Reproduction of offspring without the use of sex cells. |
|

|
Binary Fission |
A type of asexual reproduction in amoebas and other organisms in which a parent cell divides exactly into two identical cells. |
|
Biological Diversity |
The variety of species and ecosystems on earth. The 3 main diversity groups are; ecosystem diversity, community diversity, and genetic diversity. |
|
Biotechnology |
The use of living things to make agricultural, industrial, or medicinal products. |
|
Budding |
A type of asexual reproduction in which a new organism develops from an outgrowth, or bud, on the parent. |
|
Commensalism |
The relationship between species in which one species benefits, and the other species neither benefits nor is harmed. |
|
Continuous Traits |
Variation of traits/ characteristics such as body weight or height that are distributed on a continuum throughout a species, rather than grouped with discrete categories. |
|
Cuttings, runners, tubers, bulbs, suckers |
Cuttings- Reproduction by putting the cut end of a shoot into water or a moist earth and roots will grow. Runners- Horizontal stems grow from a parent plant that grow above ground. Buds touch the ground they root and reproduce. Tubers- Underground stem that's bearing buds where new plants grow. Bulbs- Swollen leaves stored with food. A terminal bud produces and new plants will grow. Suckers- A part of the plant that grows from the root or lower stem to grow a new plant. |
|
Cleavage |
The first divisions of a fertilized egg. |
|
Chromosome |
A structure in which DNA is arranged and along which genes are located. |
|
Community |
A group of populations of different species living in the same area. |
|
Cross-Fertilization |
The joining of a gamete from a pollen grain and a gamete from an ovule to form a zygote. |
|
Cloning |
Process of creating a clone. |
|
Consumer |
An organism that feeds off of other organisms |
|
Decomposer |
An organism, especially a soil bacterium, fungus, or invertebrate, that decomposes organic material. |
|
Discrete Traits |
A discrete trait is a trait which doesn't have a range of phenotypes. For example; tongue rolling is a discrete trait. Some people can do it, some can't. |
|
DNA |
Deoxyribonucleic acid, genetic material found mainly in the nuceli of cells of living things. |
|
Dominant Trait |
The outward form observed when two opposite- acting alleles are inherited. EX; long leg length in fruit flies; an offspring with one short-leg allele and one long-leg allele will grow long legs; the short leg allele is recessive because it has no influence if a dominant, long-leg allele is present. |
|
Extirpation |
Extinction of an organism from a specific region. |
|
Ex-situ Conservation |
The maintenance of organisms outside of their ecosystems or natural habitats; an endangered species maintained in a zoo is an example. |
|
Embryo |
An undeveloped organism in its beginning stages. |
|
Endangered |
A species at risk of extinction. |
|
Ecosystem |
A particular environment where living things interact with other living things and non-living things. |
|
Extinction |
No longer in existence on the planet. |
|
Fertilization |
The union of a female sex cell and a male sex cell. |
|
Gametes (eggs cells, sperm cells) |
A sex cell, either female or male, that can unite with another to form a fertilized cell (zygote) that can develop into a new individual |
|
Gene |
A segment of DNA located at one particular place on a chromosome, which determines a specific characteristic of an organism. |
|
Genetic Engineering |
The intentional altering of DNA of an organism or a population of organisms. |
|
Heritable characteristics |
Characteristics that are transmitted from generation to generation such as eye colour |
|
Habitat Destruction |
The process in which natural habitat is rendered unable to support the species present. In this process, the organisms that previously used the site are displaced or destroyed, reducing biodiversity. |
|
Hybrid |
An organism produced by crossing two individuals purebred for different forms of a trait |
|
Interspecies Competition |
Two or more species using the same limited resource |
|
In-vitro Fertilization |
A specialized technique by which an ovum, especially a human one, is fertilized by sperm outside the body, with the resulting embryo later implanted in the uterus for gestation. |
|
Interspecies |
Existing or occurring between species |
|
Incomplete Dominance |
The appearance in a heterzygote of a trait that is intermediate between either of the trait's homozygous phenotypes |
|
Invasive Species |
A species of plant, fungus or animal that was not originally in that area and can cause damage to the environment, human economy or human health. |
|
Intraspecies |
Arising or occurring within a species. |
|
In-situ Conservation |
Maintaining wild plants and animals in their functioning ecosystems. |
|
Mitosis |
A type of cell that will produce two twin daughter cells from one parent cell. |
|
Mutualism |
The relationship between two species in which both species will benefit. |
|
Meiosis |
The cell division that will produce 4 sex cells from one parent cell, and each cell will contain/have the genetic material of the original parent cell |
|
Niche |
The job of an individual organism or species in an ecosystem. This includes; habitat, food, reproduction, and interaction with other living and non-living things. |
|
Natural Selection |
A natural process in which the environment 'selects' which individuals will survive and reproduce depending on their traits. |
|
Non-Heritable Characteristics |
Characteristics caused by the environment, like tanned skin is caused by the UV rays from the sun. |
|
Overspecialization |
Species that has adaptions for certain environmental conditions which makes them vulnerable to extinction if the climate/ environment/ habitat changes. |
|
Population |
A group of organisms of the same species that are living in the same area. |
|
Pollination |
Process in which pollen is taken to the female reproduction organ of the plant, which starts fertilization. |
|
Purebred |
In this case, a plant or animal that was bred to consist of certain cells to create a new species. |
|
Producer |
