Biology Unit 1 Vocabulary
Review Flashcards
Know our Lab Safety Rules
Review all lab safety rules in the lab
What is BIOLOGY?
Study of Life (Living things)
Bio=Life ology=Study of
What is goal of science?
To get answers to questions about our natural
world.
What is an OBSERVATION?
What you see happen in an experiment.
Either qualitative or quantitative
Use senses (hearing, seeing, feeling, etc. to
make observations
What is DATA?
Information collected from conducting an
experiment to be analyzed.
What is QUALITATIVE data?
What is QUANTITATIVE data?
What are the steps to the
Scientific Method?
Understand importance of each step
Observations (data) using your 5 senses
Feel, smell, hear, taste, see, such as a color or
taste which aren’t numerically measured
values.
Numbers for data (length 10 cm, volume 10 ml,
mass 10 g)
Observe something
Problem or Question
Hypothesis – Must be able to be tested
Experiment
Data Analysis
Conclusion
Report your findings
VARIABLES
What is an Independent variable (IV)?
What is the Dependent variable (DV)?
Things that are changed in an experiment; two
types: IV and DV
The thing that “I” change in the experiment
(such as different amounts of sunlight a plant
gets)
The data obtained from your experiment
(such as the height the plant grew)
What is a CONTROL group?
Used as a COMPARISON tool for your data.
It does NOT get the IV.
(such as the plant that gets normal amt of light)
What is a Zero Treatment Control?
Control group gets NO treatment Ex:
No jumping jacks and measure pulse vs.
100 jumping jacks and measure pulse
What is an Experimenter Selected Control?
The experimenter chooses the control.
Ex: Regular dog food and dog growth vs.
New improved dog food and dog growth
What is the EXPERIMENTAL group?
The samples that get the I.V. in the experiment.
Ex: Plants that get 2, 4, 6 hours of sunlight to
see how they grow as compared to the control
plant that gets 8 hours of sunlight.
What are CONSTANTS?
The things that are given to the experimental
group and control.
(such as same amount of water, type of soil,
type of plant, size of container)
What is a THEORY?
A well tested hypothesis that is supported by
repeated testing.
Know the Metric system
and
How to perform Conversions.
Kilo
Hecto
Deka
Base Unit - Meter, Liter, Gram
Deci
Centi
Milli
What phrase helps you remember how to
convert units?
King Henry Died By Drinking Chocolate Milk
Name the Levels of Biology from largest to
smallest and define each
What are the 8 Characteristics of Life?
Think about what we as a human species need
to survive and not become extinct.
Biosphere = All areas of earth with life
Ecosystem = Living and non-living in an area
Community = Diff species in an area
Population = Same species (organisms) in an
area
Organism = Group of organ systems
Organ system = Group of organs
Organ = Group of tissues
Tissue = Group of cells
Cell= SMALLEST LIVING THING
Molecule = Units that make up cells NOT
Metabolize gain and use energy (food)
Made of at least 1 or more cells
DNA (Universal Genetic Code) Genetics
React to environment (Put on coat when cold)
Adapt/Evolve to environment (More fur in cold
climates)
Homeostasis – Maintain stable internal environ
Grow and Develop (Baby to adult to old man)
Reproduce (to keep our species alive)
SPECIES
An organism that can reproduce and produce
fertile offspring. Mules are not a species!
METABOLISM
The ability to get and use energy
HOMEOSTASIS
Keeping a stable internal environment
Unit of measure in Metric System for
Mass
Length
Volume
Temperature
Gram (gm)
Meter (m)
Liter (L)
Celsius (°C)
Compound Light Microscope
Different lenses for magnification
Can see live or dead organisms
Bacteria
Uses light to show image
Stains
Help to see the specimen better under the
microscope
Transmission Electron Microscope
Shows inside of specimen
Specimen must be dead
Uses electrons passed THROUGH a specimen to
create image
TEM
Scanning Electron Microscope
SEM
Shows outside of specimen
3D image
Specimen must be dead
Uses electrons on SURFACE of specimen to
create shape of object
Cell Fractionation
Getting the parts of the cell by
using centrifuge to separate parts
Cell Culture
Grow a bunch of cells from one or a few cells
What is a Botanist?
Studies Plants
What is a Zoologist?
Studies Animals
