Definition
Both C and D are true.
Term
Proteins are present in
Definition
both plant and animal cells.
Term
Plants store glucose in the form of
Definition
starch.
Term
When comparing Elodea cells with cheek cells, which of the following statements is true?
Definition
Elodea cells have a cell wall, a central vacuole, and chloroplasts, but cheek cells do not have these structures.
Term
An organelle that is present in Elodea cells, but is not present in onion cells is the
Definition
chloroplasts.
Term
A plant cell organelle that stores dissolved material is the
Definition
vacuole.
Term
The flowing motion of the cytoplasm, within the Elodea cells, which cause the organelles (i.e., chloroplasts) to move is known as cytoplasmic streaming or
Definition
cyclosis.
Term
The center of most plant cells, such as Elodea, appears to be empty. This is due to the presence of the
Definition
a large central vacuole .
Term
Two cellular structures that are present in a plant cell, but are not present in an animal cell are the _______ and the _________.
Definition
chloroplasts; cell wall
Term

Term
Is the cytoplasm in a red blood cell (hypertonic, hypotonic, or isotonic) to distilled water?
Definition
hypertonic
Term
Watson and Crick worked on the 3-D shape of the DNA molecule at
Definition
Cavendish Laboratory in Cambridge, England.
Term
Is the cytoplasm in a red blood cell (hypertonic, hypotonic, or isotonic)
to a 5% NaCl solution?
Definition
hypotonic
Term
Will there be any movement of water molecules across the membrane on the isotonic slide?
Definition
Yes
Term
What is your reasoning for the answer you chose in this question; On the slide with the Elodea and the hypertonic solution, did the entire cell shrink or only the cell content?
Definition
The movement of water out of the central vacuole caused the plasma (cell) membrane to pull away from the cell wall and shrink the cell's content inward, however, the rigid cell wall remained intact.
Term
