The answer is Pollen and the Sugar cone.
male and female cones, and mature cones.

Conifer trees have two different kinds of cones. The pollen cones house the male reproductive cells. They produce pollen which is later transferred to the female cone to fertilize the seeds. The seed cone houses the female reproductive cells, which when pollinated become seeds.
More than likely what you are seeing are male and female pine cones which sometimes look different even if they are the same species.
The two kinds of receptor in the eye are rods and cones. Rods only see in black and white but are very light sensitive (that's why you see in black and white when it is almost dark) and cones which allow you to see in colour.
The retina has two kinds of photoreceptors: rods and cones. The rods help you see black-and-white movies, while the cones help you see in color. If you had neither one or lost both you wouldn't be able to see in black-and-white, color, or you would be blind.
You cannot because the volumes of the cones also depend on their heights.
Double cone is two cones joined at their apex.
