1. Naked Seeds, Gymnosperm means 'naked seed' and these were the earliest trees to evolve. They do not produce flowers and have seeds which are directly exposed to the air for wind pollination.

Synapse plasticity
The ability of a given synapse to strengthen or weaken over time is known as synapse plasticity. The strengthening or weakening is in direct relation to the amount and way the synapse is used. The more frequently and vigorously a synapse is involved in activities, the more it will strengthen, just as in the case of muscles. This mechanism is important in learning and also lays the foundation of memory in the brain.
