Lab: Cell Structure and Function Flashcards
Cell membrane
the thin membrane that surrounds every living cell
Centrioles
A centriole comprises nine bundles of microtubules that are hollow tubes arranged in a ring
Chromatin
chromatin is a complex of DNA and protein found in eukaryotic cells. The primary function is to package long DNA molecules into more compact, denser structures.
Cilia
cilia are small, slender, hair-like structures present on the surface of all mammalian cells.
Flagellum
a microscopic hair-like organelle used by cells and microorganisms for movement
Golgi apparatus
a complex of vesicles and folded membranes within the cytoplasm of most eukaryotic cells, involved in secretion and intracellular transport.
Lysosomes
a lysosome is a membrane-bound cell organelle that contains digestive enzymes.
Microtubules
microtubules, with intermediate filaments and microfilaments, are the components of the cell skeleton which determine the shape of a cell.
Microvilli
any of numerous microscopic bristlelike protrusions that occur on the surface of a wide variety of cell types.
Mitochondrion
an organelle found in large numbers in most cells, in which the biochemical processes of respiration and energy production occur.
Nuclear Envelope
a double membrane layer that separates the contents of the nucleus from the rest of the cell.
Nucleolus
a small dense spherical structure in the nucleus of a cell during interphase.
Nucleus
the membrane-enclosed organelle within a cell that contains the chromosomes.
Peroxisome
a small organelle present in the cytoplasm of many cells, which contains the reducing enzyme catalase and usually some oxidases.
Ribosome
a minute particle consisting of RNA and associated proteins found in large numbers in the cytoplasm of living cells.
