Biology 101 Final
A cell being observed under a microscope has a cell wall, plasma membrane, ribosomes, and chromosomal material that is not found in a nucleus. Based on this information, the cell could be a
bacterial cell.
Without receptor proteins, a cell would not be able to
bind to signal proteins from other parts of the body.
Mitochondria are found in
both plant cells and animal cells.
The main structural component of a plant cell wall is
cellulose.
Chromosomes are made from
condensed chromatin.
Plant cells have plasmodesmata that
connect the cytoplasm of one cell with that of another.
All cells have some characteristics in common; both prokaryotic and eukaryotic cells have
cytoplasm, a plasma membrane, and DNA.
Without tight junctions in certain tissues,
fluids may leak out past the barrier the junction would create.
A stack of thylakoids inside a chloroplast are known as what?
granum.
Carrie would like to observe the cilia on the surface of a live paramecium—a single-celled organism. The best device to do this would be a
light microscope.
In bacterial cells and plant cells, cell walls function in
maintaining cell shape.
Which organelle is required for producing ATP for cellular work?
mitochondria
Bacteria hold their DNA is region inside of their outer membrane. What is this region called?
nucleoid
Which of the following organelles would form a membrane-bound package, also known as a vesicle?
Golgi apparatus
What must materials pass through to enter or leave a cell?
plasma membrane
Which feature is found in all cells?
plasma membrane composed of phospholipids
Plant cells can communicate with each other using what structure?
plasmodesmata
Which of the following organelles is not surrounded by a membrane?
