Textbook Organelles Flashcards
motility structure present
flagellum
composed of a cluster of microtubules
flagellum
an
extension of the plasma
membrane
flagellum
region where the cell’s microtubules are initiated
Centrosome
contains a
pair of centrioles
Centrosome
reinforces cell’s shape
Cytoskeleton
components are made of
protein
Cytoskeleton
functions in cell movement
Cytoskeleton
membrane projections that
increase the cell’s
surface area
Microvilli
organelle with various specialized metabolic functions
peroxisome
produces hydrogen peroxide as a by-product and
then converts it to water
peroxisome
where cellular respiration occurs and
most ATP is generated
mitochondria
digestive organelle where macromolecules are
hydrolyzed
lysosome
organelle active in synthesis, modification, sorting,
and secretion of cell products
golgi apparatus
complexes that make proteins
ribosomes
free in cytosol or bound to rough ER or nuclear
envelope
ribosomes
membrane
enclosing the cell
plasma membrane
involved in production
of ribosomes
nucleolus
active in membrane synthesis and other synthetic and metabolic processes
endoplastic reticulum
outer layer that maintains cell’s shape and protects cell from mechanical damage
cell wall
made of cellulose
cell wall
cytoplasmic channels through cell walls that connect the cytoplasms
of adjacent cells
plasmodesmata
photosynthetic organelle
Chloroplast
converts energy of sunlight to chemical energy
stored in sugar molecules
chloroplast
prominent organelle in older plant cells
central vacuole
functions include storage, breakdown of waste products, and hydrolysis of macromolecules
central vacuole
enlargement of the
vacuole is a major mechanism of plant growth
central vacuole
