There are very fewer species of gymnosperms few examples of these plants are cypress Gnetum pine spruce redwood ginkgo cycads juniper fir and Welwitschia.

These are responsible for producing the secondary tissues. Interfascicular cambium and cork-cambium are examples of lateral meristems. Conifers produce seeds when the pollen from a male cones reaches the female cones.
