Science Flash Cards
(24 cards)
Biological science applied to industrial or other technological purposes.
Biotechnology
Reproduction not requiring fertilization.
Asexual reproduction
The basic unit of all living things.
Cell
The process in which a cell splits into two; part of the process in which cells reproduce.
Cell division
The boundary that surrounds a cell and controls which substances can enter and leave the cell.
Cell membrane
An organelle in a cell that holds the cells DNA.
Cell nucleus
A stiff structure that surrounds and protects a cell; found in plant, fungus and some bacteria cells.
Cell wall
The process by which a less-specialized cell such as a stem cell becomes a more-specialized cell such as a blood cell.
Cell differentiation
A feature of an organism; something you can observe about an organism.
Characteristic
Found in a nucleus of a cell, a long nucleic acid molecule containing the genetic instructions for the development and functioning of all living organisms; abbreviation for deoxyribonucleic acid.
DNA
An animals female reproductive cell.
Egg
An early stage in the growth of an organism in which the organism is made of a small number of cells.
Embryo
Belonging to the biological sex the produces gametes.
Female
The reproductive cells: eggs (female) sperm (male).
Gametes
The basic unit of heredity in a living organism; a segment of DNA or RNA.
Gene
A genetically determined condition or characteristic.
Genetic trait
Internal genetic coding passed on from one generation to the next.
Genotype
Belonging to the biological sex that produces gametes.
Male
The cell division process that creates egg and sperm cells.
Meiosis
The process of cell division where one cell splits into two identical cells
Mitosis
The center of an atom contains protons neutrons a region in a cell that is surrounded by a membrane and contains genetic material.
Nucleus
A new organism that is the product of reproduction.
Offspring
A male reproductive cell that can fertilize an egg cell.
Sperm cell
A tightly wound bundle of DNA and proteins found in the nucleus of most living cells.
Chromosome
