Parts Of A Flower
Male reproductive part of the plant.
The Anther and filament
what is pollination
the transfer of pollen from one Anther to the stigma
Asexual Reproduction Methods
Cuttings and Division/Separation, Grafting, Layering, and Tissue Culture.
complete flowers need
sepals, petals, stamen, and pistil
Why is sexual reproduction easier?
Seeds are easily stored from year to year and over a long period of time
An inexpensive way to grow a large number of plants
Easy to do and usually does not require special skills
Female reproductive part of the plant.
The stigma,style, and ovary
name one way pollination can occur naturally
by wind, water, or animals
Disadvantages of Asexual Reproduction
The main disadvantage is the potential for impact on biodiversity of a species
incomplete flowers don't have one
sepals, petals, stamen, and pistil
What are sexual reproduction disadvantages?
Offspring are genetically different from parents so desirable traits can be lost or depleted
Germination rates can be low
Length of time to a mature plant can be long
what part of the flower attracts pollinators
petal
what is it called when a plant pollinates itself
self-pollination
What is Grafting
method commonly used on trees by orchards and nurseries
Monoecious
plants that have male and female flowers on the same plant
What is tissue culture
Entire new plants are grown from small pieces of plant tissue placed in artificial media under sterile conditions.
What is the sticky part of the pistil that catches pollen
stigma
what is cross pollination
pollen from one flower fertilizes another flower
what is union
where the two grafts meet
Dioecious
plants that have male and female flowers on separate plants
what part connects the stigma to the ovary
style
why is pollination important
it allow plants to reproduce and form seeds
Advantages of Asexual Reproduction
keep best characteristics pure or shorten the time to produce a mature plant versus starting from a seed.
The colorful part of the flower
The petals
