cell to organism unit 2.4
- In a complex organism, there are
many more cells than there are
tissues, many more tissues than
organs, and many more organs than
systems
- tissues
- tissues
- In the human body there are
four types of tissues: *elepthial
tissue *connective tissue
*muscle tissue *nerve tissue
- epithelial tissue is made up of cells
that form surfaces of other organs
.your skin has an outer layer of
epithelial tissue called the epidermis.
epithelial tissue also lines the
surface of the digestive system,
repiratory system, reproductive
system and the mouth
- connective tissue holds and
supports other tissue in the
body e.g. fat, bones, cartilage,
ligament and tendon.
- tendon
- tendon
- muscle tissue is a specialsised tissue that can
contract, becoming shorter and fatter. biceps
are themuscles that contract to pull your
arm up, triceps contract to pull the arm back
down as muscles cant expand.
- biceps & triceps
- biceps & triceps
- nerve tissue can send
electrical signals around
the body. the electrical
signals are managed in
the brain by nerve tissue
and passed down the
spinal cord to the body.
thousands of nerve cells
are grouped together to
form your nerve.
- epithelial tissue is made up of cells
that form surfaces of other organs
.your skin has an outer layer of
epithelial tissue called the epidermis.
epithelial tissue also lines the
surface of the digestive system,
repiratory system, reproductive
system and the mouth
- organs are structures that contain atleast
two different types of tissues that work
together to complete a task e.g. stomach,
liver, heart.
- heart
- heart
- organs cant work independently so they
are organised so they can work
together too complete a task e.g.
digestive system, reproductive system,
respiratory system, nervous system
and skeletal system.
- organ systems
- organ systems
- there are two types of vascular
tissues
- XYLEM carries water from the
roots. they are long thin tubes
with strong walls to help
support the plant.
- xylem
- xylem
- PHLOEM carries
glucose from the
leaves to all other
plant parts.
- phloem
- phloem
- XYLEM carries water from the
roots. they are long thin tubes
with strong walls to help
support the plant.
- the main organs of a plant are its roots, stem
and leaves. these organs work together to bring
together the raw materials required for
photosynthesis.
- leaf
- leaf
