Epithelial Cell


Animal cell
Animal Cell

  • Bodies of all organisms are made of cells.

  • Without cells there is no life.


Cell membrane
Cell Membrane

  • Double layer of lipids with proteins for cell activity.

  • The proteins are receptors, pores, and enzymes.

  • Lipid layer (phospholipids) is a water-fearing molecule.

  • Responsible for controlled entry/exit of substances

Drawing of a cell membrane


Nucleus
Nucleus

  • Brain of the cell.

  • Controls all parts of the cell and its functions.

  • A membrane-bound organelle. (Dbl mbrn)

  • Communicates using nuclear pores.

  • DNA is found here.

  • Prominent structure is the nucleolus.

    • Nucleolus produces ribosomes & RNA

The cell nucleus


Mitochondria
Mitochondria

  • Provide cell with energy through respiration.

  • Double membrane-bound organelles.

    • Outer mmbrn smooth

    • Inner mmbrn twisted with cristae (folds)

  • On the cristae, sugar combines with O2 to form ATP (energy source).

Nuclear Power Plant


Golgi bodies
Golgi bodies

  • Single membrane-bound structure.

  • Packaging and shipping of a cell.

  • Packages are fluid-filled & called vesicles.

  • Vesicles transport large molecules in cells.

Golgi bodies


Ribosome
Ribosome

  • Site of protein synthesis.

  • Read code found in RNA.

  • Assemble proteins cell’s need for growth and different functions.

Ribosome pic


Endoplasmic reticulum
Endoplasmic Reticulum

  • Connects outer nuclear membrane with the cell membrane.

  • Function as channels within the cell.

  • Two types: Smooth and Rough.

    • Smooth are for fat and membrane protein production.

    • Rough have ribosomes on its surface and synthesize other proteins

Endoplasmic reticulum


Vacuole
Vacuole

  • Membrane organelles that store substances.

  • Vacuoles move substances in and/or out of the cell.

  • Movement in or out of the cell is down by fusing with the cell membrane.

Vacuole


Plant cells
Plant Cells

  • Have 2 or more organelles than the animal cell:

    • Cell Wall

    • Chloroplast

  • The vacuole is larger in plant cells


Cell wall
Cell Wall

  • Used to support the plant.

  • Made of fiber called cellulose.

    • Cellulose is not digested by living organisms (COLON CLEANSE!)

  • Connected to cell membrane

Plant Cell Wall


Chloroplast
Chloroplast

  • Site for photosynthesis

  • Photosynthesis is when sunlight, H2O, and CO2 are use to make glucose and oxygen

  • Chlorophyll is a green pigment found here.

  • Chlorophyll collects the sun’s energy.

Chloroplast
