"All organisms must insure that their offspring
have a reasonable chance to survive and begin a
new generation. Plants, however, face special

positions, they must also manage to find mates
without being able to move around. Therefore they
have evolved strategies for dealing with these
problems that are essentially passive. An
important part of such strategies is a
reproductive pattern enabling each individual to
produce large numbers of offspring."
