The Cell Flashcards
plasma membrane
barrier between intracellular/extracellular compartments & controls what goes in/out of the cell
cytoplasm
provides strength, structure, and support, and maintains cell shape.
nucleus
Control center of a cell. Spherical or oval structure, dark in appearance.
centriole
duplicate prior to cell division and help anchor spindle fibers (barrel-shaped).
mitochondria
site of cellular respiration which produces ATP.
ribosomes
site of protein synthesis (makes proteins).
rough endoplasmic reticulum
produces, modifies and packages secretory proteins.
golgi apparatus
refines and alters molecules intended for both secretion and internal use. produces lysosomes.
lysosome
digestion of absorbed material and internally produced waste.
inclusion bodies
storage granules.
proteasome
responsible for breaking down individual misfolded or abnormal protein molecules.
microtubules
forming of the mitotic spindle during cell division.
intermediate filaments
resist pulling forces.
microfilaments
cellular muscle
nuclear pores
the hole that transports mRNA out
chromosomes
carry the basic genetic material – DNA.
chromatids
an unwinded version of a chromosome.
centromere
part where the chromatids attach.
nuclear envelope
separates the nucleus from surrounding cytosol
chromatin
DNA portion contains sequence code for making proteins and enzymes that control molecular interactions.
nucleolus
location of synthesis of ribosomal subunits.
cytosol
helps transport molecules inside cell and supports cell membrane.
smooth endoplasmic reticulum
produces, modifies, and packages lipids and carbohydrates.
peroxisome
detoxify various molecules such as alcohol and formaldehyde
