Animal Cell Flashcards
are eukaryotic cells, or cells with a membrane-bound nucleus.
Animal cells
different parts of a cell.
Organelles
thin biological sheets of material that allow certain molecules to pass through them more easily than others. Allows oxygen and CO2 to enter.
Semipermeable Membrane
are finger-like folds cell membrane that boosts the cell’s absorption function. It also increases the cell’s surface area.
Microvilli (Microvillus)
fluid containing cytosol that fills the cell. This is where the molecules first pass through after entering or before existing the cell membrane. This is where the organelles are found and move freely.
Cytoplasm
fluid that contains electrolytes. This is the site of the cytosolic activities likes signal transduction, DNA transcription and replication, glycolisis, enzymes activities, etc.
Cytosol
substance that produces electrically conducting solutions, metabolites, and other subtances produced during metabolism.
Electrolytes
conversion of glucose into another form.
Glycolysis
provides the structure or shape of the cell.
Cytoskeleton
what are the three major filaments of the cytoskeleton?
Microfilament, Microtubule, and Intermediate Filament
composed of actin (contractile protein) and is about 7 nanometer.
Microfilament
composed of tubulin (globular protein) and is about 25 nanometer.
Microtubule
provides tensile strength in the cell and is about 10 nanometer.
Intermediate Filament
come in pairs and are at right angles with each other. They help in the separation and transfer of chromosomes.
Centrioles
it is where the microtubules get organized.
Centrosome
