Chapter 4 A Tour Of The Cell Flashcards
buffer
intermediary to balance a solution
what is a cell?
basic unit of life
smallest cell?
mycoplasma mycoides
prokaryotic cells
contain:
cell wall
membrane
cytoplasm
chromosome
flagella
what is the flagella?
a propellor that moves nutrients in prokaryotes
what makes up eukaryotic cells?
nucleus
mitochondria
cytoskeleton
Golgi apparatus
ER
chloroplasts
vacuoles
how do you get more surface area in a cell?
more folded membranes creates more sheets
what is the cytosol made up?
water, ions, nutrients, 20% protein, macromolecules
nucleus
command center of the cells that stores information (DNA)
membranes
transport network of tubes
the nucleus is packed of
chromosomes
what are chromosomes made of?
DNA and protein
mRNA
transports information into ribosome while exiting the nucleus
protein synthesis
read code from genes by mRNA and is processed into antibodies
endomembrane
exports macromolecules to everywhere in the cell
vesicles Join to the
Golgi apparatus
Golgi apparatus
ships proteins
Bucky dome
a large center of the protein ( vesicle)
motor proteins
move cargos of proteins by microtubules
energy organelles
mitochondria and chloroplasts
cytoskeleton
gives support, movement, organization, transportation and cell division
central vacuole
biggest plant organelle that stores water proteins and nutrients
macromolecular assembly
ribosomes
ribosomes are bigger in _ and smaller in _
eukaryotes and prokaryotes
does bacteria have a cytoskeleton?
yes it does since the cytoskeleton can help cell division, this helps bacteria to divide.
flagella in eukaryotes
move side to side instead of a circular movement
membrane polarity
non polar body and polar heads
is the cell wall just a wall?
no, its a mesh that prevents the cell from bursting.
