Biology ( Cell 2 )

Cytoskeleton

A framework of the cell within the cytoplasm ( Eukaryotic cells )

Microtubles

Long, hollow protein cylinders that form a rigid skeleton for the cell / assist moving substances within the cell.

Microfilaments

Thin protein threads that help give the cell shape / enable the entire cell or parts of the cell to move.

Centrioles

Organelles that occur in pairs and are more important for cell division ( Animal / most protist cells )

Cilia

Projections from cell surfaces that aid in locomotion and feeding; also used to sweep substances along surface ( Some animal / protist / prokaryotes cells )

Flagella

Longer / less numerous than Cillia

Nucleus

Control center of the cell containing coded directions for the production of proteins / cell division ( Eukaryotic cells )

Nucleolus

Ribosome production inside the nucleus

Mitochondria

Membrane-bound organelle that makes energy available to the rest of the cell ( Eukaryotic cells )

Chloroplasts

Double-membrane organelle where photosynthesis takes place ( Plant / some protist cells )

Ribosome

Organelle of protein synthesis

Endoplasmic reticulum

Highly folded membrane of protein synthesis ( rough / smooth endoplasmic reticulum )

Goldi apparatus

Flattened stack of tubular membranes modifying proteins and packages them for distribution outside the cell ( Eukaryotic cells )

Lysosomes

Vesicle breaking down excess / worn-out cellular substances

Cell wall

Inflexible barrier that provides support / protects the plant cell

Vacuole

Membrane-bound vesicle for the temporary storage of materials
