Osmosis is the special transport process for the movement of ______ in and out of the cells.
Oxygen
Energy
Sugar
Water - correct answer ✔✔Water
Which of the following transportation of molecules across a cells membrane does NOT require
energy?
Active transport
Exocytosis
Endocytosis
Passive Transport - correct answer ✔✔Passive transport
Hypertonic - correct answer ✔✔Has a high concentration of dissolved solute relative to the
outside of the cell
Hypotonic - correct answer ✔✔Has a low concentration of dissolved solute relative to the
outside of the cell
Isotonic - correct answer ✔✔Has an equal concentration of dissolved solute relative to its
surroundings
,T/F When osmosis occurs the cell loses or gains water because the solute cannot cross the
membrane. - correct answer ✔✔True
In your egg experiment, the egg lost water through its membrane when it was placed in a/an
________ solution and your egg gained water through its membrane when it was in a/an
_______ solution - correct answer ✔✔Hypertonic, Hypotonic
When an egg is placed in a high salt solution, the salt is known as the _____ and the water is
called the ______ . - correct answer ✔✔Solute, Solvent
If Susan is specifically testing the hypothesis that bumblebees prefer red flowers, then what is
her control?
The different types of red flowers
Different species of plants
All the different types and colors of flowers
All flowers that are not red - correct answer ✔✔All the flowers that are not red
Susan is studying which flowers bumblebees select in a patch of garden flowers. At the end of
the study the results show that bumblebees spend 80% of their time feeding from red flowers.
Thus, Susan
Supported her theory
Showed bumblebees only feed from red
flowers
Found her data supported her hypothesis
Proved all bumblebees prefer red flowers - correct answer ✔✔Found her data supported her
hypothesis
, You only had to survey 10 plants, but the whole class will end up with a much larger collective
data set. Which data set is the one upon which you should base your ultimate conclusion about
the hypothesis?
My data set with 10 plants
The larger class data set. - correct answer ✔✔The larger class data set
Monocot vs Dicot - correct answer ✔✔Monocot= one cotyledon; veins parallel; vascular
bundles scattered randomly; flower in multiples of 3; no cambium
Dicot= 2 cotyledons; veins netlike, vascular bundles in a ring; flower in 4 or 5; cambium present
KNOW EXAMPLES OF EACH
After watching the "How to make a Wet Mount" video
What type of solution is the 0.9% saline (NaCl) she puts her cheek cells in?
Isotonic
Hypotonic
Hypertonic - correct answer ✔✔Isotonic
In the video: What does she do to the cells, to make them more easily visible?
Turns on the light
Adds a stain called methylene blue
