Unicellular vs Multicellular
Unicellular organisms are made of how many cells?
One
A chair and a pencil are examples of these.
Non-living
These are tiny “parts” inside a cell that each have a specific job to help the cell survive.
Cell Organelles
This organelle surrounds the cell and controls what goes in and out.
Cell Membrane
What are cells called that have a specific job to do in an organism?
Specialized Cells
This type of organism is made of many cells that work together.
Multicellular
Give an example of 2 living things.
dog, human, ...
This is the control center of the cell.
The nucleus
Plant cells have this extra layer outside the cell membrane for support and protection.
Cell Wall
What type of cell covers and protects the outside of your body?
Skin cell
Bacteria and amoebas are examples of this type of organism.
Unicellular
This is one thing all living organisms are made of that nonliving things are not.
Cells
This organelle in plant cells captures sunlight to make food through photosynthesis.
Chloroplast
This organelle is called the “powerhouse” of the cell because it makes energy.
Mitochondria
Explain why multicellular organisms have specialized cells.
Different tasks need to be done at the same time for the organism to survive
In this type of organism, different cells have different jobs, such as muscle cells or nerve cells.
Multicellular
A seed that is not growing yet but can grow into a plant is considered…
Living
Which two organelles do PLANTS only have?
Chloroplast and cell wall
Why is a cell membrane like a drawbridge in a castle?
Because decides which things can come in and out of the cell.
This type of cell carries oxygen throughout the body.
Red blood cells
This is one major difference between unicellular and multicellular organisms: the number of ______ they have.
cells
Fire can grow and use energy, but it is not considered living because...
Could be:
- does not have cells
- cannot reproduce
- does not have DNA
Why is the nucleus like a music director?
Because they tells the group of musicians what to do and when to do it, just like nucleus tells when and what to do in the cell.
Why would a battery be a good analogy for the mitochondria?
Because it is a power source. It gives energy.
Do plants or animals have specialized cells?
BOTH!
