Answer:
The gymnosperms are heterosporous; they produce haploid microspores and megaspores. The two kinds of spores are produced within sporangia that are borne on sporophylls which are arranged spirally along an axis to form lax or compact strobili or cones.

A lax is a loose aggregation of sporophylls.
- Gymnosperms are seed-bearing plants that do not produce flowers. They are phanerogamic sporophytic plants also known as naked seeded vascular plants.
- Gymnosperms produce megaspores as well as microspores and so they are heterosporous.
- The lax in the gymnosperms is spirally arranged along the axis produced within the sporangia. Besides that, they also produce compact strobili or cones.
