Pieces of information gathered during a scientific investigation
What is DATA.
German physiologist and histologist who in 1838 formulated the cell theory (1804-1881).
Who is Matthais Schleiden.
cells that contain a nucleus and organelles, and are enclosed by a plasma membrane.
What are Eukaryotic Cells.
The cells used during sexual reproduction to produce a new individual organism or zygote.
What are GAMETES.
A group separated from the rest of the experiment, where the independent variable being tested cannot influence the results.
What is a CONTROL GROUP.
Austrian monk and botanist; founder of the science of genetics.
Who is Gregor Mendel.
When an individual has two of the same allele, whether dominant or recessive.
What is HOMOZYGOUS.
A cell that contains a single set of chromosomes.
What is HAPLOID.
A step by step method used to explain the natural world
What is the SCIENTIFIC METHOD.
Dutch pioneer microscopist who was among the first to recognize cells in animals and who gave the first accurate descriptions of microbes and spermatozoa and blood corpuscles (1632-1723).
Who is Anton van Leeuwenhoek.
The set of genes in our DNA which is responsible for a particular trait.
What is GENOTYPE.
The process in eukaryotic, sexually-reproducing animals that reduces the number of chromosomes in a cell before reproduction.
What is MEIOSIS.
A statement about what observations and data mean; tells if the hypothesis was supported or not supported
What is a CONCLUSION.
German physiologist and histologist who in 1838 and 1839 identified the cell as the basic structure of plant and animal tissue (1810-1882).
Who is Theodor Schwann.
One of the possible forms of a gene.
What is an ALLELE.
Having paired sets of chromosomes in a cell or cell nucleus.
What is DIPLOID.
The variable that is changed or controlled in a scientific experiment. It represents the cause or reason for an outcome.
What is an INDEPENDENT VARIABLE.
German pathologist who recognized that all cells come from cells by binary fission and who emphasized cellular abnormalities in disease (1821-1902).
Who is Rudolf Virchow.
The physical expression, or characteristics, of that trait.
What is PHENOTYPE.
Mitosis is the step in the cell cycle that the newly duplicated DNA is separated, and two new cells are formed.
What is MITOSIS.
