Midterm Study Guide Pt. 2 Flashcards
Where is the plasma membrane located?
envelopes entire cell
What is the primary function of the plasma membrane?
- provides a selectively-permeable barrier for the cell
- regulates movement of material in and out of cell
Where is the cytoplasm located?
interior of the cell
What is the primary function of the cytoplasm?
region of cellular metabolism and other activities that maintain the cell
Where is the cytosol located?
- interior of cell
- surrounds organelles
What is the primary function of the cytosol?
allows the transport of substances within cell
Where are organelles located?
within the cytoplasm, suspended within cytosol
What is the primary function of organelles?
each type of organelle conducts specific cellular functions
Where are centrioles located?
near the nucleus in the centrosome
What is the primary function of centrioles?
participates in cell division
Where is cilia located?
extend outward away from cell surface
What is the primary function of cilia?
motile cilia are used to propel fluids or small particles
Where is flagella located?
protrudes through cell membrane to the exterior of the cell
What is the primary function of flagella?
movement of the cell
Where is ribosome located?
often attached to the ER or unattached in cytoplasm
What is the primary function of ribosome?
sites of protein synthesis
Where is Rough ER located?
extends from the nuclear envelope within the cytoplasm
What is the primary function of Rough ER?
sites of protein synthesis
Where is Smooth ER located?
within cytoplasm
What is the primary function of Smooth ER?
sites of lipid and carbohydrate assembly
Where is Golgi apparatus located?
within cytoplasm, usually near the nucleus
What is the primary function of Golgi apparatus?
prepares and packages proteins for transport
Where is mitochondria located?
throughout cytoplasm
What is the primary function of mitochondria?
site of cellular respiration where ATP is produced
Where is lysosome located?
throughout cytoplasm
What is the primary function of lysosomes?
contain enzumes that break down waste material and cellular debris
Where are vesicles located?
throughout cytoplasm, usually near the Golgi apparatus
What is the primary function of vesicles?
transport of materials within the cell
Where is the nucleus located?
often located at the center of the cell
What is the primary function of the nucleus?
contains genetic material which regulates protein synthesis and cell division
Where is the nucleolus located?
within the nucleus
What is the primary function the nucleolus?
site of RNA synthesis (transciption)
Where is the nuclear envelope located?
envelops the nucleolus and nucleoplasm
What is the primary function of the nuclear envelope?
- provides a selectively-permeable barrier
- regulates movement of material in and out of nucleus
Where is the nucleoplasm located?
contained within the nuclear envelope and surrounds chromosomes and nucleoli
What is the primary function of the nucleoplasm?
contains materials associated DNA and RNA synthesis
Where is the chromatin located?
throughout nucleoplasm
What is the primary function of chromatin?
genetic material which controls protein synthesis
