Microscopes
What are the names of the two kinds of microscopes that we covered?
Compound Microscope/Electron Microscope
Any substance that cannot be broken down into smaller substances.
What is an element?
This organelle is the powerhouse of the cell! More importantly, it converts energy in food to energy the cell can use.
What is a mitochondria?
Basic units of structure and function in living things.
What are cells?
What are the two kinds of cells that we learned about?
Plant and Animal cell.
How do the two kinds of microscopes that we covered work?
Compound uses light focused through lenses to produce magnification. Electron uses beams of electrons.
Two or more elements combined chemically.
What is a compound?
This substance fills the region between the cell membrane and the nucleus.
What is cytoplasm?
The relationship between cells and living things?
What is cell theory?
What two parts distinguish a plant cell from an animal cell?
The Cell Wall and the Chloroplasts.
The condition of things that appear larger than they are.
The four organic compounds that living things need.
What are carbohydrates, lipids, proteins, and nucleic acids?
This organelle packages and distributes substances?
Almost like a warehouse.
What is the golgi apparatus?
What are the three premises of cell theory?
1. All living things are composed of cells
2. Cells are the basic units of structure and function
3. All cells are produced from other cells
Daily Double!
1. Made of many cells.
2. A group of cells working together.
1. Multicellular
2. Tissue
The degree to which two separate structures that are close together can be distinguished.
What is Resolution?
These three elements are found among all living things.
What are Carbon, Hydrogen, and Oxygen?
This organelle produces proteins.
What is a ribosome?
Name at least three functions of organisms and cells.
Obtain food, obtain oxygen, obtain water, get rid of wastes.

How many cells are in a human body?
(*HINT - between 1 - 50 trillion, take a guess, within 5 trillion is a win)
About 37.2 trillion cells in a human body.
Two significant scientists and researchers that helped develop microscopes and cell theory.
Hooke and Leeuwenhoek
Daily Double!
1. This Inorganic compound is necessary for life.
2. This is the shape of a DNA molecule.
1. What is water?
2. What is a double helix?
How many different organelles are in a plant cell? (include cytoplasm and lysosomes)

Do stuffed animals have the same kind of cells as humans? Why or why not?
No, because stuffed animals are not alive and do not reproduce. They are not made of cells like humans.
