Character-istics
Living things are made up of these basic units.
What are cells?
The “control center” of the cell.
What is the nucleus?
Green pigment in plants that captures sunlight.
What is chlorophyll?
These are single-celled organisms that can be helpful (like in yogurt) or harmful (like strep throat).
What are bacteria?
Information you collect during an experiment is called ___.
What is data?
All living things must take in and use this for energy.
What is food (or nutrients)?
The smallest unit of life.
What is a cell?
The process plants use to make their own food.
What is photosynthesis?
This group includes molds and mushrooms, and they decompose dead material.
What are fungi?
The part of the experiment you measure or observe as a result.
What is the dependent variable?
The process by which living things make more of their own kind.
What is reproduction?
These are the two main types of cells.
What are plant cells and animal cells?
Tiny openings on leaves that let gases in and out.
What are stomata?
Yeast is an example of this type of organism that helps bread rise.
What is fungi?
The group in an experiment that does not get the independent variable, used for comparison.
What is the control group?
Living things respond to changes in their environment, called ___.
What are stimuli?
These are green jellybean like parts in a plant cell.
What are chloroplasts?
Plants are producers because they make their own food. The scientific word for this is ___.
What is autotroph?
The invention that allowed scientists to first see bacteria and protists.
What is the microscope?
Scientists repeat experiments many times to make sure results are ___.
What is reliable (or accurate/valid)?
This is the ability of living things to keep internal conditions stable.
What is homeostasis?
Plant cells have this outer layer, but animal cells do not.
What is the cell wall?
These tube-like structures move water from the roots up through the plant.
What are xylem?
Unlike bacteria, these are not truly alive and need a host cell to reproduce.
What are viruses?
The part of the experiment that you change on purpose.
What is the independent variable?
