JQ: What can the appearance of the animal and plant cells below tell you about their functional differences? Explain. (Anatomy & Physiology)
Human Cheek Cells 400x Elodea plant Cells 400x
Tissues = group of similar cells working
together.
Lines and protects body
surfaces. Example: Skin & Lining of Organs
Connects, supports and
insulates body. Example: Blood,
fat, bone.
Adipose Tissue
Contracts & relaxes to produce
movement.Example: walls of intestines, heartCarries info. to all parts of the
body.Example: neurons

JQ: What does it mean to be
independent? Are you
independent? Explain.
Humans are made up of trillion's of cells that have special jobs in order to work
together. This way they have a better
chance of surviving.
Our cells can’t survive
independently
What is a cell?The basic unit of
structure and function for all living
things!
A theory is a well tested hypothesis that has not been proven incorrect to date.
What is a theory?
1.All living things are made
from one or more cells.2.Cells are the basic unit of
structure and function in living things. (Smallest form of life!)
3.New cells come from existing cells.
What is cell theory?

1. Prokaryotic Cell – cells that lack a membrane bound nucleus. Example: Bacteria and archaea
What types of cells exist?
2. Eukaryotic Cell – a cell that contains a membrane bound nucleus & many specialized structures called organelles.
“Tiny organs” - specialized structures
found within a cell.
What are organelles?
Single Celled – 1 cell (ex. Ameoba, Paramecium)
Multicellular –many specialized cells working together (plants and animals)
Types of Eukaryotic cells
Plant Cell
Animal Cell

Avatar’s skin blue? Explain.
JQ: Would you rather have the ability to shrink to the size of a pin head or grow to the size of an oak tree?
Explain.

JQ: When scientists first attempted to make an
avatar they were unsuccessful. After further
inspection they realized that a virus snuck past its
immune system and into its cells. Once in the cell it took over and destroyed the cells. Scientists think
that the avatar’s cells were missing an organelle.
Which organelle was most likely missing from the
avatar’s cells?

Now What?You’ve learn about how
organisms interact on this planet, and the damage that humans are causing
to the balance of life. We’ve even discussed some solutions to the
problem.
You’ve also learned about how organisms are put together, from cells to
organ systems.

technology was available? Explain.
JQ: If you are going to build an Avatar you will need to gather some DNA from a Na’vi and a human. Getting the DNA from a human is easy, but how would you go about getting it from a Na’vi? Explain.
