Animal Cell Flashcards
What are animal cells?
Animal cells are eukaryotic cells or cells with a membrane-bound nucleus.
What are organelles?
Organelles are different parts of a cell.
It is composed of phospholipid bilayer with embedded proteins and carbohydrates.
Cell Membrane
What type of membrane allows Oxygen and CO2 to enter?
Semipermeable Membrane
What are microvilli (microvillus)?
Microvilli are finger-like folds cell membrane that boost the cell’s absorption function. It also increases the cell’s surface area.
It is a fluid containing cytosol that fills the cell. This is where the molecules first pass through after entering or before exiting the cell membrane. This is also where the organelles are found and move freely.
Cytoplasm
It is a fluid that contains electrolytes. This is the site of cytosolic activities like signal transduction, DNA transcription and replication, glycolysis, enzyme activities, etc.
Cytosol
It is substance that produces electrically conducting solutions, metabolites, and other substances produced during metabolism.
Electrolytes
It is the conversion of glucose into another form
Glycolysis
What provides the structure or shape of the cell.
Cytoskeleton
What are the three major filaments in the cytoskeleton?
- Microfilament
- Microtubule
- Intermediate Filament
This filament is composed of actin (contractile protein) and is about 7 nanometer.
Microfilament
This filament is composed of tubulin (globular proteins) and is about 26 nanometer.
Microtubule
This filament provides tensile strength in the cell and is about 10 nanometer
Intermediate Filament
It comes in pairs and are at right angles with each other. They help in the separation and transfer of chromosomes.
Centrioles
