Unit 5 BIO 101
The main structural component of a plant cell wall is
cellulose
All cells have some characteristics in common; both prokaryotic and eukaryotic cells have
cytoplasm, a plasma membrane, and DNA.
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.
Where do the vesicles that are being made for secretion from the cell become modified and packaged?
Golgi apparatus
Which of the following organelles would form a membrane-bound package, also known as a vesicle?
Golgi apparatus
Chromosomes are made from
NOT CELL RECOGNITION PROTEINS
Which of the following organelles is not surrounded by a membrane?
NOT chloroplast
Plant cells have plasmodesmata that
NOT resemble the cytoskeleton of animal cells
Which of the following is an incorrect match of molecule to the location where it is principally used?
glucose - lysosome
A stack of thylakoids inside a chloroplast are known as what?
granum
What does the folding of the mitochondrial inner membrane provide?
greater surface area for ATP production
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.
Bacteria hold their DNA is region inside of their outer membrane. What is this region called?
nucleoid
Which feature is found in all cells?
plasma membrane composed of phospholipids
Plant cells can communicate with each other using what structure?
plasmodesmata
Both plants and animals need mitochondria to
produce ATP.
Which of the following is the correct sequence for an altered protein that is secreted from the cell?
rough endoplasmic reticulum - Golgi apparatus - plasma membrane
Which of the following is an incorrect match?
smooth endoplasmic reticulum - storage of water
Eukaryotic cells move their organelles using
the cytoskeleton.
