Cell and Molecular Biology ( Day 11) Flashcards
all organism are composed of one or more cellls
Cell theory
schleiden & Schwann
the basic unit of life
Cell theory
Schleiden & Schwann
come from pre existing cells
Cell theory
Rudolf Virchow
General characteristics of a cell
bounded by a plasma membrane
contain semifluid cytosol in the cytoplasm
contain chromosomes
they have ribosomes
control center of the cell, contain the genes.
Nucleus
largest organelle in animal cell
Nucleus
blueprint of life
DNA
Largest organelle in plant
central vacuole
no nuclues
prokaryotic
with nucleus
eukaryotic
protein factories
ribosomes
produce protein needed in cytosol
free ribosomes
for protein in the rough ER
bound ribosomes
powerhouse of the cell, chemical energy conversion, more active the cell more _____ it contains
mitochondria
produce adenosine triphosphate, energy currency of the cell
mitochondria
cellular respiration ( Glycolysis __ ATP, Kreb cycle ___ ATP, Oxidative phosphorylation electron transport chain __ ATP
2
2
34
ATP Per cell respiration
36 to 38 ATP
captures of light energy, site of photosynthesis
choloroplasts
green pigment found in leaves and other green organs of plant
chlorophyll
support, motility, and regulation, network fibers, organizes structure and activities (mechanical support)
Cytoskleton
spindle fibers, separate sister chromatids in anaphase
microtubules
actin filaments, amoeba filaments, contraction of actin, myosin filament
microfilaments
support cell shape
intermediate
microtubules, microfilaments, intermediate
network fibers
suicidal bag, digest bacteria, foreign substance and worn out cell parts
lysosomes
serve as channel which materials are transported
endoplasmic reticulum
contains ribosome- macro molecules to produce protein
rough ER
not contain ribosome- macro molecules to produce lipids
smooth ER
manufacturer, process, package
golgi apparatus
cellulose
plant cell wall
chitins and glucans
fungal cell wall
peptidoglycan
bacteria cell wall
no energy investment, CO2, H20, 02 easily diffuse across plasma memebrane
passive transport
requires energy in the form of
Active transport
group to be transport
bulk transport
going out
exocytosis
coming in
endocytosis
cell drinking, takes in fluid and solute
pinocytosis
cell eating, takes in larger substances, large fats molecule
phagocytosis
tiny microscopic organism, decomposer or chemical recyclers in ecosystem (return mineral and nutrients)
microorganism
eliminate pollutants and converts them in to harmless or useful ones
bioremediation
refers to a kingdom that is used to group archaebacteria and bacteria within it.
monera
Herbert copeland
archaebacteria and eubacteria
Woese and fax
bacteria like
extreme environments
Archaebactreia
no oxygen
methanogens
very salty
halophiles
hot envrinment
thermophiles
tru bacteria
eubacteria
spherical, round, globular
coccus
rod shaped
bacillus
spirilla-spiral
spirillium
comma shaped
vibrio
any eukaryotic organism that is not an animal, land plant, or fungus. polyphyletic grouping of several independent clades that evolved from the last eukaryotic common ancestor.
protoctista or protista\by Haekel
closest relatives of plants (lumot), photosynthetic, 75% major oxygen producer, classified according to pigments
algae
yellow
fucoxanthin
green
chlorophyll
