51 Cards in this Set

  • Front
  • Back
what modifies and transports proteins and synthesizes and transports organelles
endoplasmis Reticulum
the endoplasmic reticulum is made up of...
the smooth ER and rough ER
secretory proteins and membranes are manufactored here, contains ribosomes
rough ER
important in lipid synthesis, detoxification and calcium storage, do not contain ribosomes
smooth ER
packaging and delivering sytem that handles incoming lipids and proteins
golgi apparatus
creates lysosome
golgi apparatus creates...
modifies, stores and routs profucts of ER, alters membrane phospholipids, targets productivity for parts of cell
golgie appartus that modifies, stores and routes.....
contains _________ to ________ macromolecules
digestive enzymes; digest; property of lysosomes
garbage disposal of cell
lysosomes
capture food materials and unwanted thinkgs and realease toxic materials
vacuoles
formed because of the central vacuole
turgor pressure
helps maintain fluid balance, determines size of cell
turgor pressure functions
food vacuole is formed by...
phagocytosis
plant cells, stores organic molecules, separates toxic by products, contributes to cell growth
central vacuole
only in plant cells for protection and gives plants a solid structure
cell wall
prevents excess consumption of water
cell wall prevents...
used for keeping organelles inside and has 2 bilayers made out of phospholipids
cell membrane
the cell membrane is
selectively permeable and used for diffusion and protein transport
in animal cells...extracellular matrix
is make of glycoproteins and is most abundant is collagen
extraceulluar matrix helps
cointrol cell behavior and influence of genes
intercellular junction
help integrate cells into higher levels of structure and funtion and gap juntions (communicatiing) and tight
nuclear is envelope is a ______ membrane
double bounc
involved in production of ribosomes and where ribosomal RNA is synthesized
nucleolus
mitosis- fibers curl up and become thick to seperate structure and become...
chromosomes...these fibers are chromatin
created in nucleas and pass thru nucelar pores to cytoplasm and combine to form ribosomes
ribsomal units
free ribomes are
located in cytoplasm
bound ribosomes are
attached to endoplasmic or nuclear envelope
cellular support, compose of ciliar and flagella, and separation of chromosomes during cell division
microtubules
participate in muscle contraction and localize cell contractions
microfilaments
bearing tension and inconsisten diamete from cell to cell
intermediate filaments
permanent fixtures in cells which maitain cell shapes
what is intermediate filaments
double membrane power house that is the site of respiration and generates ATP from sugars and fats
mitochondria (self-replicating)
its matrix contains DNA, Ribosomes, and enzymes
mitochondria's matrix
double membrane and self-replicating that contrains chlorophyll and mesophyll of plant and algae
chloroplast
flattened sacs
thylakaas
rids body of toxic substance and bound by a single membrane and found in the liver
peroxisome (self-replicating)
breaks down fatty acids to be used by mitochondira and contrains enzymes that transfer hydrogen
peroxisome break down
endomembrane system includes
nuclear envelope--endoplasmic reticulum---golgi apparatus---lysosomes--- vacuoles---plasma membrane
fresh waters protozoans keep water balance
contractile vacuole
plasma membrane is a
selective barrier that allows passage of oxygen nutrients and wastes
cytoskeleton provides
structural support and functions in motility and motion
chloroplasts
carries out photosynthesis and contains grana, chlorophyll traps solar energy
centrioles
identical structure to basal bodies
not part of the endomembrane system
mitchondria and chlroplasts
(made by free ribosomes, small amt. of DNA, grow/reproduce their own iwthin the cell, and involved in energy transformation)
amyplasts
sotre starch, in roots and tubers
chromoplasts
non chlorophyll pigments responsible for non green colors
chromatin
dna and protein comples of threadlike ribers make up eukaryotic chromosome
space between the cell membrane and nucleus
cytoplasm
the cytoplasm contains...
organelles and cytosol, which is a fluid
plant cells lack
lysosomes, centrioles, and flagella
animal cells lack
chloroplasts, central vacuole and tonoplast, cell wall, and plasmodermata
