1. Which of the outcomes would occur if a moss had a mutation that inhibited the production of sporopollenin?
The spores would dry out more quickly.
The likelihood of outcrossing would decrease.
Spores would not be released from the sporangia.
The moss would not be able to produce pollen.
Sperm would not be able to reach eggs for fertilization.

Homework Answers
1. Sporopollenin is complex biopolymers which is very hard and stable. In spores sporopollenin prevent the drying and degeneration. So in absence of sporopollenin spores would dry more quickly.
2. The main difference between seed dispersing and spore dispersing plants are that sporophyte of seed plants are photosynthetic and independent along with the dispersal of seeds and pollen grains takes place in place of spores.

In ferns, both the gametophyte and sporophyte are physiologically capable of surviving on their own. Which of the following are reasonable hypotheses for why vascular tissues are present only in the sporophyte generation? Select all that apply. There is no advantage for the gametophyte to grow tall, because fern gametophytes typically produce only male or female gametes at any one time There is no advantage for the gametophyte to grow tall, because gametes must be produced near the ground where...
