Step-by-step solution
In gymnosperms, the sporophyte is the dominant phase and is heterosporous in nature, producing haploid microspores and megaspores. The male and female gametophytes are highly reduced and do not have an independent free-living existence; they are retained within the sporangia on the sporophyte. The leaves of gymnosperms (like the needle-like leaves of conifers) are well-adapted to withstand extremes of temperature, humidity, and wind. The ovules are naked, meaning they are not enclosed by any ovary wall, which is a
