Objective The student at the end of the lesson will recognize:  Parts of the animal cell.  Functions of the organelles in the animal cell.

End Click on each of the names for reading organelles features

Nucleolus  Inside nucleus  Contains RNA to build proteins End Animal Cell

Nucleus  Directs cell activities  Separated from cytoplasm by nuclear membrane  Contains genetic material –DNA Nuclear membrane  Surround nucleus  Made of two layers  Opening allow material enter and leave nucleus Chromosomes  In nucleus  Made of DNA  Contains instruction for traits and characteristics End Animal Cell

Ribosomes  Each cell contains thousands  Make proteins  Found on ribosomes and floating thought the cell. End Animal Cell

Endoplasmic Reticulum Moves material around in cell Smooth type: lacks ribosomes Rough type: ribosomes embedded in surface End Animal Cell Rough Smooth

Golgi Apparatus  Golgi apparatus is one of the important organelles found in eukaryotic cells.  Directing the carbohydrates and proteins, needed by the body, to their proper destination is the main function of this cell organelle.  In the process of directing protein and carbohydrate molecules to their appropriate destinations, they are tagged with details about the destination and structural modifications.

Plasmatic Membrane  Outer membrane of cell that controls movement in and out of the cell  Double layer End Animal Cell

Cytoskeleton  The cytoskeleton (also CSK) is a cellular scaffolding or skeleton contained within a cell's cytoplasm.  The cytoskeleton is present in all cells; it was once thought to be unique to eukaryotes, but recent research has identified the prokaryotic cytoskeleton.  It forms structures such asflagella, cilia and lamellipodia a nd plays important roles in both intracellular transport (the movement of vesicles and organelles, for example) and cellular division. End Animal Cell

Mitochondrion  Produce energy through chemical reactions – breaking down fats and carbohydrates  Control level of water and other materials in cell  Recycles and decomposes proteins, fats and carbohydrates End Animal Cell

Cytoplasm  Gel-like mixture  Surrounded by cell membrane  Contains hereditary material End Animal Cell

Lysosome  Lysosomes are the cell's waste disposal system and can digest some compounds  Transport undisgested material to cell membrane for removal  Cell breaks down if lysosome explodes End Animal Cell

Centrioles  A centriole is a cylinder shaped cell structure found in most eukaryotic cells, though it is absent in higher plants and most fungi.  An associated pair of centrioles, arranged perpendicularly and surrounded by an amorphous mass of dense material, called the pericentriolar material, or PCM, makes up a compound structure called a centrosome.  Centrioles are involved in the organization of the mitotic spindle and in the completion of cytokinesis End Animal Cell
