|
biosynthetic-secretory pathway
|
The process used by eucaryotic cells to synthesize proteins and lipids, followed by secretion or delivery to organelles or the plasma membrane; involves the endoplasmic reticulum, Golgi apparatus, and secretory vesicles.
|
|
|
cilia
|
Threadlike appendages extending from the surface of someprotists that beat rhythmically to propel them; cilia are membrane-bound cylinders with a complex internal array of microtubules, usually 9+2 pattern.
|
|
|
cristae
|
infoldings of the inner mitochondrial membrane
|
|
|
cytoskeleton
|
A network of microfilaments, microtubules, intermediate filaments, and other components in the cytoplasm of eucaryotic cells that helps give them shape, functions during cell division, and helps move materials in the cytoplasm.
|
|
|
endocytosis
|
The process in which a cell takes up solutes or particles by enclosing them in vesicles pinched off from its plasma membrane
|
|
|
endoplasmic reticulum (ER)
|
A system of membranous tubules and flattened sacs (cisternae) in the cytoplasm of eucaryotic cells; rough endoplasmic reticulum (RER) bears ribosomes on its surface; smooth endoplasmic reticulum (SER) lacks ribosomes
|
|
|
Flagellum
|
A thin, threadlike appendage on many procaryotic and eucaryotic cells that is responsible for their motility.
|
|
|
Golgo apparatus
|
A membranous eucaryotic organelle composed of stacks of flattened sacs (cisternae), which is involved in packaging and modifying materials for secretion and many other processes.
|
|
|
Lysosome
|
A spherical membranous eucaryotic organelle that contains hydrolytic enzymes and is responsible for the intracellular digestion of substances.
|
|
|
Microfilaments
|
Protein filaments, about 4 to 7 nm in diameter, that are present in the cytoplasm of eucaryotic cells and play a role in cell structure and motion.
|
|
|
Mitochondrion
|
The eucaryotic organelle that is the site of cellular respiration; it provides most of a nonphotosynthetic cell's energy under aerobic conditions.
|
|
|
Nuclear envelope
|
The complex double-membrane structure forming the outer boundary of the nucleus.
|
|
|
Nucleolus
|
Anorganelle located within the nucleus and not bounded by a membrane; it is the location of fibosomal RNA synthesis and assembly of ribosomal subunits.
|
|
|
Nucleus
|
The eucaryotic organelle enclosed by a double-membrane envelope that contains the cell's chromosomes.
|
|
|
Organelle
|
A structure within or on a cell that performs specific functions and is related to the cell in a way similar to that of an organ to the body.
|
|
|
Phagocytosis
|
The endocytotic process in which a cell encloses large particles in a membrane-delimited phagocytic vacuole (phagosome) and engulfs them.
|
|
|
Thylakoid
|
A flattened sac in the chloroplast stroma that contains photosynthetic pigments and the proteins and other molecules that convert light energy into ATP
|
