Osmosis specifically refers to the transport process responsible for the movement of water in and out of
cells.
Among the methods for transporting molecules across a cell membrane, Passive Transport is the only
one that does not require energy.
A hypertonic solution has a higher concentration of dissolved solutes compared to the outside of the
cell, while a hypotonic solution has a lower concentration of dissolved solutes relative to the outside. An
isotonic solution maintains an equal concentration of dissolved solutes in relation to its surroundings.
It is True that during osmosis, the cell either loses or gains water because the solute cannot cross the
membrane.
In an experiment with eggs, the egg loses water when placed in a hypertonic solution, while it gains
water when in a hypotonic solution. When an egg is placed in a saline solution, the salt functions as the
solute and the water acts as the solvent.
If Susan is testing the preference of bumblebees for red flowers, her control group would consist of all
the flowers that are not red. After conducting her study, if her findings reveal that bumblebees spend
80% of their feeding time on red flowers, this indicates that she has found her data supported her
hypothesis, not that she proved all bumblebees prefer red flowers.
Even though she only surveyed 10 plants, her ultimate conclusions should be based on the larger class
data set which provides a more extensive collective analysis.
In distinguishing between monocots and dicots:
- Monocots: one cotyledon; veins parallel; vascular bundles scattered randomly; flowers in multiples of
3; no cambium.
- Dicots: two cotyledons; veins net-like; vascular bundles in a ring; flowers in 4s or 5s; cambium present.
Upon watching the "How to make a Wet Mount" video, it becomes evident that the 0.9% saline solution
(NaCl) used for the cheek cells is isotonic.
,To enhance visibility in the video, a stain known as methylene blue is added to the cells.
In plant cells, you can observe structures such as chloroplasts and the large central vacuole.
It is False that there are gaps between cells in a plant, and also False that the capsule surrounding a
bacterium is smaller than the bacterium itself.
The darkest area in an animal cell is identified as the nucleus.
Bacteria are classified as PROKARYOTE because they LACK a true nucleus. They are always UNICELLULAR.
Plants and animals are called EUKARYOTES because they are composed of cell that always HAVE nucleus
and can be unicellular or MULTICELLULAR. ✔️

electron donor resulting in oxygen gas been given off ✔️Carbondioxide, Water
Which set of reactions of Photosynthesis were we directly manipulating in this experiment?
The Calvin-Benson Cycle or Light Independent
reactions
The Light Reactions ✔️The Light Reactions
When Light Intensity on a plant increases, which of the following are true? Select all that apply)
More ATP is produced
Electrons flow through the thylakoid membrane
into the thylakoid space faster
There is more carbondioxide available for the
Calvin cycle
There is more energy availble to produce
glucose in the Calvin cycle
Photons strike the chlorophyll and other plants
pigment at a faster rate ✔️More ATP is produced. There is more carbondioxide available for the Calvin
Cylce. There is more energy available to produce glucose in the Calvin Cycle. Photons strike the
chlorophyll and other plants pigment at a faster rate.
