Eukaryotic Cell Parts Flashcards
Nucleus
Directs the cell’s activities (control center of the cell)
Nucleolus
Makes ribosomes
Chromatin
a complex of DNA and proteins that forms chromosomes within the nucleus of eukaryotic cells
Nuclear membrane/envelope
serves to separate the chromosomes from the cell’s cytoplasm and other contents
Rough endoplasmic reticulum
Produces proteins for the rest of the cell to function
Smooth endoplasmic reticulum
produce and move lipids, an essential component of a cell’s outer membrane, and steroids
Vacuole
store nutrients and water on which a cell can rely for its survival.
Centrioles
help in the formation of the spindle fibers that separate the chromosomes during cell division
Mitochondrion
Powerhouse of the cell, converts stored energy in food to energize cell
Golgi apparatus
A structure in a cell that receives proteins and other newly formed materials from the endoplasmic reticulum, packages them, and distributes them to other parts of the cell
Lysosome
An organelle that breaks down the large food particles into smaller ones
Cell membrane
The semipermeable membrane surrounding the cytoplasm
Ribosomes bound to the Rough ER
Make proteins
Free ribosomes
Make proteins that function in the cytosol
Cytoplasm
fills the region between the cell membrane and the nucleus and is a gel-like substance that holds organelles in place
