Biology 1010 Midterm Review Questions with Answers
(100% Correct Answers)
Reductionism Answer: An approach to understanding the nature of
complex things by reducing them to the interactions of their parts, or to
simpler or more fundamental things
Robert Hooke Answer: In 1665, he first described and named cells from
an oak tree
Anton van Leeuwenhoek Answer: Discovered a microbial world in
droplets of pound water
Schleiden and Schwaan Answer: Called cells 'units of life' - cell theory
Common features of Cells Answer: All cells are enclosed by a membrane
that regulates passing of materials between the cell and it's surroundings.
Every cell contains DNA.
Two major kinds of cells, Prokaryote and Eukaryote.
Eukaryotic vs. Prokaryotic Answer: Eukaryotes: Have a nucleus,
membrane bound organelles. Much more complex DNA, which is held in

the nucleus. Prokaryote DNA floats freely, and are 10% the size of
Eukaryotes. They have a cell wall of peptidoglycan.
Genes Answer: The basic physical and functional unit of heredity which
are made up of DNA, act as instructions to make molecules called
proteins. In humans, they vary in size from a few hundred DNA bases to
more than 2 million bases.
Evidence for unity of life Answer: A universal genetic code, similar
metabolic pathways, and similarities of cell structure.
Three Domains/Five Kingdoms Answer: Domain Bacteria and Archaea
both include Kingdom Prokaryota. Domain Eukarya includes the
kingdoms of Protista (unicellular eukaryotes), Fungi, Plantae, and
Animalia.
Taxonomy Answer: Domain - Kingdom - Phylum - Class - Order - Family
- Genus - Species. DKPCOFGS.
Evolution Answer: The process by which different kinds of living
organisms are thought to have developed and diversified from earlier
forms during the history of the earth.

Darwin's Observations and Inferences Answer: Observation 1: Individual
Variation. Individuals vary in many heritable traits. Observation 2:
Struggle for existence. The produced offspring is far bigger than the
environment can support.
Inference: Differential reproductive success. Those individuals with traits
best suited for local environment leave a larger number of surviving
fertile offspring.
3 Properties of living things Answer: Metabolism, Growth, Reproduction.
Life's hierarchy Answer: Molecules, Organelles, Cells, Tissues, Organs,
Organisms, Populations.
The Cell Theory Answer: 1. Cells are the fundamental units of life, a cell is
the simplest unit capable of independent existence.
Plant cell structure Answer: Eukaryotic cells that differ in several key
aspects from the cells of other eukaryotic organisms.
Plastids Answer: A major double-membrane organelle found, among
others, in the cells of plants and algae. They are the site of manufacture
and storage of important chemical compounds used by the cell.
