Cone Function. Each coniferous tree produces both male and female cones. Male cones are much smaller and less showy than their female counterparts. During spring, pollen produced from the male cones is carried by the wind through the female cones fertilizing their egg cells and prompting them to produce seeds.dentification. Seeds are found in both coniferous and flowering plants. They range widely in size, from tiny, barely visible grains to large, bulbous nodules two inches or more in length. Seeds can be firm and fleshy, rough and woody, or hard and smooth.
Pollen cones are much smaller than their woody seed cone counterparts; they are usually produced in clusters at the tips of the lower branches of a tree. Mount a small amount of conifer pollen in a drop of water on a slide, and examine it with the aid of your compound microscope.. Understand the differences between male (pollen) and female (seed) pine cones. 4. Know the locations and functions of a pine micropyle, integument, pollen chamber, and nucellus. 5. Know the function of the bladders or wings on pine pollen grains.
