Biology 1 - Semester 1 Review Exam
Questions and Answers 100% Pass
Metric System - ✔✔p. 19 Measurement system whose divisions are powers of 10.
Example: meters (length), liters (volume), or grams (mass)
Testable Question - ✔✔A question that can be answered by the scientific method.
Example: "How does ___(IV)____ affect _____(DV)____"
Variable - ✔✔p. 19, A factor that can change in an experiment. Example: Independent
Variable, Dependent Variable, Controlled Variable
Prokaryotic Cell - ✔✔p. 186 a cell without a nucleus or other membrane-bound
organelles. Example: Bacteria
Nucleus - ✔✔p. 186 in eukaryotic cells, the central membrane-bound organelle that
manages cellular functions and contains DNA. Example; see picture
Organization - ✔✔p. 8 orderly structure shown by living things. Example: cells make
up tissue, which makes up organs, which make up an organism

,Scientific Method - ✔✔p. 16 a series of problem-solving procedures that might include
observations, forming a hypothesis, experimenting, gathering and analyzing data, and
drawing conclusions. Example: you see that some plants grow taller than others,
hypothesize that this is because of temperature, then conduct an experiment to form a
conclusion.
Taxonomy - ✔✔p. 485 branch of biology that identifies, names, and classifies species
based on their natural relationships. Example: Wolves = Canis lupis, domestic dogs =
Canis familiaris. They are classified as different species in the same family.
Fungi - ✔✔One of the 5 kingdoms, heterotrophic and eukaryotic. Consists of
mushrooms, yeast, mold, etc.
Kilometer - ✔✔1000 meters. A good unit for measuring long distances.
Kingdom - ✔✔large taxonomic group that consists of species of the same type. e.g.
Plantae, Animalia, Fungi, Protista, Bacteria
Membrane-bound organelle - ✔✔enclosed by a membrane and separate from cytoplasm
Meter - ✔✔Basic metric unit for measuring length
Microscope - ✔✔An instrument that makes small objects look larger
Millimeter - ✔✔One thousandth of a meter. A good unit for measuring VERY small
lengths such as the thickness of a coin, or the width of your pinky nail

, Multicellular - ✔✔An organism that consists of 2 or more cells
Photosynthesis - ✔✔Physiological process that transform sunlight energy into food for
the plant. Removes carbon dioxide from the atmosphere
Pre-Existing - ✔✔a term that means "already there"
Reproduction - ✔✔The process of producing offspring. Can be sexual or asexual.
Stimulus - ✔✔A change in an organism's surroundings that causes the organism to
react
Response - ✔✔an organism's reaction to a stimulus
Unicellular - ✔✔An organism that consists of only one cell
Growth/development - ✔✔an individual changes throughout its lifespan
Chemical Energy - ✔✔the type of energy obtained by consumers, this energy is in the
molecular bonds of the food an organism eats.
Light Energy - ✔✔the type of energy obtained by producers from the sun
Producer/Autotroph - ✔✔the name for organisms who can capture the sun's energy to
perform photosynthesis.
Consumer/Heterotroph - ✔✔the name for organisms that must obtain energy by
consuming other organisms. Could be herbivores, carnivores, or omnivores.
