Strategies for Survival Flashcards
sexual reproduction
A reproductive process that involves two parents that combine their genetic material to produce a new organism, which differs from both parents
asexual reproduction
A reproductive process that involves only one parent and produces offspring that are identical to the parent.
Fertilization
Process in sexual reproduction in which male and female reproductive cells join to form a new cell
internal fertilization
fertilization of an egg by sperm that occurs inside the body of a female
external fertilization
The process by which the female lays eggs and the male fertilizes them once they are outside of the female

Stamen
Male part of the flower
Anther

filament
Supports the anther
pollen
A fine dust that contains the sperm of seed-producing plants
ovule
A structure that contains an egg cell
Pollination
The transfer of pollen from male reproductive structures to female reproductive structures in plants
pollinator
An animal that carries pollen from one plant to another of the same species, enabling plants to reproduce.
competition
the struggle between organisms to survive in a habitat with limited resources
Tropism
A growth response of a plant toward or away from a stimulus
Symbiosis
A relationship in which two different organisms live in close association with each other
Parasitism
A relationship between two organisms of different species where one benefits and the other is harmed
Mutualism
A relationship between two species in which both species benefit
Commensalism
A relationship between two organisms in which one organism benefits and the other is unaffected
Pesticides/Herbicides
Substances used for destroying things that are harmful to growing plants
Pesticides
chemicals used to repel insects from crops
Herbicides
chemicals used to repel weeds in soild
fertilizer
a chemical or natural substance added to soil or land to increase its fertility
Invasive alien species
