FUNCTIONS OF ORGANELLES Q1 WK7 D5 EUKARYOTIC CELLS FUNCTIONS OF ORGANELLES Strand 4: Life Science Concept 1: The Cell PO2: Compare the form and function of prokaryotic and eukaryotic cells and their cellular components.

CELL MEMBRANE EXPLAIN: The cell membrane acts as a barrier that lets certain things in & out of the cell. Selectively Permeable- the membrane selects what is allowed in / out Allows certain things in and/or out. ALSO CALLED: SELECTIVELY PERMEABLE

CYTOPLASM (not cytoskeleton) SPACE Area of the cell between the nucleus and the cell membrane Gel-like material of the cell

MITOCHONDRIA (or Mitochondrion) Transforms energy from organic compounds (food) into ATP. Provides power for the cell ATP: chemical form of energy that the cell uses

The control center of the cell Stores the heredity information (DNA) NUCLEUS The control center of the cell Stores the heredity information (DNA)

Nucleolus The center of nucleus of eukaryotic cells The site where ribosomes are made Composed of proteins and nucleic acids

Allows specific things in / out of the nucleus NUCLEAR ENVELOPE Allows specific things in / out of the nucleus

ENDOPLASMIC RETICULUM Moves protein from one end of the cell to the other

Golgi Bodies (or Golgi Apparatus) Packages and refines proteins

LYSOSOME LYSOSOME: Cleans up the cell Digestive organelle; it has enzymes that removes old organelles & foreign substances.

Stores enzymes, metabolic waste and water VACUOLE Stores enzymes, metabolic waste and water

Converts energy from sunlight into organic energy in the cell CHLOROPLAST Converts energy from sunlight into organic energy in the cell *ONLY IN PLANT CELLS

CELL WALL Protects the cell Provides structure & support for the cell *ONLY IN PLANT CELLS

Directs the organelles that are involved with cell division (MITOSIS) CENTRIOLES Directs the organelles that are involved with cell division (MITOSIS) *ONLY IN ANIMAL CELLS End unit

SMOOTH ENDOPLASMIC RETICULUM (E.R.) NUCLEUS VACUOLE ROUGH ENDOPLASMIC RETICULUM (E.R) DNA CELL MEMBRANE GOLGI BODIES NUCLEAR ENVELOPE LYSOSOME CYTOPLASM Can use this slide to help students w/ Animal Cell coloring worksheet CENTRIOLES SMOOTH ENDOPLASMIC RETICULUM (E.R.) MITOCHONDRIA ANIMAL CELL
