slide 36

Different parts of a microscope
