Scientific Design
A thermometer that is not calibrated correctly will consistently give the wrong temperature readings. This is an example of this type of error.
A systematic error
What do we call a living thing that is made up of just one cell?
Unicellular
Name the two parts a plant cell has that an animal cell doesn't.
Cell wall & Chloroplasts
A muscle is an example of this level of organisation.
Organ
Name the five kingdoms of living things
Animals, plants, fungi, protoctists and bacteria/ monera
In a scientific paper, this section provides enough detail for another researcher to repeat the experiment.
The methods (or methodology) section
A doctor notices that a patient’s white blood cell count is extremely low. This means the patient may struggle with this essential function.
fighting infections
What part of the cell is responsible for photosynthesis?
The chloroplasts
This is several organs working together to perfom a common function.
A system
This body system is responsible for transporting oxygen, nutrients, and hormones throughout the body.
The circulatory system
A valid experiment should have only one of these changed at a time.
An independent variable
What is the liquid that makes up most of the cell?
Cytoplasm
Which four features can you find in both animal and plant cells?
Nucleus, organelles, cell membrane & cytoplasm
This is the correct order of organisation in multicellular organisms, from smallest to largest.
cell → tissue → organ → organ system → organism
Which Kingdom or kingdoms make their own food?
Plants and algae
This scientist first observed cells under a microscope and coined the term "cell."
Robert Hooke
The long, thread-like shape of muscle cells allows them to do this.
Contract and relax to produce movement.
This structure controls what enters and leaves the cell.
Cell membrane
A leaf is an example of this level of organisation.
Organ
Can Algae be multicellular, unicellular or both?
Both
A good hypothesis should be both of these two things.
Testable and falsifiable
What are the three tenants of Cell Theory
1. Cells are the basic unit of life.
2. All living things are made of cells.
3. Cells come from other cells.
Small structures, found in both prokaryotic and eukaryotic cells, are responsible for protein synthesis.
Ribosomes
A group of similar cells with the same function make what?
Tissue
The small intestine is lined with these tiny finger-like projections that increase surface area for absorption.
Villi
