Reproduction Basics
What is reproduction?
The process organisms use to make new individuals of the same species.
What is asexual reproduction?
Reproduction that involves only one parent.
What is an egg cell?
The female reproduction cell
What are humans?
An organism that reproduces sexually and has two parents.
What is inheritance?
The passing of traits from parents to offspring through DNA.
What is a gamete?
A reproductive cell such as a sperm cell or egg cell.
What is sexual reproduction?
Reproduction that involves two parents and gametes.
what is a sperm cell?
the male reproduction cell
What are bacteria?
A microscopic organism that reproduces asexually by dividing in two.
What is competition?
A situation where organisms must compete for limited food, space, or resources.
What is fertilisation?
The joining of a sperm cell and egg cell.
What does genetically identical mean?
Offspring produced through asexual reproduction are usually this genetically.
What is a fertilised egg?
sperm + egg cell → this cell forms.
What are strawberry plants?
A plant that can reproduce asexually by growing runners.
What is variation?
Differences in traits among individuals within the same species.
What is a zygote?
The first cell formed after fertilisation.
What is genetic variation?
A key advantage of sexual reproduction that helps species survive changes.
What is a zygote?
The stage of development that occurs immediately after fertilisation.
What is a hydra?
A simple aquatic organism capable of budding to reproduce asexually.
What is natural selection?
The process by which organisms with traits better suited to an environment survive and reproduce more successfully.
What is sexual reproduction?
The biological process that produces a zygote containing genetic material from two parents.
What is binary fission?
A form of asexual reproduction in which a single parent cell divides into two genetically identical daughter cells, commonly seen in bacteria.
What is fertilisation?
The process where gametes combine to restore the full number of chromosomes in the new organism.
What are runners (stolons)?
A reproductive adaptation in plants where horizontal stems grow along the ground producing new plants genetically identical to the parent.
What is environmental change?
A sudden change in environmental conditions that can threaten the survival of organisms in an ecosystem.
