Plant Reproduction Flashcards
in plants, the hollow, lower end of the carpel containing the ovules (the female egg cells); in animals, the female organ that produces ova and reproductive hormones
ovary
receptacle within an ovary that contains egg cells
ovules
the supporting part of a flower that holds the stigma
style
long tube growing from a pollen grain through the style to the ovule
pollen tube
the male gametes of a flower
pollen grains
the male part of a flower that makes pollen
anthers
flowers that receives pollen carried by the wind from another flower
wind-pollinated flowers
flowers that receive pollen carried on the body parts of insects from other flowers
insect-pollinated flowers
transfer of pollen from stamens of one flower to the stigma of a flower of another plant of the same species
cross-pollination
transfer of pollen from the flower’s own stamen to its stigma
self-pollination
transfer of pollen from the stamen (the male part) of a flower to the stigma (the female part) of a flower
pollination
the female part of a flower, at the top of the carpel, that catches the pollen during pollination
stigma
the male sex cells of a plant
pollen
parts of a flower, at the base of the petals, that secrete nectar
nectaries
the coloured parts of a flower that attract insects
petals
the reproductive part of angiosperms containing petals, stamens and carpels. They are often colourful to attract pollinating insects
flowers
food supply for the embryo plant in a seed
endosperm
product of a fertilised ovule
seed
the protective layer around a seed
seed coat
ripened ovary of a flower, enclosing seeds
fruit
scatter the seeds from plants
disperse
small bud at the tip of the embryo plant in a seed
plumule
the beginnings of a root making up part of a plant embryo inside a seed
radicle
special leaves of the embryo plant inside a seed that provide food for the developing seedling
cotyledons
