Characteristics of Gymnosperms(Conifers):
1) Gymnosperms do not have and outer-covering or shell around their seeds.
2)Gymnosperms do not produce flowers barring a few exceptions.
3)Gymnosperms are heterosporous which means that they produce different male and female spores. The microspores develop into pollen grains and the megaspores are in an ovule.
4)Gymnosperms produce cones.
5)Gymnosperms do not bear fruits.
6)Gymnosperms propagate via wind pollination.
Conifers are the largest division of gymnosperms. These conifers are found in the high latitudes of the northern hemisphere. There are several families of the Coniferphyta division as well. These are cone-bearing gymnosperms.
