Conifers are gymnosperms which produces naked seeds. Conifers reproduces sexually by producing male and female cones. Male cones are produced in cluster. Male cones contains many microsporangia.

Do you think animals pollinate flowers and disperse seeds on purpose or by accident?
Allushta [10]

Answer:

Animals most likely pollinate by accident.

Explanation:

Deer for example, they may graze in the grass. The pollen/seeds could catch onto their fur--and later fall off into a different area when they walk away. They could also eat a plant, and the seeds end up in their feces. Bees for another example don't necessarily <em>mean</em> to pollinate, they just happen to pick up pollen/seeds when they land on a flower for honey.

Hope this helps :)
