The different structures of the cell
The different structures of the cell
Cell Wall: a rigid coveringCell Wall: a rigid covering
Rigid outer layer found in plant and bacteria cells.
Provides protection from physical injury
Provides skeletal support. Contains openings that
make it totally permeable.

Plasma Membrane: the fluid gatePlasma Membrane: the fluid gate Composed of protein
of lipid (fat) molecules.
Acts as a boundary to contain cytoplasm
Selectively permeable membrane to select chemicals that can pass in and out of cells.

Cytoplasm: the medium for movementCytoplasm: the medium for movement
Jelly-like material that fills cells.
Made mostly of water. Serves as a “molecular
soup” in which organelles are suspended in.
The medium for transport.

Cytoskeleton: the scaffoldingCytoskeleton: the scaffolding
Microtubules and microfilaments provide structure and support for the cell.

Nucleus: the command centerNucleus: the command center
Consists of nuclear envelope, nucleolus, chromatin, and nucleoplasm
Long thin strands of chromatin (DNA) contains instructions for cell metabolism and heredity.
Nuclear membrane has pores for movement of materials in and out of nucleus.

Endoplasmic ReticulumSmooth & Rough
Endoplasmic ReticulumSmooth & Rough
Large workspace for the cell. “Rough” appearance due to the
presence of ribosomes “Smooth” ER connected to
Rough ER. Smooth ER has different
functions for different cells. Storage of enzymes, and the production and storage of lipids.

Mitochondria: Power packsMitochondria: Power packs
Create ATP - the cell’s chemical energy.
Can number from 1 to 1000’s inside eukaryotic cells.
Folds in the Cristae increase the surface area for addition production of ATP’s
Matrix inside contains hundreds of enzymes.

Golgi ApparatusGolgi Apparatus
Mainly devoted to processing the proteins synthesized in the endoplasmic reticulum (ER)
Modifies the proteins for distribution.

Lysosomes: Cleaning upLysosomes: Cleaning up
Contain powerful enzymes which can be used to break down large food particles into smaller molecules or destroy damaged organelles.
Might digest healthy organelles to provide the cell with extra energy.

Vacuoles:Storage and packaging
Vacuoles:Storage and packaging
Membrane-bound sacs found in cytoplasm. Same type of material as the plasma membrane.
Help in waste disposal, transport, storage, and growth.
Much larger in plant cells. They aid in giving the plant cell support when filled with water.
Also store important substances like salts, minerals, and nutrients.
Contractile vacuoles are specialized to pump water out of the cell.

Vesicles: transport carriesVesicles: transport carries
Small vacuoles Usually formed at
Golgi apparatus. Carry protein
molecules to other organelles or the plasma membrane.
