D3.1 Flashcards
Plant reproduction (17 cards)
Process Pollination
Pollen from anther to Stigma
Where does Fertilization occur
In Ovule.
How does the Embryo Development
Zygotes divide by mitosis and develops into an embryo
Upper Petals
Advertise Landing site for insects
Stigma
Collects Pollen from an insects back
Anther
Produces Pollen
Filament
Holds the anther where it will rub pollen onto insects back
Lower Petals
Resist access to nectar
Style
For pollen tube growth
Ovaries
Hold Ovuals
Nectary
Deep inside Tubular flower so insects brush past anthers and stigma
Sepals
Protect flower when in Bud
Self-Incompatibility
Receiving pollen from the plants own anthers.
Caused by a single plant acting as both male and female parent
Seed Dispersal (What is transferred, From where to where, what are the agents)
Seeds, from female parent to the site of germination, wind, animals or explosion.
Polination (What is transferred, From where to where, what are the agents)
Pollen, Anther to stigma, Wind or animals
Germination
the process where a seed or spore, after a period of dormancy, begins to grow and develop into a new plant, sporeling, or other reproductive body.
