cells function to
react to environment
size of an organism depends on
the number of cells it has
golgi bodies have
proteins that eventually break off into secretory vesicles
by Lauren Huhn
mod four
cells function to
obtain oxygen
rough ER
ribosomes attached to its surface so proteins formed can enter into the cavities of the ER
cells function to
rid the cells of waste
secretory vesicles function to
control the release of energy;
lysosomes
"suicide sacs" arise from the Golgi bodies membranes bordered structures ; functions to breakdown large molecules from worn out or damaged cell structures; in animal cells
endoplasmic reticulum
network of interconnected tubes and membranes enclosing fluid filled cavities and is attached to the nuclear memb. and the plasma memb.
hydrophilic
glycerol "water loving" and is the top circle part of the lipids of the bilayer
cells functions to
is involved in energy transformation (cellular respiration)
secretory vesicles are
involved in cellulose production in plants ; numerous in cells of glands; involved in lysosome formation
Schwann
German zoologist
cells function to
obtain food for energy
cells function to
synthesize new cellular material
cells function to
obtain necessary materials
cells function to
regulate water balance
cytosol
protein rich semi-fluid substance located outside the nucleus and inside the cell memb.
secretory vesicles
can fuse to the cell memb. and dump its contents out of the cell
cell membrane contains... and is called...
lipid, protein, cholesterol and carb molecules and is called "fluid mosaic model"
the er functions to
support other organelles in cell; prepare proteins for secretion; transport material inside cell
nucleolus
composed of chromatin (DNA) and protein and produces ribosomes
cyotosol is composed of
70% water and 30% protein, fats, and carbs
Virchow
German physician
nuclear membrane
two membranes form a boundary around the nucleus; pores in membrane allow certain molecules to enter and leave
cell membrane or plasma membrane
holds cellular contents together and allows certain substances to enter and leave the cell
hydrophobic
fatty acid "fear of water" stick part of the lipids of the bilayer
outside of lipid bilayer is
the side with sugar sticking out
centrioles
often lie close to the nucleus; in animal cells
Schleiden
German botanist
ribosomes
"protein factory" dense granules that synthesize proteins for secretion
cells function to
reproduce
ribosomes that are not attached to the ER
will produce proteins that will be used in the cell
cytoplasm
all organelles and materials within a cell located between the plasma membrane and the nucleus
cristae
folded inner membrane of mitochondria
chromosomes
composed of dna and protein and contains hereditary info
ribosomes attached to the ER
produce proteins that will be released from the cell and used by other cells
golgi bodies
temporary storage place for proteins formed by ribosomes; involved in protein modification to help make it function; collects, packages, distributes molecules made in one location of the cell and used in another
nucleus
the control center most activity inside cell is caused or controlled by the nucleus
each lipid has a ......
phosphate attached to it
smooth ER
er without ribosomes; store enzymes and chemicals
vacuoles
"storage room"; stores materials such as water, salts, proteins, and carbs
cristae functions to
increase the surface area so more enzymes can attach and convert glucose to energy; extreme cold can disorganize mitochondria-enzymes sewll and fall off the cristae and can no longer convert energy
