lacks organelles beyond ribosomes
Compared with a eukaryotic cell , a prokaryotic cell
not allowing them to produce proteins
There is an antibiotic called streptomycin that inhibits the function of bacterial ribosomes . Consequently as the bacterial cells die the person taking the antibiotics gets better. In other words, the antibiotic destroys bacteria by
False
TRUE OR FALSE : Plant cells have walls but do not have plasma membranes .
True
TRUE OR FALSE : The hydrophilic parts of the plasma membrane are oriented towards both the outside of the cell and the cytoplasm .
True
TRUE OR FALSE: Proteins within the extracellular matrix play a role in communicating between the matrix and the cytoskeleton.
establishing the identity of the cell

produce ATP
Both plants and animals need mitochondria to
separate the DNA from other activities that occur in the cytoplasm
Eukaryotic cells have DNA enclosed in a double membrane called the nucleus . The nucleus functions to
plasma membrane - outermost barrier of a plant cell

actin filaments, myosin, microtubles, kinesin
Which of the following is a type of intracellular protein?
are involved in energy conversions ; are found in nearly all eukaryotic cells
Mitochondria and chloroplasts are similar in that they both ________, but are different in that mitochondria, but not chloroplasts, ________.
both plant cells and animal cells
Mitochondria are found in
plasmodesmata
Plant cells are connected to one another by
connect the cytoplasm of one cell with that of another

bind to signal proteins from other parts of the body
Receptor proteins allow a cell to
pass through the membrane via proteins
Since the plasma membrane blocks the passage of all but a few molecules with specific traits , it is necessary for other molecules to
