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
