Cell Asexual reproduction DNA Hypothesis Homeostasis Theory Controlled experiment Scientific method Classification Taxonomy Variable Dichotomous key Bacteria Binary Fission Diffusion Osmosis Prokaryotic Cells UNIT 1 Vocabulary
Cells Smallest unit of life that contains all the materials necessary for life.
DNA The genetic material found in all living organisms
The ability for all living things to maintain a stable internal environment is called • Homeostasis
An experiment that tests only one variable at a time • Controlled experiment
The arrangement of organisms into orderly groups based on their similarities • Classification
The factor in a controlled experiment that can change • Variable
The smallest and simplest organisms on the planet • bacteria
The tendency of molecules to move from an area of high concentration to an area of low concentration • Diffusion
A single parent produces offspring that are identical to the parent. • Asexual reproduction
A hypothesis that has been supported by lots of evidence and experiments • Theory
The diffusion of water molecules from an area of high concentration to low concentration Osmosis
A series of steps a scientist uses to answer or solve a problem • Scientific method
Tool used to identify unknown organisms Dichotomous Key
A cell with no nucleus Example: Bacteria • Prokaryotic cell
A possible explanation or answer to a scientific question • hypothesis
Type of asexual reproduction used by bacteria, one cell splits into two. • Binary Fission
The science of identifying, classifying, and naming living organisms • Taxonomy
Found in all cells of living organisms, and contains the blueprint of life. • DNA
The movement of molecules from an area of high concentration to an area of low concentration. • Diffusion
Now it will get a bit harder…I will give you only two or three words and you will need to give me the vocabulary word they define.
Cell Asexual reproduction DNA Hypothesis Homeostasis Theory Controlled experiment Scientific method Classification Taxonomy Variable Dichotomous key Bacteria Binary Fission Diffusion Osmosis Prokaryotic Cells Vocabulary
Steps scientist take Scientific Method
Smallest unit of life Cells
Possible explanation Hypothesis
Supported by Evidence Theory
Genetic Material DNA
No nucleus Prokaryotic Cell
Identify, classify, naming Taxonomy
Stable, internal, environment Homeostasis
Cell Division, asexual Binary Fission
Grouping by similarities Classification
Diffusion of Water Osmosis
Molecules, High to low Diffusion
Tool to identify Dichotomous key
One parent, identical Asexual reproduction
Factor that changes Variable
Now a bit harder…. I will show you a picture.. What word does it describe?
Which of these characteristics describe bacteria? • Unicellular • No Nucleus • Has a cell Wall d) Reproduces asexually e) All of the above
