The Animal CellKey Concept: Eukaryotic cells contain membrane bound organelles
  • All living things are composed of cells
  • Eukaryotic cells contain membrane-bound organelles
cell membrane plasma membrane
Cell Membrane/Plasma Membrane
  • Barrier to extra-cellular environment
  • Allows nutrients in and wastes out
  • Identifies the cell
  • Receives messages from other cells
nucleus
Nucleus
  • Controls the cells activities
  • Contains the genetic material (DNA)
  • Surrounded by a nuclear membrane
nucleolus
Nucleolus
  • Manufactures ribosomes
nuclear membrane
Nuclear Membrane
  • Keeps the DNA inside
  • Allows the RNA to pass into the cell
cytoplasm
Cytoplasm
  • Gel-like fluid that fills the cell
  • Breaks down some glucose for energy (glycolysis) – not much energy
  • Filled with free-floating subunits
mitochondria
Mitochondria
  • Metabolizes glucose for energy – provides a great deal of energy
  • Has its’ own DNA
  • Has a double membrane
endoplasmic reticulum
Endoplasmic Reticulum
  • Two types of ER
    • RER (rough endoplasmic reticulum) contains ribosomes
    • Manufactures and transports proteins
    • SER (smooth endoplasmic reticulum) has no ribosomes
    • Manufactures and transports lipids
ribosome
Ribosome
  • Makes proteins
  • Sometimes attached to RER
  • Sometimes free-floating in the cytoplasm
golgi apparatus
Golgi Apparatus
  • Packages proteins
  • Modifies proteins
  • Prepares them for export to the organism outside the cell
vesicle
Vesicle
  • Transports proteins to and from the Golgi apparatus
lysosome
Lysosome
  • Digests worn out organelles
  • Destroys infected or un-necessary cells
  • Contains digestive enzymes
centriole
Centriole
  • The centriole is found only in animal cells
  • It is involved in cell division
plant cells
Plant Cells
  • Plant cells have many of the same organelles as animals cells
plant cells have 2 extra organelles
Plant Cells Have 2 Extra Organelles
  • Outside the cell membrane, plants have a cell wall
  • Plants have large central vacuoles
  • Plants have chloroplasts to convert sunlight to glucose
chloroplasts
Chloroplasts
  • Use CO2, H2O and sunlight to produce Carbohydrates
  • Releases O2
  • Contains double membrane
  • Has its’ own DNA
chloroplast
Chloroplast
  • Chlorophyll does the work
  • Chlorophyll is located in the thylakoid stacks
  • Thylakoid stacks are called granum
shape and support
Shape and Support
  • Made of cellulose (an indigestible form of carbohydrate)
  • Found just outside the plasma membrane
transport into out of the cell
Transport Into & Out of the Cell
  • Materials move from areas of high concentration to areas of low concentration
  • This is called diffusion
