Cell in its
Environment
magnification = bigger, resolution = clarity
What is the difference
between resolution
and magnification?
Row 1, Col 1
Cell wall only in plant, membrane in all
How are the cell membrane
and cell wall different?
1,2
Speed up chemical reactions
What do enzymes do that is
important for our bodies?
1,3
osmosis
Which term refers to the diffusion
of water molecules through a
selectively permeable membrane?
1,4
function
Cells are the basic
unit of structure and
______________ in living
things.
2,1
ribosomes
Which organelle produces proteins?
2,2
starches
Sugar molecules can combine
with one another to form
large molecules called _____.
2,3
High concentration, Low concentration
Diffusion is the movement of
molecules from areas of
_______________ to
__________________.
2,4
Other cells
According to the cell
theory, where do
all cells come from?
3,1
Mitochondria = turns food to energy, Chloroplast = turns
sunlight energy to food energy
How are mitochondria
and chloroplasts different?
3,2
Make up cell membrane, store energy
What is the function of lipids?
3,3
Active Transport
The movement of materials
across the cell membrane
when energy is required.
3,4
200x
If a compound microscope
has a 10x lens in its
eyepiece and a 20x lens
in its nosepiece, its total
magnification is _____.
4,1
Repackage and send out proteins to parts of the cell
What is the function of
the golgi apparatus?
4,2
Foods with a lot of lipids. (more energy)
What types of foods should
a bear eat before hibernation?
Why?
4,3
Molecules will be moving faster
Why would raising the
temperature make diffusion
happen faster?
4,4
Robert Hooke
Who first observed cells?
5,1
Tissue, organism
Cells  _____  Organ 
Organ system  _______
5,2
Nucleic acids; DNA
______ are the chemical compounds
that contain the instructions
that cells need to carry out
all the functions of life.
5,3
It chooses what can enter/exit the cell
The cell membrane is
selectively permeable. What
does that mean?
