उत्तर
Pollen tube - spores
Explanation:
A pollen tube is not a spore. It is a tubular structure that develops from a pollen grain (male gametophyte) after it lands on the stigma. The pollen tube grows through the style to deliver sperm cells to the ovule for fertilization. Spores, in contrast, are haploid reproductive cells that develop into gametophytes and are not involved in forming pollen tubes.
