cones
Pollinated by
animals
Example:
Number the order in which the steps in the life cycle of a moss occur. Start with the step labeled “1.”
__1__ A zygote at the tip of a gametophyte develops into a new sporophyte, which remains attached to
the gametophyte
_____ The moss spores settle to the ground, and they germinate and grow into “leafy” green
gametophytes.
_____ The gametophytes produce gametes.
_____ When the spore capsule opens, the spores are carried away by wind or water.
_____ A mature sporophyte produces spores within the spore capsule by meiosis.
_____ Motile sperm swim to, and fertilize, eggs.
Number the order in which the steps in the life cycle of a fern occur. Start with the step labeled “1.”
__1__ The zygote grows into a new sporophyte.
_____ A mature sporophyte produces spores.
_____ Sperm swim through a film of water and fertilize eggs.
_____ The mature gametophytes produce gametes.
_____ The spores fall to the ground and grow into haploid gametophytes.
Number the order in which the steps in the life cycle of a pine tree. Start with the step labeled “1.”
__1__ A mature pine produces male and female cones
_____ The zygote and ovule develop into a seed, which grows into a new sporophyte
_____ Sperm enter the ovule through a pollen tube, and fertilization occurs
_____ Male and female spores form on the scales of the cone
_____ Pollination occurs when a pollen grain lands near an ovule
_____ Spores develop into male and female gametophytes
Indicate the order in which the following evolutionary events took place.
_____ sperm swim through film of water
_____ pollination
_____ gametophytes produced within cones
_____ vascular tissue
_____ gametophytes produced within flowers
_____ independent gametophytes
