Lab 1st Exam - Parts of the Cell
Cell terminology that will be present in the 1st Lab exam and the 2nd Lecture exam for Dr. Kendall's class. FUNCTION OF THE ORGANELLE WILL BE IN BOLD!
Plasma Membrane (Cell)
The outermembrane of the cell.
Regulates the transport of certain materials into and out of the cell.
A fluid-like environment between the nucleus and the cell membrane in which organelles are found. (Made up of Cytosol and Cytoskeleton)
Liquid substance of the cytoplasm
which acts like a cushion for organelles.
Support and framework for cells.
Made up of microfilament, intermediate filament and microtubules.
Surrounded by its own membrane.
Contains celluar DNA/genetic info.
Nuclear Membrane (Envelope)
Two lipid bi-layers that surround nuclear contents.
Has pores that permit and regulate passage of materials between cytoplasm and nucleus.
Dark staining granule found within the nucleus.
It is involved with the synthesis of ribosomal RNA.
Thread like material within the nucleus that
A series of channels associated with
storage, synthesis, and the transport of substances within the cell.
Rough Endoplasmic Reticulum (RER)
Contains ribosomes and
Smooth Endoplasmic Reticulum (SER)
Does NOT contain ribosomes;
Attached to the endoplasmic reticulum or as free bodies.
Sites of protein synthesis.
Powerhouses of the cell.
Sites of the production of ATP (energy) in the cell.
Golgi Apparatus (Complex)
Synthesizes, packages, and secretes cellular products out of the cell.
Small sac-like structures that contain powerful digestive enzymes.
Digests macromolecules, microorganisms, and old or damaged organelles.
Large storage site in a cell surrounded by a membrane which may contain water or other materials.
has many different functions.
Small storage site.
Involved in transportation of materials into and out of the cell. Also transports proteins from the RER to the Golgi Apparatus.
Cylindrical structures assisted in mitosis. (cell division)
Microtubules and Filaments
Provides cellular support, transport, and maintains cell shape.
Microtubles form spindle during mitosis.
Small sac-like structures that contain oxidative enzymes.
Detoxifies hydrogen peroxide, alcohol, and other harmful substances.
Hair like projectiles.
Oscillates mucous, cells, and debris over cell surface.
Facilates transport and absorption (nutrients) across membrane and increases surface area.
(ex. digestive tract)
The 3 parts of most cells that can be viewed by a light microscope.
A very powerful microscope that can be used to view organelles within the cytoplasm.
Contractile protein fibers;
play a role in movement of cell and organelles.
(found in microvilli)
A component of the cytoskeleton that includes filaments intermediate in size between microtubules and microfilaments.
Structure present in the cytoplasm of animal cells, important during cell division;
functions as a microtubule-organizing center and has two centrioles.
A diffuse fibrous network surrounding a centrosome.
Present in the cytoplasm;
providing energy and storage of glucose.
Openings in the nuclear membrane that
allow certain materials into and out of the nucleus.
