Explain why unicellular
organisms divide
Unicellular organisms divide to
reproduce
Explain why multicellular
organisms divide
Multicellular organisms divide to
replace damaged cells or to grow
as an organism
What does
specialization mean
and why do
multicellular
organisms have it?
Specialization means the cells have a
specific job/function. Multicellular
organisms have specialization because
the organism is so big, the organs and
organ systems need to work together to
make the organism work efficiently.
Therefore each cell/tissue/organ/organ
system has a specific job or function.
What is the level of cellular
organization?
A group of cells make up tissues
A group of tissues make up an organ
A group of organs make up an organ system
A group of organ systems make up an organism.
The organization of living things is the term to
describe the adaption of cells, organs, or organ
systems for a specific function.
Explain the relationship between
Structure and Function
EXPLAIN!
The shape (structure) of a cell,
organ or organ system depends
on the job (function) it does. The
location, structure and function of
different tissues, organs and
organ systems working together
make the organism work together
efficiently.
What are the 11 organ systems?
1. Muscular
2. Nervous
3. Digestive
4. Excretory
5. Endocrine
6. Digestive
7. Integumentary
8. Skeletal
9. Cardiovascular
10. Respiratory
11. Reproductive

What is the xylem?
•Xylem is the type of tissue in vascular
plants that provides support and
conducts water and nutrients from the
roots.
What is the Phloem?
• Phloem is the tissue that conducts
food in vascular plants.
What’s the function of the
roots?
What organ system in humans
could you compare this to?
• Roots supply plants with water
and dissolved minerals.
Roots hold plants securely in the
soil.
Roots store surplus food made
during photosynthesis
Roots could be compared to the
skeletal system of humans.
What organ system in the human
is like the xylem and phloem in a
plant?
The xylem is like the
cardiovascular system in the
human. The phloem would be
more like the digestive system
in a human.
What is the function of
the stem?
What organ system in
the human is like the
stem in a plant?
The function of the stem is to
provide support. This could be
compared to the skeletal system
of humans.
What phase change is happening
at red arrow when heat is added?
Melting – going from a solid to a
liquid
What phase change is happening at
red arrow when heat is taken away?
Condensation – going from a gas to
a liquid
Why does the temperature remain the
same as heat is added at the red arrow?
The reaction requires energy for a
phase change to happen.
What organ system in a human is
like the flower of a plant?
The reproductive system
What do leaves do for a plant?
Leaves collect the sunlight and
the chlorophyll in the leaves
creates the food for the plant.
