Function Of Organelles Flashcards
What does the cytoskeleton do
Provides structural framework for cells
Aids in movement of cellular structure
What are the 3 type of filaments that cytoskeleton is made of
Microtubules
Intermediate filaments
Micro filaments
What do microvilli do
Increase surface area for absorption of extra cellular materials
What do cilia do
Move materials over cell surfaces and remove microbes and debris from lungs
What is the nucleus
Fluid structure containing enzymes, proteins and genetic material, together controlling cellular function
what is the endoplasmic reticulum (ER)
Network of membranous sheets and channels that extend through the cytoplasm
What is the Golgi apparatus
Stacks of flattened membranes containing chambers that modify and store secretory products and lysosomal enzymes
What are lysosomes
Contain enzymes that digest material
Major degrative compartment of the cell
What are proteosomes
Contain proteases that breakdown and recycle damaged or normal intracellular proteins
Proteins are tagged with a molecule called ubiquitin to signal removal
What is the mitochondria
Powerhouse of the cell
Makes physiological energy - ATP
