1.	Question : Heterospory is a development towards seed habit. Do you agree ?
Answer» Solution :Yes. Production of two types of spores by a plant is called heterospory . Eg: Selaginella. 2. Large spores are called mesaspores and small spores are called microspores. Megaspore `to` Female gametophytes `to` ARCHEGONIA `to`egg. Microspore `to` male gemetophyte `to` Antheridia `to` Antherozoids. 3. The two gemetophytes REMAIN protected inside the respective spores in the sporophytic phase. 4. Microspores are dispersed by wind and reach the Megaspore. The antherozoid fuses with the egg to formzygote. 5. THUS the gemetophytic generation is completed in the sporophyte plant itself. Only after ZYGOTE formation the female GAMETOPHYTE is shed from the sporophyte. 6. This is a basic requisite for seed habit.
