Movement
Respiration
Sensitivity
Growth
Reproduction
Excretion
Nutrition
Movement
The ability of organisms to
move
, a change of
position
Movement
Move from place to place
Move parts of themselves
Reproduction
Organisms can make more living things like themselves
Things plants do to reproduce that animals do not
Make
seeds
Make
fruit
Use
insects
for pollination
Sensitivity
The ability to
detect
and respond to changes in the
internal
and external environment
Sensitivity
Changes in
temperature
Growth
Living things
increasing
in size
How trees grow
They continue to
grow
How humans grow
They stop
growing
after a while
Respiration
A set of
chemical
reactions that release
energy
for metabolism
How fish get
oxygen
They get it from
water
How humans get
oxygen
They get it from
air
Excretion
The removal of
waste
products of
metabolism
, substances in excess of requirements
Nutrition
Taking in of materials for
energy
, growth and
development
Systems of the human body
Digestive
system
Circulatory
system
Nervous
system
Urinary
system
Digestive system
1. esophagus (gullet)
2.
Stomach
(breaks down food)
3.
Small intestine
(breaks up food and absorbs it)
4.
Large intestine
(removes water from unwanted food)
5.
Liver
(makes, stores and destroys substances)
Circulatory system
1.
Heart
(pumps
blood
)
2. Blood
vessels
3.
Blood
Nervous system
1.
Brain
2.
Spinal chords
3.
Cranial nerves
4.
Spinal nerves
Urinary system
1.
Bladder
(stores urine)
2.
Kidneys
(clean blood and produce urine)
3.
Rectum
(stores waste materials)
Heart tissue
Whiter parts are
fat
, reddish parts are
muscle
Fat
tissue helps to
protect
heart
Muscle tissue pumps
blood
Root tissues
They have hairs on the outside to help the roots take water out of the soil quickly
Xylem tissues in carrots
They carry water up from the roots through the carrot and on into the rest of the plant
Leaf
Traps sunlight to make food for the plant
Stem
Carries substances around the plant and supports the leaves and flowers
Root
Holds the plant in place
Takes in
water
and small substances from the
soil
a microscope is used to magnify a specimen to see
structures
which
cannot
be seen with the naked eye
stage
platform
to place the
slide
total magnification=
magnification
of
eyepiece lens
x magnification of objective lens
eyepiece lens
to look at the
specimen
objective lens
for
greater magnification
coarse focus
knob
to bring the specimen to focus
fine focusing wheel
helps the image focus
bladder
stores
urine
kidneys
clean the
blood
and produce
urine
to excrete wastes
liver
makes and stores some
substances
, and
destroys
other substances
lungs
get
oxygen
into the blood for respiration, and
excrete carbon dioxide
large intestine
removes
water
from
unwanted
food
small intestine
breaks up
food
and absorbs it, to provide
nutrition
for the body
