Diffusion
Movement of solids, liquids or gasses
from areas of high concentration to
areas of low concentration.
Osmosis
Water movement
across a membrane
Passive Transport
Small molecules moving through small passageways in the
membrane with no energy needed.
Active Transport
Movement of materials across the
membrane with the use of energy,
usually needing specialized
passageways
Endocytosis &
Exocytosis
Particle movement
IN and OUT of the
cell.
Word formula for
Photosynthesis
Carbon dioxide +
water
=
glucose + oxygen.
Word formula for
respiration
Glucose + Oxygen
=
Carbon Dioxide, Water
and energy
Name 2 extra ideas
related to Photosynthesis
that make the process complete
(beyond the formula)
Sunlight and Chlorophyll are
necessary
Name 2 things
needed for
respiration to occur
(beyond the
formula)
A living cell with mitochondria
Daily Double
Write the 2
chemical formulas
CO2 + H2O = C6H12O6 + O2
Is photosynthesis
C6H12O6 + O2 = CO2 + H2O + energy
Is respiration
fermentation
Cellular
respiration with
low oxygen
Aerobic respiration
Oxygen is available
for complete
breakdown of the
sugar/energy
Mitochondria are
found in these cells
in greatest
numbers (animals)
Where energy is
needed most often
– muscles for
example
90% of the cell
cycle is what action
The cell is carrying
out normal
functions of
metabolism- life
What is Mitosis?
Cell divisioncreating 2 cells
from 1
What is the main
action in prophase?
replication of the
DNA, replication of
centrioles, dissolving
the nuclear
membrane
When and how is
the word
“equator” used in
the cell cycle?
A line up of
replicated DNA
pairs forms in the
middle of the cell
in metaphase
When and where
do the chromatids
“migrate”?
Sister chromatids separate
in Anaphase and migrate
to the “poles”
What is the proper
name for the
original cell before
mitosis?
Parent Cell
What is the proper
name for the two
cells resulting from
mitosis?
Daughter cells
What is
cytokenesis?
At the end of
mitosis, the
cytoplasm splits in
two.
The cell membrane
pinches in to divide
what kind of cells?
Animal cells
(and protist cells)
A cell plate forms
in what kind of
cell?
Plant cells
(and algae, fungus)
Compare the
number of DNA
molecules in the
beginning cell to
the resulting 2 cells
Same number of
DNA molecules
What would
happen if
cytokenesis
happened without
mitosis?
A division of the DNA
would be uneven and
resulting cells would
either die, or be severely
mutated
Make your wager
Homologous
Chromosomes
Another name for
sister chromatids,
the replicated pairs
of prophase.
