CHARACTERISTICS OF LIFE
humans have systems organs thatwork
of together
cells make up tissues
+issues make up organs
organs make up organ systems
MRS. GREN
movement:an action by an organism (or part) causing
change of position or place
respiration:the chemical reactions in cells that
break down
nutrient
molecules and release energy for metabolism
sensitivity:the ability
to or
detect sense stimuliin the internal
or external environment and to
make appropriate responses.
growth: apermanant increase of
Size
excretion:removal from organisms of the waste products
metabolism, toxic materials and substances
of
nutrition:taking in of materials for energy, growth and
development
GLOSSARY
biome:a community of plants and animals thathave
similar environments (characteristics)
population:a group ofindividuals of the same species living
within a given area
ecosystem:a community
of
living organisms in conjunction
with thenon-living of
components their environment.
community:a interacting group ofvarious species in a
common location
system:a complex biologically
network of beings.

, CELL STRUCTURE
GLOSSARY
nucleus:controls actions and reactions of cell
cell membrane: controls whatgoes ind of the cell
out
cell cytoplasm:where chemical reactions take place
cell wall:made of cellouse, provides support
chloroplasts:absorbs light, allows take place
photosynthesis to
vacuoles:contains dissolved sugar (stores them),gives cell shape
MAGNIFICATION
magnification length of objectin the image/actual

magnification has no units.
DIFFUSION
diffusion is the hetmovement
ofparticles from a region
length
object of higher a
concentration to region of lower concentration
down a concentration gradientas a resultof random movement
magni-actual
Size
factors affecting rate diffusion
of
fication
surface area diffusion
the LP

temperature 4 distance
object
↳ concentration gradient
partially permeable membrane
OSMOSIS is a membrane that controls
osmosis is the of water
movement molecules from whatgoes in and out of
cells
a region ofhigher water potential (dilute solution) to
a region of lower water potential (concentrated solution)
through a
partially permeable membrane
, HUMAN TEETH
type of footh number
incisor 8
canine
Pre-molar I
molar 12
PARTS OFTOOTH
pulp carity:formation and nutrition of dentin
crown:part of tooth above gum
provide the sensation of heat, cold and pain
nerve:to
bite things
enamel:for protection, enables you to
jaw and acts as
cement:helps attach rootto a shock absorber
root:to anchor the tooth in position
dental pulp:supply food & oxygen to the living cells of tooth
pulp:soft tissue surrounding the bone
dentine:reinforces the tooths enamel and helps support
the structure of the tooth
TYPES OFTEETH
incisors:chisel shaped teeth atthe front of the mouth.
they are used tocut pieces from food
canines:pointed both sides of the incisors.
teeth on
they are used for gripping and tearing
premolars and molars:flattopped teeth in the Cheeks.
they have points or cusps. upper and lower cusps fittogether.
they are used for grinding and crushing food
TOOTH DECAY
↳ as tooth is acid produced by plaque bacteria, the
exposed to
enamel melts. Gradually, acid wears down a pathway for bacteria
the dentin. If the damage extends beyond dentin, itwill cause
into
pain as the nerves become exposed.
your tooth will then have to be removed or filled.
