Cell Theory and NOS
What are all living things made up of?
What is the powerhouse of the cell?
The Mitochondria.
What process can plant cells do that animal cells can not?
Photosynthesis
Define homeostasis.
Maintaining balance in a system (Cell / Body).
Smallest level of organization of life.
Cell
Why do we not say atoms are the basic building blocks of life?
We don’t say atoms are the basic building blocks of life because atoms are found in all things, not just living things.
Does EVERY cell have a nucleus?
No; Some cells have other structures to keep DNA in.
Why do plant cells have a larger vacuole?
Give one example of homeostasis in a cell.
Name a type of tissue.
100 bonus points for drawing it.
Muscular, Epithilial / Skin, Nervous
Name one of the four parts of Cell Theory.
Bonus 100 points for each additional part added.
All living things are made of cells.
Cells are the basic unit of structure and function in living things.
All cells come from pre-existing cells.
Cells contain DNA that is passed from one generation to the next.
Name an organelle present in plant cells but not animal cells.
Chloroplast, Cell Wall, Large Vacuole
It lets in and out stuff that the cell has too much/too little of.
Give one example of homeostasis in the human body.
Temperature regulation / Blood Sugar Levels / Hydration.
Tissues group together to form...
Organs.
Explain the difference between a scientific theory and a law.
A law describes what happens under certain conditions, while a theory explains why and how it happens.
Why do plant cells have both a chloroplast and a mitochondria?
Plant cells have chloroplasts to make food from sunlight and mitochondria to turn that food into energy the cell can use.
What two gasses are exchanged between plants and animals?
Carbon Dioxide and Oxygen
How are cellular and body homeostasis related?
Cells perform functions that keep tissues/organs/organs systems stable; together they maintain the organism’s overall balance.
List all of the levels of organization we go over in class in order.
Cell > Tissue > Organ > Organ System > Organism
Name at least one limitation of scientific models.
Scientific models have limits because they are just simplified versions and can’t show everything exactly how it is in real life.
List all 5 structures found in both animal and plant cells.
Mitochondria
Nucleus
Cell/Plasma Membrane
Vacuole
Cytoplasm
Give one example of a cellular process that helps maintain homeostasis.
Removing waste OR extracting energy from food OR reproducing
Explain a scenario where the body is out of balance and what it can do to bring itself back to balance.
Varied answer responses.
What is the MAIN benefit of having multiple cells organized into different levels of organization.
The main benefit is that it allows cells to specialize and work together to do more complex jobs than a single cell could do alone.
