Answer:
Spore/sporophyte
Explanation:
The sporophyte is the generation of plants that bear spores. Sporophytes are formed by a division in the zygote and are mostly diploid in nature. The specific structures present on the sporophyte are called sporangia. Spore mother cells present inside the sporangia undergo meiosis to produce haploid spores. For example, the diploid microspore mother cells present in the microsporangia in the anther of flowering plants divide by meiosis to produce haploid microspores.
Answer:
The correct answer is: Attachment.
Explanation:
- Pilus are thread like structures which are present on the surface of the bacterial cell.
- They are mainly responsible for attaching the bacterial cells to a substrate, for obtaining food or to an eukaryotic cell for the purpose of infection.
- Pilus also mediate the process of conjugation in some bacterial cells.
- Conjugation is a process by which genetic material or plasmids are transferred from one bacteria to another through a channel formed in between the two bacteria by the help of the pilus.
- Pilus also helps the bacteria by preventing them from getting recognised by the immune cells in the host.
- A defective pilus will affect all the above processes, resulting in death of the bacteria.
