How has the fertilization process of seed plants adapted to dry
terrestrial conditions?
Select one:
a. stomata close to prevent water loss
b. the evolution of a pollen tube eliminated the need for water in
the transfer of sperm to the egg
c. the pine needle has thicker skin, to retain water and a needle-
like shape that reduces leaf area
d. they evolved fruit which are wet and keep the seed hydrated
Feedback
The correct answer is: the evolution of a pollen tube eliminated
the need for water in the transfer of sperm to the egg

Why does the plant invest so much energy in reproduction?
Select one:
a. if old plants did not generate new plants when the old plants
died the species would die
b. reproduction is an evolutionary artifact; plants no longer need
to invest as much energy but they still have not lost that trait
c. plants get too woody as they age and can't transport nutrients
efficiently; they need to reproduce to counteract the ageing
process
d. if there are not enough photosynthetic organisms in a specified
area photosynthesis is less efficient; new plants are needed to
keep up the rates of photosynthesis
Feedback
The correct answer is: if old plants did not generate new plants
when the old plants died the species would die
