Ecosystems and Interdependence
These are a variety of living things.
Characteristics that are acquired.
What are non-heritable characteristics?
The general term for reproduction that is possible with one parent.
What is asexual reproduction?
This is the process that occurs when a male and female gamete unite.
What is fertilization?
This is an environment that living things exist in.
What is an ecosystem?
This type of reproduction usually involves 2 organisms.
What is sexual reproduction?
These are the three types of symbiosis.
What is mutualism, parasitism, and commensalism? (in any order)
When changes to the environment occur and the environment chooses which organisms are best suited to survive.
What is natural selection?
Single celled organisms splitting into two.
What is binary fission?
It takes 5-9 days for a zygote to be at this stage.
What is an embryo?
Non-living things are called this.
What is abiotic?
This is the male gamete in a flowering plant.
What is pollen?
This is the type of competition where animals between species compete for food and territory.
What is interspecies competition?
Eye color, hair type, skin color, and height are all examples of these kinds of characteristics.
What are heritable characteristics?
Often done by fungi, spreading of seeds that were not the result of mating.
What is spore production?
This is the male reproductive organ within a plant that has a flower.
What is the stamen?
This refers to all living things in an ecosystem.
What is community?
This is the female reproductive organ within a plant that has a flower.
What is the pistil?
This is how an organism gets its energy, where it lives (habitat), and its effect on abiotic and biotic factors in its ecosystem.
What is niche?
Earlobe attachment, Hitchhiker's thumb, and skin color are all examples of this type of variation.
What is discrete variation?
When plants reproduce by using runners, or plants are bulbs and tubers, they follow this type of asexual reproduction.
What is vegetative reproduction?
This type of fertilization in a plant occurs because the pollen is carried into a different plant by wind, water, or animals.
What is cross pollination?
Organisms best adjusted for their environment are the most successful in reproducing and surviving
What is the survival of the fittest?
This is the process known when a zygote undergoes cellular division as it develops.
What is cleavage?
An imaginary line around the center of the world where biodiversity is high.
What is the equator?
These are two of the three reasons that causes genetic variation.
What is genetic mutation, gene flow, and sexual reproduction? (just name two)
There is no energy wasted in finding a mate, which allows asexual reproduction to occur rapidly.
What is an advantage of asexual reproduction?
This process of cellular division creates gametes.
What is meiosis?
When resources, like food or habitats, are split up in order to avoid competition within species.
What is resource partitioning?
This type of cellular division creates new somatic cells (cells of the same variety)
What is mitosis?
