Biology, Cell Division and Reproduction, Q5
calyx
consists of the sepals of a flower
male flower
contains only stamens
ovary
developed into a fruit
ovule
develops into a seed
sporophyte
diploid generation
heteromorphic alternation of generations
gametophyte and sporophyte appear to be different
isomorphic alternation of generations
gametophyte and sporophyte appear to be the same
gametophyte
haploid generation
pines and other gymnosperms
have 2 kinds of cones
pine cone seeds are produced in the
ovule of the female cone
not all flowers are able to
pollinate themselves
spores produced by the small male cone of a pine tree are
produced by meiosis
corolla
the collective term for the petals of a flower
stamen is made up of
the filament and the anther
prothallium
the gametophyte generation of a fern
sporic
the kind of life cycle seen in flowering plants
pistil is made up of
the ovary, the style, and the stigma
seeds in a pine tree are borne in
the ovulate cone
12 months
the time between the act of pollination and actual fertilization in the pine (WOW)
pollination refers to the transfer of pollen from the anther part of the plant
to the stigma part of a plant
not all flowers have
a complete set of male and female parts for fertilization
sorus
a group of fern sporangia
pollen is made in the
anther
plants produce spores in structures called
sporangia
