Discovering Cells
This is the basic unit of structure and function in all living things.
What is a cell?
This type of cell contains a cell wall and large central vacuole.
What is a plant cell?
These two systems work together most closely to get every cell in the body the nutrition it needs.
What are the digestive and circulatory systems?
These is the order of the 4 lower levels of organization that lead to a complete multi-cellular organism.
What is cell, tissue, organ, and organ system?
This is the one intentional change a scientist makes to an experiment to determine what the effects of the change are.
What is the independent variable?
This process occurs in any living organism when food is broken down into nutrient molecules.
What is digestion?
This type of cell does not contain a nucleus, but has ribosomes, a cytoplasm, and a cell membrane at minimum.
What is a prokaryotic cell?
(Also accept bacteria)
These two systems must work together for the human body to be able to move correctly.
What are the skeletal and muscular systems?
When looking at how things are organized in multicellular organisms, this is a group of cells that all perform a specific function.
What is tissue?
These are all the variables in an experiment that must be kept the same every trial in order to have valid results.
What are the control variables?
This term refers to an organism's (or cell's) ability to maintain stable internal conditions despite changes in the environment.
What is homeostasis?
These are the four main organelles that animal and plant cells have in common.
What are the nucleus, mitochondria, cell membrane, and vacuoles?
(accept ribosomes and cytoplasm)
These two systems work together to deliver oxygen and remove carbon dioxide from every cell in the body.
What are the circulatory and respiratory systems?
In this level of organization, two or more organs work together to carry out a specific function necessary for life for complex multicellular organisms. Each of these organs will have a different "job."
What is an organ system?
What are the experimental and control groups?
All living thigs require this abundant non-living resource in order to complete basic cell functions.
What is water?
This is the outer most part of a plant cell.
What is the Cell Wall?
This system has the primary function of sending communication signals throughout the body. It is at work whenever involuntary movements are required to avoid damage or maintain homeostasis in changing conditions.
What is the nervous system?
This is the type of tissue you would expect to find in the brain. Its function is to help the body communicate internally.
What is nervous tissue?
This is what the scientist looks for to determine whether or not the changed variable had any impact on the results.
What is the dependent variable?
What is the theory of Spontaneous Generation?
This type of human pathogen results in mild illnesses and is often accompanied by a rash or bumps when observed on the skin. It is a living thing, and therefore a specific type of cell. What type of cell is it?
What is a fungal cell?
(also accept fungus)
This body system contains these organs: kidneys, bladder, urethra. It even sometimes involves the skin and lungs.
What is the urinary system?
Also accept: excretory system
This type of tissue lines the outside of the body and also every organ within the body. Its function is to protect the rest of the body from harm coming from the outer environment.
What is epithelial tissue?
A scientist wanted to demonstrate that local honey alleviates allergies. He asked a group of people to start having a teaspoon of honey every day during allergy season and then documented whether or not each person had a runny nose, sneezing, or headaches. Only one had some symptoms, but the scientific community rejected his conclusion that local honey can treat allergies. This is what he did wrong.
