Learning Objectives I know that cells are differentiated in
multi- celled organisms and each cell type has a different job to
do. I can explain how the shape of a certain cell type helps it to
perform its job. I can explain the difference between tissues,
organs and organ systems.
Slide 3
Living Systems = Each part of an organism has parts that work
together in order to perform a job (in order to stay alive). The
parts are called structures, and the kinds of work they do are
called functions.
Slide 4
Parts of a Living System All living systems are made up of
cells, the basic unit of life. Many cells working together at the
same job form tissues. Different tissues work together to form
organs. Organs work together to form organ systems. Organ systems
work together in the body or larger organism.
Slide 5
The Structure of Life Each organism has unique structures
suited to its particular way of life. Different organisms may use
similar and different structures to do the same job.
Slide 6
Structure and Function For example, tiny hair-like cilia
surround the microscopic organism known as a paramecium. The cilia
move back-and-forth like the oars of a boat to move the paramecium
through water. Can you think of an organism that has similar
methods of movement?.

CELLS Cells have different sizes and shapes, based on their
JOBCells have different sizes and shapes, based on their JOB Some
can be very SMALL and some can be very LARGESome can be very SMALL
and some can be very LARGE

kind of cells are humans made of: prokaryotic or eukaryotic? 2.
Which organelle gives plant cells their green color? 3. How long
are the LONGEST nerve cells?

TISSUES Tissues are composed of many cells working together to
do the same function.Tissues are composed of many cells working

your skin Connectiv e Fills in spaces and connects other tissues
together; supports, protects, nourishes, and insulates organs.

ORGANS Organs are structures that are composed of two or more
different types of tissues.Organs are structures that are composed
of two or more different types of tissues. They have specific
functions and have recognizable shapes.They have specific functions
and have recognizable shapes. Examples of organs are: Stomach,
Liver, Heart, Lungs, and BrainExamples of organs are: Stomach,
Liver, Heart, Lungs, and Brain
