Answer:
Due to large size of genome.
Explanation:
The study of wheat genome is difficult task because of its large size. The genome of wheat comprise of 15 billion DNA bases. The wheat genome is three times bigger in size as compared to the genome of mammoth. Mammoth is an extincted specie of elephant which were the biggest land animal at that time. So due to large genome size of wheat, the scientists takes more time to complete its sequencing (order of nucleotide in the DNA).
The sporophyte generation of a moss dependent on the gametophyte generation is that it is used for support and most of its nutrients.A sporophyte is the diploid multicellular stage in the life cycle of a plant or alga and it<span> develops from the zygote produced.</span>
All cells have robosomes, DNA, cytoplasm and plasma membrane.
