Plant Life Cycle Gymnosperm Manufacturer,Supplier and Exporter in India
Product Code : EL-BL-12050
Jlab Export is a leading Plant Life Cycle Gymnosperm Manufacturer,and suppliers in India
Plant Life Cycle Gymnosperm (code EL-BL-12050) is a teaching chart on how gymnosperms reproduce, the seed plants whose ovules are borne exposed rather than inside an ovary. It pairs naturally with lessons on conifers and on the evolution of the seed. Printed in Ambala, India, by JLab, it belongs to the same series as the angiosperm, bryophyte and pteridophyte life-cycle charts.

Cones, Naked Seeds and a Slow Fertilisation
The tree or shrub is the diploid sporophyte. Male cones release pollen, carried mostly by wind, and female cones bear the ovules on their scales. Inside each ovule a haploid female gametophyte forms archegonia with egg cells, and the same tissue later stores food for the embryo. A pollen tube delivers the male gametes; in pines this happens about a year after pollination. With no ovary there is no fruit, so the seed is shed bare.
