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

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.

Would you choose to be cryogenically preserved if the

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.
