A biologist diluted a blood sample with distilled water. While observing the sample under a microscope, she noted
that the red blood cells burst. This bursting is most likely the result of which process?
a. staining
b. ingestion
c. osmosis
d. active transport
What is osmosis?
100
The basic unit of structure and function in protists (single-celled eukaryotes) and monerans (single-celled prokaryotes).
What is a cell?
200
Chloroplasts, cell wall, mitochondria
What is eukaryote
200
Releases energy for metabolic activity in a nerve cell
What is mitochondrion?
200
This organelle would be present in the cells of a mouse, but not in the cells of a bean plant.
What are centrioles?
200
The process of osmosis is best illustrated by the movement of
A. water into root hair cells
B. oxygen into red blood cells
C. carbon dioxide through stomates
D. glucose through phloem
What is water into root hair cells?
200
A well-accepted body of knowledge about a topic. This is the result of the observations and of many scientists.
What is a theory?
300
Does not have a nucleus.
What is prokaryote?
300
"tail" used for movement
What is a flagellum?
300
Damage to this structure will most directly disrupt water balance within a single-celled organism.
What is the cell membrane?
300
Which process requires the expenditure of cellular energy?
A. passive transport
B. active transport
C. osmosis
D. diffusion
What is active transport?
300
Specialized internal structures that help cells maintain homeostasis.
What are organelles?
400
Plants, animals. Has a nucleus and other membrane-bound organelles. Complex.
What is eukaryote?
400
Stores genetic information (in eukaryotes),
What is the nucleus?
400
Which structure, composed mainly of proteins and lipids, aids in maintaining homeostasis in a cell?
What is the cell membrane?
400
What process must a cell use to move particles from an area of low concentration to an area of high concentration?
What is active transport?
400
The energy molecule used by ALL cells;
What is ATP?
500
DNA is floating in the cytoplasm.
What is a prokaryote?
500
Muscle cells use more energy than skin cells. What organelle do muscle cells have more of than skin cells?
What are mitochondria?
500
Only in plant cells - converts energy from the sun into glucose for the cell to use.
What is a chloroplast?
500
You put a red blood cell in distilled water. What will likely happen to the cell?
What is it will swell and then burst apart?
500
When preparing a wet mount slide, this structure is placed at an angle to prevent trapping bubbles.
