The microscope led to the discovery that all living things are made of one or more _
(a)
Which of these describe characteristics of all living things:
select ALL the correct statements
They maintaining internal condictions known as homeostastasis 🥵
They are organized and made of one or more cells 🦠
They must get energy from sunlight or food 🍇🌻
they respond to internal and external stimuli 😎
they reproduce to produce create new organisms 🐣
Which statement is true about the living organisms you viewed under the microscope 🔬 p.11.?
Cheek smear, Pond Water, and Onion
All the cells in each slide looked the same 🔬
All the cells on each slide were the same size 🔬
The cells in each slide had different shapes and sizes 🔬
These organisms are unicellar, meaning they are made of only one cell 🦠.
Bacteria and Amoeba
Humans and other animals
Plants and Fungi
Robert Hooke was the only scientist to discover cells and form the cell theory.
True, he was the one and only
False, other scientists helped discover cells and the cell theory.
Which of the following is NOT a principle of the cell theory.
(p.16 and NB p.47)
All living things are made of one or more cells.
The cell is the smallest most basic unit of life
All new cells come from preexisting cells.
Viruses are cells
Which statements are true about prokaryotic cells - choose 3 true statements- use p.23-24 to help you.
Prokaryotic cells make up the human body
Prokaryotic cells are small and less complete than eukaryotic cells
Bacteria are prokaryotes meaning they are made of prokaryotic cells
Prokaryotic cells do not have a lining or nuclear membrane surrounding their DNA/genetic material
One of your friends puts a piece of onion under a microscope and tells you they think the onion is NOT a living thing. Using what you've learning during lesson one evidence from the microscope image, what evidence can you use to help your friend understand that onions are living by using what you learned in class. Choose the 2 correct responses below.
The microscope shows that the onion is made of cells
Onions grow and develop over time
The onion is eating
Response to stimuli means
responding to the environment
Reproducing to make new organisms
Growth and Development
Cells
Amoebas and paramecium are unicellular because they are made of
Many cells
One cell
After reading page 25 about viruses, viruses.....
Are classified as living because they are made of cells and have all the other same characteristics that living things have
Are classified as a nonliving thing because they are not made of cells and don't grow and develop like othe rliving things.
This picture shows

This picture shows
A prokaryotic cell
A eukaryotic cell
Which statements are true about eukaryotic cells
Eukaryotic cells are larger and more complex than prokaryotic cells
Eukaryotic cells make up humans, animals, fungi, and plants
Eukaryotic cells have a nuclear membrane/lining around their genetic material/DNA
Eukaryotic cells make up bacteria
Which statement is FALSE about eukaryotic cells
Eukaryotic cells are larger and more complex than prokaryotic cells
Eukaryotic cells make up humans, animals, fungi, and plants
Eukaryotic cells have a nuclear membrane/lining around their genetic material/DNA
Bacteria are eukaryotes because they have eukaryotic cells
Which statement is true about prokaryotic cells
Prokaryotes are single celled organisms and include bacteria, paramecium and amoebas.
Prokaryotes are multicellular organisms and include humans, plants, and fungi.
What 3 characteristics do eukaryotic and prokaryotic cells share? p.23-24
Both have a nucleus where genetic material/DNA is found
Both have genetic material/DNA
Both make up living organisms
Both are types of cells
Which TWO living organisms are prokaryotes? p.23-24
Bacteria
Archaea
Humans/Animals
Plants
Which living organisms are prokaryotes and NOT eukaryotes? p.23-24
Bacteria
Protists (some kelp)
Humans/Animals
Plants
Fungi (mushrooms)
When comparing eukaryotic cells to prokaryotic cells, prokaryotic cells
-Choose 3-
are simpler and less complex
are much more complex
are cells that make up unicellular organisms like bacteria
are the cells that make up humans
do not have a nucleus/lining around their DNA
