PARTS OF THE CELL Flashcards
parts of the cells are called
ORGANELLES
meaning small organs
ORGANELLES
outer boundary of cell is
PLASMA MEMBRANE
plasma membrane is composed of a bilayer of
PHOSPHOLIPID MOLECULES
hydrophilic
water-loving
hydrophobic
water-fearing
large bubble with a double-walled membrane (nuclear envelope)
NUCLEUS
DNA
DEOXYRIBONUCLEIC ACID
DNA STRANDS
CHROMATIN
tiny nucleus
NUCLEOLUS
RNA
RIBONUCLEIC ACID
rRNA
RIBOSOMAL RIBONUCLEIC ACID
network of membranous tubes and canals winding through the interior of the cell
ENDOPLASMIC RETICULUM
canal with ribosomes
ROUGH ER
canal without ribosomes
SMOOTH ER
material within the plasma membrane
CYTOPLASM
site for protein synthesis
RIBOSOMES
stack of flattened sacs. the apparatus receives material from ER
GOLGI APPARATUS
site for ATP Synthesis or energy conversion
MITOCHONDRIA
vesicles containing digestive enzymes that digest foreign substances. they repair the plasma membrane.
LYSOSOMES
tiny hollow beams that form of the part of the cell skeleton. they also form the other cell organelles.
MICROTUBULES
CYTOSKELETON INCLUDE
MICROFILAMENTS and INTERMEDIATE FILAMENTS
dense area of cell fluid near the nucleus
CENTROSOME
centrosome contains a pair of
CENTRIOLES
tiny finger-like projections of the cell that increase the membrane’s surface area for more efficient absorption.
MICROVILLI
short, hair-like organelles that propel material along a cell’s surface.
CILIA
single, long hair-like organelles found in sperm cells
