what are the key structures in a flowering plant vs a fern that confer dispersal? Compare and contrast the structures
Homework Answers
Ferns usually use spores for dispersal.The spores develop in structures called sori (sin. sorus) which are generally present on the underside of the leaves (fronds). Wind appears to be the main agent of dispersal. Some fern spores may also be transferred by chance through animals. So the man dispersal processes are anemophily & zoophily.
In flowering plants, seeds instead of spores are subjected to dispersal. The fruits are eaten by animals, birds or humans & the seeds may be dispersed when they are released via excretion; also some light seeds may be dispersed through wind- large seeds (coconut) are dispersed via water. So the dispersal process depends on hydrophily, zoophily, anthrophily or anemophily.

Discuss the life histories of a pine (Coniferophyta) and a flowering plant (Anthophyta). Include in discussion: -the sequence of stages in the life histories of each and their reproductive structures -definitions of seeds and fruits including the structures of each -factors that have influenced the distribution and success of these seed-bearing plants (Hint: plant structure and form, mechanisms of water conservation and transport, pollination and seed dispersal mechanisms (including coevolution of the animal groups often involved in these mechanisms) should...
