Defining Life
100

An educated guess, a prediction, or an idea you can test. 

Hypothesis

100

This cellular organelle contains the cells DNA and controls all cell functions.

The nucleus

100

This organelle is the cell's protein making factory.

The ribosome

100

This is a word for an organism that is made of many cells. 

Multicellular

200

This is another word for informated that is gathered, organized, and analyzed during a science experiment. 

Data

200

This is the flexible barrier in plant and animal cells that determines which substances can enter or exit the cell. 

Cell membrane

200

Located near the nucleus, this organelle is made up of a series of tubes and vessels that allow materials to be transported throughout the cell. 

The endoplasmic reticulum (ER)

200

This is a word for an organism that is made of just one cell. 

Unicellular

300

These are things in a science experiment that stay the same. 

Constants

300

This is the tough outer layer in plant cells that gives the cell its shape and stability. 

Cell wall

300

This is a storage container for food, water, and waste inside the cell. 

Vacuole

300

These are living things that must consume their food in order to get the energy they need to live. 

Heterotrophs

400

This is the ONE thing in a controlled experiment that the scientist changes.

Independent Variable

400

This organelle takes food molecules and turns them into energy that the cell can use. 

Mitochondria

400

This is the cell's cleanup crew. It's job is to break down and recycle old cell parts to make new ones. 

Lysosome
400

These are living things that are capable of making their own food. 

Autotrophs

500

These are changes that occur as a result of changes made to the independent variable.

Dependent Variable

500

This organelle absorbs sunlight and turns it into sugars that the plant can use. 

Chloroplast

500

This organelle packages substances like proteins and ships them out of the cell. 

Golgi Body

500

This is a term for a living thing's ability to reproduce all on its own without help from another organism.
