Levels of organization
SWBAT determine the correct order of the levels of organization for structure and function, including
cells
tissues
organs
organ systems
whole organisms
ecosystemsSlide2
Over the past few weeks…
We learned cells
are the building blocks of life
We have discussed different types of cells and how they function
Now, we will see the next step in “building” organisms!
The next few weeks, we will discuss all the different types of body systems that humans (and other organisms) have that allow for life to occurSlide3
Levels of Organization Slide4
Organization of the Body
We can compare organization of a book to the body
The book = The human body
A Chapter=
An organ
system
A Paragraph=
The organs
The words=
The tissues
The letters= the cellsSlide5
Cells
Different body tissues and organs are made up of different kinds of cells.
The
cells in similar tissues and organs in other animals are similar to those in human beings but differ somewhat from cells found in plants.
Brain Cell
Cardiac (heart) muscle cell
Slide6
Cells
The smallest part of living things
All living things must be made up of cells
Examples: brain cells, cardiac cells, skin cells, brain cells, muscle cells…
Brain Cell
Cardiac (heart) muscle cell
Slide7
Tissue
Groups
of
similar cells work to
form a tissue, such as
muscle
tissue. Slide8
Organ
Different tissues are in turn grouped together to form larger functional units, called organs.
Example: Heart, brain, lungs, etc. Slide9
Organ System
Organs group together to form
systems, such as the circulatory system, which pumps blood through the heart
The
circulatory system is made up of organs - the heart, veins, arteries, etc. Slide10
Organism
All organ systems
group together to form
organisms.
Example:
humansSlide11
Ecosystem – a community of living organisms
All
of the
organisms in an area make up the ecosystem of that area
Example: Amazon Rainforest in BrazilSlide12
Cell Specialization
Each type of cell, tissue, organ, organ system
has a distinct structure and functions
that serve the organism as a whole.
Specialized cells perform specialized functions in multi-cellular organisms Slide13

3 Important Facts
Complete the bottom box on your notes page to sum up what you think were the most important parts of today’s lessonSlide15
Check For understanding
Dry-erase boards Slide16
Partner Practice
You will answer questions with your partner
After I read the question, you will discuss at noise level 1
Do NOT raise your boards until I say soSlide17
???????????
Every living organism is made of one or
more…
a)cells
b)organs
.
c) organ
systems.
d) tissues
.Slide18
?????????????
One reason that multicellular organisms are more complex than unicellular organisms is that similar cells are grouped together to perform a specific task. When cells are arranged this way, what do they form?
a)tissues
b)organelles
c)organs
d)organ
systemsSlide19
???????????
Which of the following is organized from simplest to most complex
?
a
. cells->organs->organ systems->tissues->the organism
b
. cells->tissues->organs->organ systems->the
organism
c
. the organism->organ systems->organs->tissues->cells
d
. tissues->cells->organs->organ systems->the organismSlide20
????????
Which is larger and more complex: cardiac muscle tissue or the circulatory system?Slide21
?????????
Which is less complex: a brain cell or a brain tissue?Slide22
????????
What does a group of tissues create?Slide23
??????????
What does a group of organs create?Slide24
?????????????
What does a group of organ systems create?Slide25
??????????
What is an example of a specialized cell?Slide26
??????????
Are the specialized cells we just talked about prokaryotes or eukaryotes?
