Final answer:
The bristlecone pine tree and the fish poison tree both carry out sexual reproduction.
Step-by-step explanation:
The fact that the cones produced by the bristlecone pine tree are either male or female, while the flowers of the fish poison tree contain both male and female parts, reveals that both trees carry out sexual reproduction. This means that they rely on the fusion of male and female reproductive cells (gametes) to produce offspring. Sexual reproduction allows for genetic diversity and the exchange of genetic material between individuals, which can be advantageous for these trees in adapting to changing environments.
In terms of seed dispersal, it is not specifically mentioned in the question, so we cannot make a definitive statement about the trees' seed dispersal capabilities. Additionally, the need for insects to carry out pollination is also not indicated in the question.
