Parts Of The Cell And Their Functions Flashcards
The cell contains different part which carry out different functions
Organelles
Composed of phospholipid bilayer embedded with protein and carbohydrates
Cell membrane
It is _____, which means not everything can enter or pass through it
Semipermeable
In the cell membrane are several specialized fingerlike folds which mainly increase the surface area of the cell
Microvilli (singular: microvillus)
It contains tue semifluid substance called cytosol where the different organelles are suspended
Cytoplasm
4 different substance of cytosol
Electrolytes (produce electrically conducting solutions)
Metabolites (produced during metabolism)
Ribonucleic acid (RNA)
Synthesized proteins
2 physiological process of cytosol
Glycolysis
Protein and fat synthesis
The cytoplasm appears to have no form. However, it does have structure due to the presence of the
Cytoakeleton
3 major filaments
Microfilament
Microtubules
Intermeduate filament
A filament that has a diameter of about 7 nanometers (nm) and is mainly composed of a contractile protein called actin
Microfilament
A filament that has a diameter of about 25 nm and is composed of globular proteins called tubilins (alpha and beta tubulins). It helps form the shape of the cell as well as track the movement of the organelles
Microtubule
A filament that is about 10nm in diameter and is the most stable and the least soluble contituent of the cytoskeleton
Intermediate filament
Refers to the maximum stress that an object can withstand before it breaks
Tensile strength
These come in pairs and are at right angles with each other
Centrioles
Replicated genegic materials in the cells
Chromosomes
