7. Gymnosperms


Gymnosperms (gymnos=naked, sperma=seed) are the naked-seeded plants.


They have very simple flowers without accessory whorls and stamens and carpels remain aggregated in cones. Ovules are present on the surface of the carpels and are directly pollinated by the pollen grains.

There is nothing like ovary, style and stigma, and naturally there is no fruit.

e.g. Cycas, Pinus, Gnetum.


Pine is the largest family. Gnetum and Cycas are mostly confined to North Eastern region, Eastern and Western Ghats, and Andaman & Nicobar Islands.

Do you know?


Polar bears evolved relatively recently (about 200,000 years to possibly as long as 500,000 years ago) from grizzly bears somewhere off eastern Russia or the Alaskan Panhandle. They depend on sea ice for their primary habitat for their food (mainly ringed seals and bearded seals). As the world’s oceans have never been frozen from the north to the south, polar bears simply didn’t have the possibility to reach the Antarctic, although it would have been a perfect home for them.

India has more than 7% of the world’s known flowering plants.
