Reproduction Types
These are two basic types of Reproduction
Sexual and asexual (or clonal)
The term for the investment of energy resources a plant allocates to reproduction
Reproductive effort
Name for species that
reproduce only once in
their lifetime.
Monocarpic
Benefit of sexual reproduction that provides population variability.
Genetic Recombination
Example of plants that performs sexual and clonal reproduction simultaneously
Piñuela
Reproduction type that mantains eficiente genetic traite without risa of loss through recombination.
Clonar or asexual
This reproduction type has a high energy cost due to making flowers,pollen, and fruit
Sexual reproduction
Name for species that have
several reproductive events
throughout their lives.
Polycarpic
Mobile structure that allows descendants to conquer new environments.
Seeds
Tree species where a flower production causes a decreases in leaf production
Birch
Type of propagation favored when a population has very few individuals.
Clonar or asexual.
This reproductive strategy has a medium to low energetic cost
Clonal or asexual reproductions
Life cycle of plants that
usually invest more
resources in sexual
reproduction.
Annual or biennal species
What happens to seed size when a plant produces a very high quantity of seeds.
The seed siempre decreases
The highest cost of reproduction, occuring in plant like agaves
Death of the plant
It incorporates individuals to the population in short time.
Costs associated with making these volatile substances to attract pollinators
Volatile chemical compunds
Ecosystem where up to
80% of species show clonal
propagation as a response
to stress.
Deserts
Two benefits for seedlings that come from larger seeds.
Better establishment and advantageous growth
Herbaceus species where larger invididuals spend more resources to reproduce
Common plaintain
Clonal structures used by some grasses to reproduce while remaining connected.
Stolons.
Vital physiological function that often competes with and decreses due to reproduction
Growth
Type of habitat where the
cost of sexual reproduction
is higher for the plant.
Habitats with low resource availaility (water,light,nutrients) or biotic stress
Orchid species that produces thousands of microscopic seeds,
Star Orchird (Epidendrum ciliare)
Legume capable of producing 2,000 ovules but only 50 seeds
