Lesson 1
All living things are made of one or more cells. The cell is the smallest unit of life, and all cells come from preexisting cells.
What is cell theory?
A flexible covering that protects the inside of a cell from the environment outside a cell.
What is a cell membrane?
What is diffusion?
The process in which a series of chemical reactions converts food energy into usable ATP energy for a cell. (cell digestion)
What is cellular respiration?
SPIN! THAT! WHEEL!
This is the part of the game where Mr. Boeder spins a great big (digital) wheel that determines how many points your team will wager to answer the question that Mr. Boeder will read for you off a card. No, you may not know the question before the wager; that is the point of this mini-game. Thank you very much.
Plant cells have cell walls, and animal cells do not. This is why trees hurt when you run into them face-first.
A cell substance that is formed by joining smaller molecules together.
What is a macromolecule?
A stiff structure outside the cell membrane.
What is a cell wall?
The diffusion of water molecules only, through a membrane.
What is osmosis?
This process, often associated with the creation of ethanol, is used to create energy in the body in times of distress.
What is fermentation?
The French microbiologist who invented "safe milk."
Who is Louis Pasteur?
Nucleic acids, proteins, lipids, carbohydrates
What are macromolecules?
A cell wherein its genetic material is not surrounded by a membrane?
What is a Prokaryotic cell?
(Daily Double)
What is the difference between active transport and passive transport?
Active transport is the movement of substances through a cell membrane only by using the cell's energy. (endocytosis/exocytosis) Passive transport is the movement of substances through a cell membrane without using any of the cell's energy. (osmosis/diffusion)
The powerhouse of the cell.
What is mitochondria?
M.E.L.T.S.
What is the acronym for the types of energy commonly discussed in Science? (Specifically, physics and chemistry)
A network of threadlike proteins that are joined together, which form the framework of a cell.
What is a cytoskeleton?
A cell wherein its genetic material is almost always surrounded by a membrane.
What is a Eukaryotic cell?
Why is facilitated diffusion passive transport and not active transport?
While facilitated diffusion makes use of transport proteins, called carrier proteins, to carry large objects through a cell membrane, or channel proteins, to open tunnels through the cell membrane, the cell itself does not expend energy moving the molecules. The proteins do.
An organelle that stores food, water, and waste material for plant and animal cells.
What is a vacuole?
S.T.E.A.M.
What is the acronym for Science, Technology, Engineering, Arts, and Math?
Directs cell activity.
What is the nucleus?
A fluid that contains salts and other molecules in a cell. It also contains the cytoskeleton.
What is cytoplasm?
Specialized structures that perform specific functions for a cell, usually surrounded by membranes.
What is an organelle?
The part of a plant cell that performs photosynthesis?
What is a chloroplast?
This person has called you on the telephone. As it turns out, you are, in fact, NOT the center of the universe.
Who is Nicolaus Copernicus?
