What is the cell?
100
This substance is the most abundant in living things.
What is water?
100
The cells of all living things use this to carry out their functions. They get it by making or taking in food containing chemicals such as carbohydrates, lipids, and proteins.
What is energy?
100
Until the mid-1800s this mistaken idea had people believing baby mice were made by piles of rags.
What is spontaneous generation?
100
This need of living things provides energy and nutrients.
What is food?
200
This word describes organisms made of only one cell.
What is unicellular?
200
This chemical provides living things with energy.
What is carbohydrate?
200
All living things respond to surroundings. In order to do so, an organism must be able to react to this change in its environment, such as a loud noise or increase in air temperature.
What is a stimulus?
200
In the mid-1600s this Italian scientist tried to convince everyone that maggots and flies did not come from rotting meat, but the people weren't "ready".
What is Francesco Redi? (or just "Redi")
200
This need of living things allows organisms to obtain chemicals from their surroundings, break down food, grow, move substances within their bodies, and reproduce. It can dissolve more chemicals than any other substance on Earth.
What is water?
300
This word describes organisms made of many cells, each specialized to carry out certain jobs.
What is multicellular?
300
These two chemicals are used by cells as building materials.
What are proteins and lipids?
300
Examples of this include when you jump out of the way when a car beeps its horn or when your pupils dilate in dim light.
What is a response?
300
In the mid-1800s this French scientist used "swan-necked" flasks to prove bacteria in broth were not created by the broth, but that they came from reproduction of bacteria from the air.
Who is Louis Pasteur? (or just "Pasteur")
300
This need of living things might also be called a habitat. It provides room to satisfy all the other basic needs of life.
What is living space?
400
The invention of this device made the discovery of cells possible.
What is the microscope?
400
These chemicals provide the instructions needed to direct the cells activities.
What are nucleic acids?
400
We know all living things grow, but this other characteristic of living things explains why you definitely are not a big baby.
What is development?
400
In this type of experiment a scientist carries out two tests that are identical in every respect except for one factor.
What is a controlled experiment?
400
The need to maintain stable internal conditions is also known by this word.
What is homeostasis?
500
Organisms in these two domains of living things are each made of one extremely small and very simple cell.
What are Archaea and Bacteria?
500
The abbreviation for this molecule is DNA.
What is Deoxyribonucleic Acid?
500
This characteristic of living things is something offspring of two members of the same species can do.
What is reproduce?
500
This is the variable a scientist deliberately changes in an experiment. It is sometimes also called the "independent variable".
What is a manipulated variable?
500
The first term describes organisms that can make their own food, and the second term is for those that get energy from other living things.
